Question

I cant find whats wrong with my code I am getting cannot be resolved or is not a field on findViewById.

the problems lines are:

       playSeekBar = (ProgressBar) findViewById(R.id.progressBar1);
        buttonPlay = (Button) findViewById(R.id.buttonPlay);
         buttonStopPlay = (Button) findViewById(R.id.buttonStopPlay);

my xml code is:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android="http://schemas.android.com/apk/res/android"
 android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent">
<ProgressBar android:id="@+id/progressBar1" android:layout_width="wrap_content"    android:layout_height="wrap_content"></ProgressBar>
<Button android:text="Button" android:id="@+id/buttonPlay" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>
<Button android:text="Button" android:id="@+id/buttonStopPlay" android:layout_width="wrap_content" android:layout_height="wrap_content"></Button>

</LinearLayout>

my code is:

 public class radioActivite extends Activity implements OnClickListener {
 public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.radio_xml);




    initializeUIElements();

    initializeMediaPlayer();
}

private void initializeUIElements() {

       playSeekBar = (ProgressBar) findViewById(R.id.progressBar1);

    playSeekBar.setMax(100);
    playSeekBar.setVisibility(View.INVISIBLE);

    buttonPlay = (Button) findViewById(R.id.buttonPlay);
    buttonPlay.setOnClickListener(this);

    buttonStopPlay = (Button) findViewById(R.id.buttonStopPlay);

tried to clean the code but didn’t help me.
Thanks for the help!

Answer 1

Try removing your R.java so that it is regenerated. This is often Eclipse that does not see your changes in your res/ directory.
Another reason your R.java is not regenerated is you may have a problem in one of your resources (layout, styles, etc.)
