android系统自带了apk安装成功后会发出一个广播，那么我们在activity上进行注册广播即可


@Override

protected void onStart() {

super.onStart();

IntentFilter intentFilter = new IntentFilter();

intentFilter.addAction(Intent.ACTION_PACKAGE_ADDED);

intentFilter.addDataScheme("package");

// 注册一个广播

registerReceiver(mBroadcastReceiver, intentFilter);

}



@Override

protected void onStop() {

// 解除广播

unregisterReceiver(mBroadcastReceiver);

super.onDestroy();

}



// 接收到安装完成apk的广播

private BroadcastReceiver mBroadcastReceiver= new BroadcastReceiver() {

@Override

public void onReceive(Context context, Intent intent) {

mVersionListAdapter.notifyDataSetChanged();//listview适配器进行刷新，读者可自己按照自己的需要进行更改自己的功能

}

};
