推荐答案

有几个步骤，你没有提到你知道多少对多少你不知道。

There are a few steps and you didn't mention how much you know versus how much you don't.

假设你的用户界面的初始结构定义在res /布局，它包括一个TextView的地方，在你的活动：

Assuming your UI initial structure is defined in the res/layout and it includes a TextView somewhere, in your activity:

public void updateTextView(String toThis) {

    TextView textView = (TextView) findViewById(R.id.textView);
    textView.setText(toThis);

    return;
}
