I'm trying to take a text from the EditText widget and send it to a second activity, here is what I wrote until now:
package example.antonio.anexample;
import android.content.Intent;
import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.text.Editable;
import android.view.View;
import android.widget.LinearLayout;
import android.widget.EditText;
import android.widget.Button;
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
EditText etxt = new EditText(this);
etxt.setHint("Write something");
Button btn = new Button(this);
btn.setText("Send");
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Editable input = etxt.getText();
Intent i = new Intent(MainActivity.this, SecondActivity.class);
i.putExtra("message", input.toString());
startActivity(i);
}
});
LinearLayout layout = new LinearLayout(this);
layout.setOrientation(LinearLayout.VERTICAL);
layout.addView(etxt);
layout.addView(btn);
setContentView(layout);
}
}
But as you can image it doesn't compile, how can I access the etxt variable from the inner class?
Make etxt final so you can access it on inner class
final EditText etxt = new EditText(this);
etxt.setHint("Write something");
Button btn = new Button(this);
btn.setText("Send");
btn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String input = etxt.getText();
Intent i = new Intent(MainActivity.this, SecondActivity.class);
i.putExtra("message", input.toString());
startActivity(i);
}
});

I am trying to get the input from the EditText fields and store it into an SQLite database. But the Fields are null even after I enter text into it.
I did a similar thing earlier and it ended up just fine but I am confused what is causing the problem here.

import android.content.Intent;
import android.net.Uri;
import android.provider.MediaStore;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.TextView;
import android.widget.Toast;
public class CreateEvent extends AppCompatActivity {
EditText edit,edit2,edit3,edit4;
TextView t1;
ImageView img;
Button bpost;
public static final int PICK_IMAGE=1;
Uri imageuri;
Event in;
DatabaseHelper dc = new DatabaseHelper(this);
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_create_event);

public void onClick(View vim){
operationGallery();
}
});
bpost.setOnClickListener(new View.OnClickListener(){
public void onClick(View vPost){
in.sEventName(edit.getText().toString()); //Problem here
in.sEventDesc(edit2.getText().toString());
in.sEventVenue(edit3.getText().toString());

}
});
} public void operationGallery(){
Intent im = new Intent(Intent.ACTION_PICK, MediaStore.Images.Media.INTERNAL_CONTENT_URI);
startActivityForResult(im , PICK_IMAGE);
}
public void onActivityResult(int requestcode, int resultcode, Intent data){
super.onActivityResult(requestcode, resultcode, data);
if((resultcode == RESULT_OK)&&(requestcode == PICK_IMAGE)){

img.setImageURI(imageuri);
}
}
}
The following is the error which I am getting after executing the code
You have just forgot to initiate Event object "in"
Your Event object in is uninitialized.
In my code, I have a class for a recipe and then another class for each step. The recipe class holds an arraylist of the steps in that recipe.
I have 3 processes being called one after the other:
MainActivity calls AddEditRecipe using startActivityResult
within AddEditRecipe I have another startActivityResult which calls AddStep
within AddStep I am adding a new instance of step to the list in the recipe.
It successfully adds the object to the list before finish() is called, but when I check the size of the list when I have gone to the 2nd activity it has reverted back to 0, even though I've managed to create buttons with the data I collected from the AddStep functions.
Basically I don't know what to do make it so it everything correctly persists.
Also a heads up, I am still fairly new too java so there's probably lots of other things wrong, any random advice is greatly appreciated.

I'm trying to make an APK that saves passwords with the site using two different ArrayLists. This way, I can get the right indexnumber of the site and get the password based on this indexnumber. In the beginning of MainActivity, I add two random Strings to the ArrayLists, so that I don't have to work with empty ArrayLists, but this is utterly useless I think.
The problem is I can only view the last site-password I have put in. Previous combinations are "lost."

