更改后，您必须将活动更改为ActivityGroup

tabhostku.setup();

到

试试这个

变,

tabhostku.setup();

到

在

onPause

和

onResume

中添加以下代码

@Override
public void onPause() {
    super.onPause();
    try {
        mlam.dispatchPause(isFinishing());
    } catch (Exception e) {}
}

@Override
public void onResume() {
    super.onResume();
    try {
        mlam.dispatchResume();
    } catch (Exception e) {}
}
