Hi I want to write Arabic in Java in Android and this is the code
public class hospital extends Activity {
ListView listView,l1;
ArrayAdapter<String> adapter,adapter1,adapter2;
String[] location,loc1,loc2;
Button home,map;
TextView name,address,phone;
WebView maps;
String hospital_name,hospital_address,hospital_phone,url;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.hospital_location);
home = (Button)findViewById(R.id.home);
home.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
startActivity(new Intent(hospital.this, MainActivity.class ));
finish();
}
});
listView = (ListView) findViewById(R.id.hospital_list_location);
location = new String[] { "Al rabia","Tabarbor","Tla' al Ali","Daheat elrawda" };
This code will write like in the photo
And when I want to write Arabic in location like this. location=new String[]{"مستشفى هبه"}
It's want work and appear a strange words
Android can't handle the simple arabic letters (unicode 0x06xx). You need to use arabic presentation characters (0xFExx), and join the letters together yourself.
You also need to find a nice arabic font on the web- I use "AGA Rashheeq Bold"- and put it into your assets, then load it like this
Typeface tfArabic = Typeface.createFromAsset (getAssets (), "AGA-Rasheeq-Bold.ttf");
Then use something like this to use the font:
NextButton.setTypeface (tfArabic);

Hello I want to have an Add function that allows me to input items to my GridView
For Background: I have a standard GridView and an XML activity (which contains 2 TextView) that I want to convert to my GridView. I also have a custom ArrayAdapter class and custom Word object (takes 2 Strings variables) that helps me do this.
My problem: I want to have an Add button that takes me to another XML-Layout/class and IDEALLY it input a single item and so when the user goes back to MainActivity the GridView would be updated along with the previous information that I currently hard-coded atm. This previous sentence doesn't work currently
Custom ArrayAdapter and 'WordFolder' is my custom String object that has 2 getters
//constructor - it takes the context and the list of words
WordAdapter(Context context, ArrayList<WordFolder> word){
super(context, 0, word);
}
#Override
public View getView(int position, View convertView, ViewGroup parent){
View listItemView = convertView;
if(listItemView == null){
listItemView = LayoutInflater.from(getContext()).inflate(R.layout.folder_view, parent, false);
}
//Getting the current word
WordFolder currentWord = getItem(position);
//making the 2 text view to match our word_folder.xml
TextView title = (TextView) listItemView.findViewById(R.id.title);
title.setText(currentWord.getTitle());
TextView desc = (TextView) listItemView.findViewById(R.id.desc);
desc.setText(currentWord.getTitleDesc());
return listItemView;
}
}
Here is my NewFolder code. Which sets contentview to a different XML. it's pretty empty since I'm lost on what to do
public class NewFolder extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_folder_view);
Button add = (Button) findViewById(R.id.add);
//If the user clicks the add button - it will save the contents to the Word Class
add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//make TextView variables and cast the contents to a string and save it to a String variable
TextView name = (TextView) findViewById(R.id.new_folder);
String title = (String) name.getText();
TextView descText = (TextView) findViewById(R.id.desc);
String desc = (String) descText.getText();
//Save it to the Word class
ArrayList<WordFolder> word = new ArrayList<>();
word.add(new WordFolder(title, desc));
//goes back to the MainActivity
Intent intent = new Intent(NewFolder.this, MainActivity.class);
startActivity(intent);
}
});
}
In my WordFolder class I made some TextView variables and save the strings to my ArrayList<> object but so far it's been useless since it doesn't interact with the previous ArrayList<> in ActivityMain which makes sense because its an entirely new object. I thought about making the ArrayList a global variable which atm it doesn't make sense to me and I'm currently lost.
Sample code would be appreciative but looking for a sense of direction on what to do next. I can provide other code if necessary. Thank you
To pass data between Activities to need to do a few things:
First, when the user presses your "Add" button, you want to start the second activity in a way that allows it to return a result. this means, that instead of using startActivity you need to use startActivityForResult.
This method takes an intent and an int.
Use the same intent you used in startActivity.
The int should be a code that helps you identify where a result came from, when a result comes. For this, define some constant in your ActivityMain class:
private static final int ADD_RESULT_CODE = 123;
Now, your button's click listener should looks something like this:
addButton.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent intent=new Intent(MainActivity.this, NewFolder.class);
startActivityForResult(intent, ADD_RESULT_CODE);
}
});
Now for returning the result.
First, you shouldn't go back to your main activity by starting another intent.
Instead, you should use finish() (which is a method defined in AppCompatActivity, you can use to finish your activity), this will return the user to the last place he was before this activity - ActivityMain.