When you exit an Activity, all the data on it is lost. You have to persist your ArrayList in SQLite or use SharedPreferences instead.
SharedPreferences: https://developer.android.com/reference/android/content/SharedPreferences.html
SQLite: https://developer.android.com/training/basics/data-storage/databases.html
I'm having a rather strange issue that I just can't solve.
I'm teaching myself Android Eclipse and I've created a very simple looking app with three buttons, 1)Facebook 2)LinkedIn and 3)Favourite Band. However, when I open the app on my phone, I can only press the buttons in order 1) --> 2) --> 3). For example, I can't open 2) unless i've already opened 1) and I can't open 3) unless I've already opened 2) etc. How can I change it so that I can open 3) first for example?
I've posted my java script below, any ideas would be great!
package tabletop.app4asli;
import android.app.Activity;
import android.content.Intent;
import android.media.MediaPlayer;
import android.net.Uri;
import android.os.Bundle;
import android.util.Log;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.Button;
public class MainActivity extends Activity {
MediaPlayer thesong;
Button main;
Button main2;
Button main3;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
main = (Button) findViewById(R.id.btn_go);
main.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String url = "https://www.facebook.com/asli.akidil?fref=ts";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
main2 = (Button) findViewById(R.id.button2);
main2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String url = "https://www.linkedin.com/pub/asli-akidil/8a/719/55a.";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
main3 = (Button) findViewById(R.id.button3);
main3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String url = "http://www.biffyclyro.com";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
It's because the code for the layout of button 2 is included in the onClick event of your button 1, and the layout of button 3 is included in the onClicked event of your button 2.
The code of onCreated() function should be looked like follows:
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
main = (Button) findViewById(R.id.btn_go);
main.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String url = "https://www.facebook.com/asli.akidil?fref=ts";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
});
main2 = (Button) findViewById(R.id.button2);
main2.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String url = "https://www.linkedin.com/pub/asliakidil/8a/719/55a.";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
});
main3 = (Button) findViewById(R.id.button3);
main3.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
String url = "http://www.biffyclyro.com";
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
});
}
You are setting ClickListener for button 3 in the ClickListener of button 2 and ClickListener for button 2 in the ClickListener of button 1. So, button 2 and 3 won't initialize until button 1 and 2 are clicked respectively. You can set OnClickListener to all Buttons in a for loop like this:
ArrayList<Button> buttonList = new ArrayList<Button>();
buttonList.add((Button) findViewById(R.id.button1));
buttonList.add((Button) findViewById(R.id.button2));
buttonList.add((Button) findViewById(R.id.button3));
ArrayList<String> urlList = new ArrayList<String>();
urlList.add("https://www.facebook.com/asli.akidil?fref=ts");
urlList.add("https://www.linkedin.com/pub/asli-akidil/8a/719/55a.");
urlList.add("http://www.biffyclyro.com");
for (int i = 0; i < buttonList.size(); i++) {
final int index = i;
final Button button = buttonList.get(index);
final String url = urlList.get(index);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View arg0) {
Intent i = new Intent(Intent.ACTION_VIEW);
i.setData(Uri.parse(url));
startActivity(i);
}
});
}
I finally learned about adding a button to a page and actually making it navigate to another activity "XML Page". Anyway, I have been trying to add 2 buttons in the same page which navigate each to a different XML's Pages. All I did was copy the first button which worked and then change the button name and all other things the first button works but the second isn't. It shows a click but nothing happens after.
Back1 Button works. TMode Button does the trouble.
Eclipse is not showing errors.
Here is my code -
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class GameMode extends Activity {
/** Called when the activity is first created.*/
Button btn;
Button btn1;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game_mode);
btn=(Button)findViewById(R.id.Back1);
btn.setOnClickListener(btn2Listener);
}
private OnClickListener btn2Listener=new OnClickListener() {
public void onClick(View v) {
Intent intent2=new Intent(GameMode.this,MainActivity.class);
startActivity(intent2);
}
};
public void onCreate1(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game_mode);
btn=(Button)findViewById(R.id.TMode);
btn.setOnClickListener(btn3Listener);
}
private OnClickListener btn3Listener=new OnClickListener() {
public void onClick(View v) {
Intent intent3=new Intent(GameMode.this,CharacterSelect.class);
startActivity(intent3);
}
};
}
Try something like this:
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class GameMode extends Activity {
Button btn1;
Button btn2;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game_mode);
btn1=(Button)findViewById(R.id.Back1);
btn1.setOnClickListener(btn1Listener);
btn2=(Button)findViewById(R.id.TMode);
btn2.setOnClickListener(btn2Listener);
}
private OnClickListener btn1Listener=new OnClickListener() {
public void onClick(View v) {
Intent intent1=new Intent(GameMode.this,MainActivity.class);
startActivity(intent2);
}
};
private OnClickListener btn2Listener=new OnClickListener() {
public void onClick(View v) {
Intent intent1=new Intent(GameMode.this,CharacterSelect.class);
startActivity(intent2);
}
};
}
You should in your XML file define two buttons
<Button
android:id="#+id/button1"
... />
<Button
android:id="#+id/button2"
... />
And then in your Activity in onCreate() method you do
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
...
})
Button button2 = (Button) findViewById(R.id.button2);
button2.setOnClickListener(new OnClickListener() {
...
});
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class GameMode extends Activity {
Button btn1;
Button btn2;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_game_mode);
btn1=(Button)findViewById(R.id.Back1);
btn1.setOnClickListener(btn1Listener);
btn2=(Button)findViewById(R.id.TMode);
btn2.setOnClickListener(btn2Listener);
}
private OnClickListener btn1Listener=new OnClickListener() {
public void onClick(View v) {
Intent intent1=new Intent(GameMode.this,MainActivity.class);
startActivity(intent1);
}
};
private OnClickListener btn2Listener=new OnClickListener() {
public void onClick(View v) {
Intent intent2=new Intent(GameMode.this,CharacterSelect.class);
startActivity(intent2);
}
};
}
