问题描述

当我的带有 ScrollView 布局和 EditTexts 的 Activity 启动时，EditTexts 获得焦点并且 Android OnScreen 键盘打开.

When my Activity with a ScrollView layout and EditTexts starts, the EditTexts get focus and the Android OnScreen keyboard opens.

我怎样才能避免这种情况?

How I can avoid that?

当我在没有 ScrollView 的情况下使用 LinearLayout 和 RelativeLayout 时，它不会发生.

When I was using LinearLayout and RelativeLayout without the ScrollView it doesn't happen.

我已经尝试过这种方式，它可以工作，但这不是一个好方法:

I've tried it this way, and it works, but it's not a good way to do it:

TextView TextFocus = (TextView) findViewById(R.id.MovileLabel);
TextFocus.setFocusableInTouchMode(true);
TextFocus.requestFocus();

接下来你有一个我的一些布局的例子，当这个 Activity 启动时，焦点转到第一个 EditText，Description 并且 Android 键盘自动打开，这很烦人.

Next you have an example of some of my layouts with this problem, when this Activity starts, focus goes to the first EditText, Description and the Android keyboard opens automatically, this is very annoying.

推荐答案

如果你在Activity启动时有一个EditText焦点，Android会自动打开OnScreenKeyboard.

Android opens the OnScreenKeyboard automatically if you have an EditText focussed when the Activity starts.

您可以通过在 Activity 的 onCreate 方法中添加以下内容来防止这种情况发生.

You can prevent that by adding following into your Activity's onCreate method.

 getWindow().setSoftInputMode(
    WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
