Apps Unexplained "error"

[Nickvkaam]

Hey Guys/gals,

I was doing some tutorials, when I finished one i ran in to a problem.

The code down here shows an error in Eclipse:

btnDialog.setOnClickListener(new OnClickListener() {

I got 3 of these listeners.

The auto correct tools only suggests to change setOnClickListener to any other listener. I've searched the web a bit but didn't find an awnser.

Bellow if the whole code:

package app.weaselmummy.androidtest;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.AlertDialog.Builder;
import android.content.DialogInterface;
import android.content.DialogInterface.OnClickListener;
import android.content.Intent;
import android.media.MediaPlayer;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;

public class testApp extends Activity {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

final Builder dialog = new AlertDialog.Builder(this);
dialog.setTitle(R.string.dialog_title);
dialog.setMessage(R.string.dialog_text);
dialog.setPositiveButton(R.string.dialog_ok, null);
dialog.setNegativeButton(R.string.dialog_cancel, null);

Button btnDialog = (Button) findViewById(R.id.Button01);
btnDialog.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
dialog.show();
}
});

Button btnSound = (Button) findViewById(R.id.Button02);
btnSound.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
MediaPlayer player = new MediaPlayer();
try {
player.setDataSource(getString(R.string.sound_file));
player.prepare();
player.start();
} catch (Exception e) {
e.printStackTrace();
}
}
});

Button btnRelative = (Button) findViewById(R.id.Button03);
btnRelative.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
Intent i = new Intent(testApp.this, Relative.class);
startActivity(i);
finish();
}
});
}
}


Would appreciate any help!

In your imports list you have:

import android.content.DialogInterface.OnClickListener;

Remove this and replace it with:

import android.view.View.OnClickListener;

 

[santoshmadalli]

you can implement onClickListener and then implement onClick(Veiw v) method.

Below is the code for your reference,

import android.app.Activity;
import android.os.Bundle;
import android.content.Intent;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.Menu;
import android.view.MenuInflater;
import android.view.MenuItem;

public class Sudoku extends Activity implements OnClickListener {
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);

// Set up click listeners for all the buttons
View continueButton = findViewById(R.id.continue_button);
continueButton.setOnClickListener(this);
View newButton = findViewById(R.id.new_button);
newButton.setOnClickListener(this);
View aboutButton = findViewById(R.id.about_button);
aboutButton.setOnClickListener(this);
View exitButton = findViewById(R.id.exit_button);
exitButton.setOnClickListener(this);
}

public void onClick(View v) {
switch (v.getId()) {
case R.id.about_button:
Intent i = new Intent(this, About.class);
startActivity(i);
break;
// More buttons go here (if any) ...
}
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
super.onCreateOptionsMenu(menu);
MenuInflater inflater = getMenuInflater();
inflater.inflate(R.menu.menu, menu);
return true;
}


@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.settings:
startActivity(new Intent(this, Prefs.class));
return true;
// More items go here (if any) ...
}
return false;
}
}