And to return some data, too, you can use this code:
Intent intent=new Intent();
intent.putExtra("title",title);
intent.putExtra("desc",desc);
setResult(Activity.RESULT_OK, intent);
where title and desc are the variables you want to pass.
in your case it should look something like this:
public class NewFolder extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.new_folder_view);
Button add = (Button) findViewById(R.id.add);
//If the user clicks the add button - it will save the contents to the Word Class
add.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View view) {
//make TextView variables and cast the contents to a string and save it to a String variable
TextView name = (TextView) findViewById(R.id.new_folder);
String title = (String) name.getText();
TextView descText = (TextView) findViewById(R.id.desc);
String desc = (String) descText.getText();
//Save it to the Word class
ArrayList<WordFolder> word = new ArrayList<>();
word.add(new WordFolder(title, desc));
Intent intent=new Intent();
intent.putExtra("title",title);
intent.putExtra("desc",desc);
setResult(Activity.RESULT_OK, intent);
//goes back to the MainActivity
finish();
}
});
}
You should probably also take care of the case where the user changed his mind and wants to cancel adding an item. in this case you should:
setResult(Activity.RESULT_CANCELLED);
finish();
In your ActivityMain you will have the result code, and if its Activity.RESULT_OK you'll know you should add a new item, but if its Activity.RESULT_CANCELLED you'll know that the user changed their mind
Now all that's left is receiving the data in ActivityMain, and doing whatever you want to do with it (like adding it to the grid view).
To do this you need to override a method called onActivityResult inside ActivityMain:
// Call Back method to get the Message form other Activity
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data)
{
super.onActivityResult(requestCode, resultCode, data);
// check the result code to know where the result came from
//and check that the result code is OK
if(resultCode == Activity.RESULT_OK && requestCode == ADD_RESULT_CODE )
{
String title = data.getStringExtra("title");
String desc = data.getStringExtra("desc");
//... now, do whatever you want with these variables in ActivityMain.
}
}
im programming an app to sort numbers and display the sorting process
after the input is sorted , a new button will be showen to display the selection sort steps in a new activity
[SelectionSort activity 1
I want the output of the function SelectionSortMethod in SelectionSortclass to be displayed in a new activity activity_Ssteps
SelectionSort.java :
public class SelectionSort extends AppCompatActivity {
EditText input;
EditText output;
Button Ssteps ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_selection_sort);
input=findViewById(R.id.input);
output=findViewById(R.id.output);
Ssteps = findViewById(R.id.steps);
Ssteps.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
Intent s = new Intent(SelectionSort.this, com.example.sorted.Ssteps.class);
startActivityForResult(s, 1);
}
});}
public void sortButtonPressed(View view){
String[] numberList = input.getText().toString().split(",");
Integer[] numbers = new Integer[numberList.length];
for (int i = 0; i < numberList.length; i++) {
numbers[i] = Integer.parseInt(numberList[i]);
}
SelectionSortmethod(numbers);
output.setText(Arrays.toString(numbers));
// if button "sort " is pressed , the button "view steps "will be displayed
Ssteps.setVisibility(View.VISIBLE);
}
}
public static void SelectionSortmethod (Integer[] arr)
{
// some code for sorting and showing the steps
}
Ssteps.java :
public class Ssteps extends AppCompatActivity {
TextView steps_text ;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_ssteps);
setTitle("selection sort steps ");
steps_text =findViewById(R.id.Stepstextview);
}
}
You can just use intent.extras like so:
Intent s = new Intent(SelectionSort.this, com.example.sorted.Ssteps.class);
s.putExtra("AnyID",YOURDATA);
startActivity(s);
And then in your Ssteps.class you can get the data using
the id like this:
String ss = getIntent.getExtra("AnyID"); //the id is the same as the other one above
steps_text.settext(ss);
Working with Intents like Youssof described is the way to go for small applications like yours. However as you progress in Android programming, you should definitely have a look at splitting your application in Fragments rather than Activities. They can use a Viewmodel, which makes sharing lots of data between screens much easier. Also Fragments can be use in androidx Navigation component, whos changing Fragments can be beautifully arranged in a UI. Very convenient for product reviews.
I'm creating a lyric app and I need some help in coding the next processes I need.
I created a ListView and added some Strings on it.
public class MainActivity extends AppCompatActivity {
String titles[] = new String [] {"Amazing Grace", "How Great Thou Art",
"King of All Kings", "What A Beautiful Name"};
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ListView listView =(ListView) findViewById(R.id.titlelist);
ArrayAdapter<String> adapter=new ArrayAdapter<String>
(this,android.R.layout.simple_list_item_1,titles);
listView.setAdapter(adapter);
}
}
Now the next step is to create an OnItemClickListener and let's say
if "Amazing Grace" was selected from the list,
it will look for a file the same name as it is defined in the String.
