在Android中动态更新TextView [英] dynamically update TextView in Android

问题描述

我对 Android 开发很陌生.有人可以让我知道动态更新 TextView (或整个屏幕)的相关 API 吗?

I am quite new to Android development. Can someone let me know the relevant APIs to dynamically update a TextView (or entire screen )?

例如:我有一个搜索应用程序，我需要在找到结果时显示结果，而不是等待所有结果然后显示.

For example: I have a search application and I need to show the results as they are found rather than waiting for all results and then show.

推荐答案

有几个步骤，你没有提到你知道多少与你不知道多少.

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

假设您的 UI 初始结构是在 res/layout 中定义的，并且它在您的活动中的某处包含一个 TextView:

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);
}
