Hallo Leute
Ich bins schon wieder^^, diesmal mit der Frage wie ich meine View Klasse in meiner Activity aufrufen kann. Ich habe eine Activity die beim drücken des Knopfes: Neues Feld aufgerufen wird, diese Activity wird dann geöffnet und beinhaltet das Layout: Feldlayout. Nun hab ich eine View-kLasse: ViewFeld die in der FeldLayout-Activity geöffnet werden soll, um benutzt zu werden.
Kann mir jemand sagen wie ich das machen kann oder mir einen Tipp geben was ich dafür benötige?
Feldlayout.class

import android.widget.Button;
public class feldlayout extends Activity{
Button b7;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.feldlayout);
b7 = (Button) findViewById(R.id.button7);
b7.setOnClickListener(handler);
}
View.OnClickListener handler = new View.OnClickListener(){
public void onClick(View v) {
if(v==b7){
Intent i = new Intent(feldlayout.this, Main_Layout.class);
startActivity(i);
}
}};}Feldlayout.xml