For example : "Amazing Grace.xml" //even with the space included
so the logic will be like : open filelocation/"title that was selected".xml
I can't use "case" since I will be creating lots of song titles and add more as I update the app.
Thanks for reading, I'd really appreciate any help with this ;)
You should map Your lyrics, so when You click on item with pos = 5 You will know what item's ps correlates with what file(or xml).
Here is the sample how to map ids with filenames:
HashMap<String,Strin> lyricsMap = new HashMap<>();
lyricsMap(0, R.raw.song_lyric0);
lyricsMap(1, R.raw.song_lyric1);
lyricsMap(2, R.raw.song_lyric2);
lyricsMap(3, R.raw.song_lyric3);
lyricsMap(4, R.raw.song_lyric4);
lyricsMap(5, R.raw.song_lyric5);
lyricsMap(6, R.raw.song_lyric6);
//..
Here is the sample how to use OnItemClickListener:
AdapterView.OnItemClickListener onItemClickListener = new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adapterView, View view, int pos, long id) {
int rawResId = lyricsMap.get(pos);
//here comes the method for returning lyrics for file by it's resource id
//...
}
};
adapter.setOnItemClickListener(onItemClickListener);
P.S I assume You are not working on database items, otherwise You should use id instead of pos value.
To open file:
int selected = 0; // set selected to index of what is selected
File file = new File(Environment.getExternalStorageDirectory(), //folder location where you store the files
titles[selected]+".xml"); //in case of xml files. If other types, you'll need to add case for diff types
Uri path = Uri.fromFile(file);
Intent fileOpenintent = new Intent(Intent.ACTION_VIEW);
fileOpenintent .setDataAndType(path, "application/xml"); //for xml MIME types are text/xml and application/xml
try {
startActivity(fileOpenintent);
}
catch (ActivityNotFoundException e) {
}
Your biggest issue as you explained it was how to handle multiple file names. That's this part of code: titles[selected]+".xml"
public class MainActivity extends AppCompatActivity {
TextView hi;
Typeface ty;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
hi = (TextView) findViewById(R.id.hi);
ty = Typeface.createFromAsset( getAssets() , "fonts/Spirax-Regular.ttf");
hi.setTypeface(ty);
}
}
this code worked very well for me.
My question is if my application support two languages which are (Arabic and English), is there any way to add two types of fonts to the same text? one for the Arabic Text and the other for the English one?
Try this
if(Locale.getDefault().getISO3Language().equals("ar")){
//LANGUAGE IS ARABIC
text.setTypeface(arabicTypeface);
}
else{
//LANGUAGE IS ENGLISH
text.setTypeface(englishTypeface);
}
This is not the proper way but this will solve your problem
textView.setText(Html.fromHtml(text));
This type of example is use to simply change the text font.
Solution :
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
hi = (TextView) findViewById(R.id.tvTime);
setContentView(R.layout.activity_main);
if(getResources().getConfiguration().locale.getLanguage().equals("ar"))
hi.setTypeface(Typeface.createFromAsset( getAssets() , "YOUR ARABIC .TTF FILE HERE"));
else if(getResources().getConfiguration().locale.getLanguage().equals("en"))
hi.setTypeface(Typeface.createFromAsset( getAssets() , "YOUR ENGLISH .TTF FILE HERE"));
}
I am creating an android dictionary app with sounds... I have listview, when an item is selected, a new activity open, inside the new activity contains 4 textviews and an image button, the textviews function perfectly but the image button was not. The audio files are placed in raw folder. How can I put the specific sounds of an item that was clicked?
