安装动态创建界面踩坑记录

findViewbyId需要放在setContentView后面。不然会报错null

public Layout ChannelRack   
 protected void onCreate(Bundle savedInstanceState)
    {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
        //SlEngine.initEngine();
        setContentView(R.layout.activity_channel_rack);
        ChannelRack = findViewById(R.id.ChannelRack);
}
