onCreateJava生命周期中的view方法如何调用？

Question

当我想使用 setText 时遇到问题，但是当它直接在 onCreate 上调用时却不能？

这是我的方法：

    public void onSendData(View view) {
        long seek = videoView.getCurrentPosition();
        WritableMap args = Arguments.createMap();
        args.putInt("index", index);
        args.putInt("seek", (int) seek);
        args.putString("type", "paused");
        args.putString("name", playingVideo.getString("name"));
        args.putString("category_name", playingVideo.getString("category_name"));
        args.putString("date", playingVideo.getString("date"));
        sendEvent(reactContext, "onSendData", args);
        textName.setText(playingVideo.getString("name") + " " + playingVideo.getString("category_name"));
        textDate.setText(playingVideo.getString("date"));
        textCustomerName.setText(playingVideo.getString("customer_name"));
        textEstimate.setText(playingVideo.getString("estimate"));
        textPaid.setText(playingVideo.getString("paid"));
        textPrice.setText(playingVideo.getString("price"));
        textAddress.setText(playingVideo.getString("address"));
        textLongAddress.setText(playingVideo.getString("long_address"));


    }

这是我调用 onCreate 生命周期时的代码：

    public void onCreate() {
        super.onCreate();
        onSendData();
      ........
      .....
     }

请帮忙，非常感谢。

不确定到底是什么问题，但我会这样做：

public void onCreate() {
        super.onCreate();
        loadViews();       //create instance of view objects textName, textDate, etc. 
        onSendData(null);  //passing View as null 
      ........
      .....
     }

How do I call the view method in the onCreate Java lifecycle?
