I have made an android app to display image from firebase into recycler view and when user click a image it has to go to its full screen page and have tried a several times but it just shows the blank activity
You can use PhotoView library (com.github.chrisbanes.photoview) to show full screen picture as below:
Piccaso is used here to show images, but you can use other image libraries such as Fresco, Glide .

I'm having a bit of an issue, I'm working on a android app that requires a spinner to update a string to your spinner selection, I have it all working and everything, the problem is that I need the spinner on another activity than the starting activity but when I start the app with a different activity than the one with the spinner and activate the array adapter and listener at the same time I switch views to the one with the spinner, the spinner is empty with no choices. I can't for the life of me figure this out. PS, sorry about the weird variable names I get bored and instead of making a proper name I think of something on the spot and come back and change it later. PPS The name of the content view with the spinner is orderpage and the one I want to have start with the app is activity_main PPPS I cut out some methods I deemed irrelevant so there are some variables not used. I attached my code below:

On the 6th line of the onCreate method in the first code sample, if(deeznuts = true) should be if(deeznuts == true).
I am making this question today because I can not find certain information on google and/or Stack Overflow. My Problem is, I am creating a Android Application and I want certain information from a Website. So I use Jsoup as my parse Library. I follow all the instruction and set The data in the Text to Show up with The HTML text. For Some reason it is either a network connection or my code is wrong in communicating with the website? I do not know what is up with the app. I am Using Android Studio, so when running either the emulator or on a device it will just not pull html from the website.
Here is My code for 2 Classes. This has to be in Java.

import android.widget.TextView;
import android.widget.Toast;
import java.net.URL;
import java.net.URLConnection;
public class MainActivity extends Activity {
private Button answer_Button;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
RelativeLayout bible = new RelativeLayout(this);
}
#Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}
#Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.
return super.onOptionsItemSelected(item);
}
public void gotoInbeddedBible(MenuItem item) {
Intent bibleclass = new Intent(this, bible.class);
final int result = 1;
bibleclass.putExtra("callingActivity", "MainActivity");
startActivity(bibleclass);
startActivityForResult(bibleclass, result);
}
#Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
super.onActivityResult(requestCode, resultCode, data);
}
public void exit(MenuItem item) {
Button exitProcess = (Button) findViewById(R.id.submit);
android.os.Process.killProcess(android.os.Process.myPid());
System.exit(1);
}
public void sotd(MenuItem item) {
Intent clickedSotd = new Intent(this, Sotd.class);
int result = 1;
startActivity(clickedSotd);
}
}
This is the class I want to use Jsoup in.

Pretty Much I just need someone to tell me what I am doing wrong./Review
I am trying to add and delete items in my todo list. It adds the items fine but I have set up a onLongClickListener for deleting the items and it does nothing. I am a beginner so I may have missed something. Please help me out. Any help is appreciated.

public class MainActivity extends Activity implements OnClickListener{
private ArrayList<String> items;
private ArrayAdapter <String> adapter;
private EditText ptadd;
private Button badd;
private ListView lvTodo;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initialize();
items = new ArrayList <String>();
adapter = new ArrayAdapter<String>(this,adroid.R.layout.simple_list_item_1, items);
lvTodo.setAdapter(adapter);
setListViewListener();
}
private void setListViewListener(){
lvTodo.setOnItemLongClickListener(new OnItemLongClickListener (){
#Override
public boolean onItemLongClick(AdapterView<?> vadapter, View item,
int position, long id) {
// TODO Auto-generated method stub
items.remove(position);
adapter.notifyDataSetChanged();
return true;
}
});;
}
private void initialize() {
// TODO Auto-generated method stub
ptadd = (EditText) findViewById(R.id.etadd);
lvTodo = (ListView) findViewById(R.id.lvTodo);
badd = (Button) findViewById(R.id.badd);
badd.setOnClickListener(this);
}
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String lv = ptadd.getText().toString();
adapter.add(lv);
ptadd.setText("");
}
}
my XML file:
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="wrap_content"
android:layout_weight="30"
android:layout_alignParentBottom="true"

android:text="Add"

</RelativeLayout>
In the code you posted, you're never calling setListViewListener. Call the method in initialize
private void initialize() {
// TODO Auto-generated method stub
ptadd = (EditText) findViewById(R.id.etadd);
lvTodo = (ListView) findViewById(R.id.lvTodo);
badd = (Button) findViewById(R.id.badd);
badd.setOnClickListener(this);
//Missing this
setListViewListener();
}
Here's the XML layout:

android:text="Select any of the models below and press Info for the model's specifications"
android:id="#+id/textViewML"
android:layout_below="#+id/imageView2"
android:layout_alignLeft="#+id/model_list" />
And using the setContentView method results in an 'Application stopped working'.
setContentView(R.layout.search_hisp);
Any idea on how to fix this? I'm quite new to Android Development and still trying to find how to switch layouts the correct way.
Well, even I change the onCreate()' setContentView to R.layout.search_hisp and gave me the error on startup. So my guess is it's probably from the XML file or something.
Thanks in advance!
Edit, there's the error:

Because in onCreate() you have used
EditText textViewML = (EditText) findViewById(R.id.textViewML);
instead of
TextView txt = (TextView) findViewById(R.id.textViewML);
so you got problem. So you need to use after your setContentView() method.
TextView txt = (TextView) findViewById(R.id.textViewML);
Put in the onCreate :
TextView textViewML = (TextView) findViewById(R.id.textViewML);
The error was from
((EditText) g(R.id.rh)).setText("Test##".toCharArray(), 0, "Test##".length());
Thanks a lot guys for pointing this out!
you are casting Textview to EditText dont do that
EditText textViewML = (EditText) findViewById(R.id.textViewML);
change it as
TextView textViewML = (TextView) findViewById(R.id.textViewML);
Exception is not your layout file it is in your java file you are casting TextView into EditText.
You can not Cast Super class in to sub class.
you can cast Sub class into Super Class.
You can Cast EditText into TextView but not TextView in to EditText.
Change this line
TextView txt = (TextView) findViewById(R.id.textViewML);
Thanx
