如何知道，如果键盘（DIS）将出现在Android的？ [英] How to know if keyboard (dis)appears in Android?

问题描述

我有一个EditText和想要的键盘出现时，给它更多的线路。
所以我要寻找像一个的OnKeyboardAppearsListener的，但无法找到它。
我想它一定存在，但可能以不同的方式...

I have an EditText and want to give it more lines when the keyboard appears. So i am looking for something like a "OnKeyboardAppearsListener" but can't find it. I think it must exist, but perhaps in a different way...

推荐答案

您需要的 @覆盖的 onConfigurationChanged 来能够处理运行时更改

You have to @Override onConfigurationChanged to be able to handle runtime changes:

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    // Checks whether a hardware or on-screen keyboard is available
    if (newConfig.keyboardHidden == Configuration.KEYBOARDHIDDEN_NO) {
        Toast.makeText(this, "Keyboard visible", Toast.LENGTH_SHORT).show();
    } else if (newConfig.keyboardHidden == Configuration.KEYBOARDHIDDEN_YES) {
        Toast.makeText(this, "Keyboard hidden", Toast.LENGTH_SHORT).show();
    }
}

从这里 拍摄的实施例。这里看看相关（其中包括）键盘字段，你可能需要使用。

编辑（RivieraKid）：改为考虑硬或屏幕键盘

Edit (RivieraKid): Changed to take account of hard or on-screen keyboard.
