    </LinearLayout> 
    <ImageButton

     android:layout_height="match_parent" 
     android:background="@drawable/nav_forw" 
     android:contentDescription="@string/skx" /> 

</LinearLayout> 

Quelqu'un peut-il me aider à connaître la raison de ce problème et comment puis-je résoudre. Je suis un débutant à Android.

Merci

essayer cette

import android.os.Bundle; 
import android.app.Activity; 
import android.app.Dialog; 
import android.view.Menu; 
import android.view.View; 
import android.view.View.OnClickListener; 
import android.widget.Button; 

public class MainActivity extends Activity { 

@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(R.layout.activity_main); 

    Button bt_1 = (Button) findViewById(R.id.bt1); 
    bt_1.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View v) { 
      // TODO Auto-generated method stub 

      final Dialog dialog = new Dialog(MainActivity.this); 
      dialog.setContentView(R.layout.activity_popup); 
      dialog.setTitle("Hans Kelsen"); 

      //Her add your textView and ImageView if you want 

      Button dialogButton = (Button) dialog.findViewById(R.id.bt1_popUP); 
      // if button is clicked, close the custom dialog 
      dialogButton.setOnClickListener(new OnClickListener() { 
       @Override 
       public void onClick(View v) { 
       dialog.dismiss(); 
       } 
      }); 
      dialog.show(); 
     } 
     }); 

     // Same thing for bt_2 

    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
    // Inflate the menu; this adds items to the action bar if it is present. 
    getMenuInflater().inflate(R.menu.main, menu); 
    return true; 
    } 

}