Here's the code:
MainActivityJava
public class MainActivity extends AppCompatActivity {
ListView lv;
SearchView sv;
String[] tagalog= new String[] {"alaala (png.)","araw (png.)","baliw (png.)","basura (png.)",
"kaibigan (png.)","kakatuwa (pu.)", "kasunduan (png.)","dambuhala (png.)",
"dulo (png.)","gawin (pd.)","guni-guni (png.)","hagdan (png.)","hintay (pd.)",
"idlip (png.)","maganda (pu.)","masarap (pu.)", "matalino (pu.)"};
int[] sounds= new int[]{R.raw.alaala,
R.raw.araw,
R.raw.baliw,
R.raw.basura,
R.raw.kaibigan,
R.raw.kakatuwa,
R.raw.kasunduan,
};
ArrayAdapter<String> adapter;
#TargetApi(Build.VERSION_CODES.HONEYCOMB)
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
lv = (ListView) findViewById(R.id.listView1);
sv = (SearchView) findViewById(R.id.searchView1);
adapter = new ArrayAdapter<String>(this, android.R.layout.simple_list_item_1,tagalog);
lv.setAdapter(adapter);
lv.setOnItemClickListener(new OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
String tagword =tagalog[position];
String[] definition = getResources().getStringArray(R.array.definition);
final String definitionlabel = definition[position];
String[] cuyuno = getResources().getStringArray(R.array.cuyuno);
final String cuyunodefinition = cuyuno[position];
String[] english = getResources().getStringArray(R.array.english);
final String englishdefinition = english[position];
Intent intent = new Intent(getApplicationContext(), DefinitionActivity.class);
intent.putExtra("tagword", tagword);
intent.putExtra("definitionlabel", definitionlabel);
intent.putExtra("cuyunodefinition",cuyunodefinition);
intent.putExtra("englishdefinition", englishdefinition);
startActivity(intent);
}
});
sv.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
#Override
public boolean onQueryTextSubmit(String text) {
return false;
}
#Override
public boolean onQueryTextChange(String text) {
adapter.getFilter().filter(text);
return false;
}
});
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
return super.onCreateOptionsMenu(menu);
}
}
DefinitionActivity.java
public class DefinitionActivity extends AppCompatActivity {
MediaPlayer mp;
String tagalogword;
String worddefinition;
String cuyunoword;
String englishword;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_definition);
TextView wordtv = (TextView) findViewById(R.id.wordtv);
TextView definitiontv = (TextView) findViewById(R.id.definitiontv);
TextView cuyunotv = (TextView) findViewById(R.id.cuyunotv);
TextView englishtv = (TextView) findViewById(R.id.englishtv);
ImageButton playbtn = (ImageButton) findViewById(R.id.playbtn);
final Bundle extras = getIntent().getExtras();
if (extras != null) {
tagalogword = extras.getString("tagword");
wordtv.setText(tagalogword);
worddefinition = extras.getString("definitionlabel");
definitiontv.setText(worddefinition);
cuyunoword = extras.getString("cuyunodefinition");
cuyunotv.setText(cuyunoword);
englishword = extras.getString("englishdefinition");
englishtv.setText(englishword);
}
playbtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
}
});
}
you can pass the raw id in the intent extra and play it on meadiaPlayer
What you want to accomplish is pretty simple.
you can ofcourse pass the id.
But I created this method for your case you can paste it in your activity or class and make a call to it. In my case, I put this method in a class that holds all the common functions, methods, strings, etc. The choice is yours :
public static void playDisSound(Context c, int soundID){
//Play short tune
MediaPlayer mediaPlayer = MediaPlayer.create(c, soundID);
mediaPlayer.setOnCompletionListener( new OnCompletionListener(){
#Override
public void onCompletion( MediaPlayer mp){
mp.release();
}
});
mediaPlayer.start();
}
And this is how to use it in your case :
Example I want to play an audio track from :
int[] sounds= new int[]{R.raw.alaala,
R.raw.araw,
R.raw.baliw,
R.raw.basura,
R.raw.kaibigan,
R.raw.kakatuwa,
R.raw.kasunduan,
};
So I just do :
//TODO ~ pls. remember to define context inside "onCreate" as
//call this before "onCreate"
Context context;
//And do this inside "onCreate" :
context = getApplicationContext();
OR
context = MainActivity.this;
//Then here comes the solution, just make a call to the playDisSound method with the id , in this case the "sounds[postion_referencer_i]"
playDisSound(context, sounds[postion_referencer_i]);
//And now on the question of what your "position_referencer_i" would be .... it also depends on how you intend to pass the id.
Are your going to make a match between the position picked and the position of the sound. It depends on you. But I would have created a set of integers to signify which try I want to play and do a matching simple calculation between the position picked for the item clicked to arrive at the position_referencer_id.
//But simply : note that in your array if I want to play for example "R.raw.baliw" I would just call :
playDisSound(context, R.raw.baliw);
I hope this works perfectly for you. So if I elaborated too much. Do let me know if you may need to stream the sound so I would just paste/send you a very cool method I have been using here in an app am working.
//FINALLY PLS. Remember this : this method would play the sound alright but it wont hesitate to play the sound all over again if you repeat the process. So do remember to check if the sound did play and finished before allowing the user to repeat, if not it could lead to repeated or kind of two speakers playing from the same song but at different time. (And the user may start to think that there is problem with the app. Pls. be very logical and sensitive in using this method)
In solving that, you can disable the button or the UI element that initiates the sound playing until the sound has finished playing, by way of monitoring duration of the track (which I am sure you should know and inculcate into your logic or by simply listening if sound is already playing)
All the best. Era. :)
