VideoView zeigt das Video beim Wechseln der Registerkarten nicht an

Question

Ich habe 2 Registerkarten, die jeweils videoView enthalten. Aber wenn ich auf die zweite Registerkarte wechsle, spielt das Video, das Audio funktioniert, aber das Video wird nicht abgespielt und die Ansicht ist nur schwarz. Dies funktioniert gut in Android 2.1 +, aber es does 't in 1,6 Hier ist mein Code:

TabActivity:

package com.example.tab; 


import android.app.TabActivity; 
import android.content.Intent; 
import android.os.Bundle; 
import android.widget.TabHost; 

public class main extends TabActivity { 
    /** Called when the activity is first created. */ 

private TabHost tabHost; 

public void onCreate(Bundle savedInstanceState){ 
super.onCreate(savedInstanceState); 
tabHost = getTabHost(); 

    Intent intent1 = new Intent(this, Video1.class); 
    Intent intent2 = new Intent(this, Video2.class); 


    tabHost.addTab(tabHost.newTabSpec("Tab1") 
     .setIndicator("Video1") 
     .setContent(intent1.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP))); 

    tabHost.addTab(tabHost.newTabSpec("Tab2") 
    .setIndicator("Video2") 
    .setContent(intent2.addFlags(Intent.FLAG_ACTIVITY_SINGLE_TOP))); 

} 
}
