private RateFrag rateFa;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
.
.
.
fragmentManager = getFragmentManager();
rateFa = (RateFrag) fragmentManager.findFragmentById(0);
.
.
.
}
@SuppressLint("HandlerLeak")
private Handler handler=new Handler(){
public void handleMessage(Message msg) {
camera.setOneShotPreviewCallback(MainActivity.this);
rateFa.view.invalidate();
};
};
直接通过fragmentManager 调用fragment中的view使用invalidate刷新会报错
求各位大神指点
