Taste ändert das Layout beim Start Emulator

Question

This is what it shows on the emulator

This is how it is on the Layout

Wann immer ich starten Sie den Emulator, um die Größe und die Positionierung der Tasten alle ändern .. Weiß jemand, warum dies geschieht? Ich bin ziemlich neu, also bin ich mir ziemlich sicher, dass ich hier ein paar Fehler mache. Würde etwas Hilfe lieben, lassen Sie mich wissen

Dies ist mein Code:

public class MainActivity extends Activity { 
    private static Button button_sbm; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 
     OnClickButtonListener(); 
    } 

     public void OnClickButtonListener() { 
      button_sbm = (Button)findViewById(R.id.button2); 
      button_sbm.setOnClickListener(
        new View.OnClickListener() { 
         @Override 
        public void onClick(View v) { 
         Uri uri = Uri.parse("http://google.com/"); 

         Intent intent = new Intent(Intent.ACTION_VIEW, uri); 
         startActivity(intent);

Answer 2

Antwort auf die Frage nach dem Onclick:

Sie ein Onclick-Attribut, um Ihre Schaltflächen setzen sollte:

<Button 
     android:id="@+id/button2" 
     style="?android:attr/buttonStyleSmall" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:layout_above="@+id/button9" 
     android:layout_alignLeft="@+id/button10" 
     android:layout_marginBottom="20dp" 
     android:onclick="button2click" 
     android:text="Nieuws" /> 

und tun, wie dies in Ihrem Java:

public class MainActivity extends Activity { 
    private static Button button_sbm; 
    @Override 
    protected void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 
     setContentView(R.layout.activity_main); 


    } 

    public void button2click (View v) 
     { 
      Uri uri = Uri.parse("http://google.com/"); 

      Intent intent = new Intent(Intent.ACTION_VIEW, uri); 
      startActivity(intent); 
     } 
}
