如何强制重绘软键盘

How to force redraw of soft keyboard(如何强制重绘软键盘)

问题描述

我创建了一个自定义键盘，当方向改变时它不能正确调整大小.我试过 invalidateKeys()，并手动设置所有键的大小，但没有任何乐趣.

I created a custom keyboard which doesn't resize correctly when the orientation changes. I've tried invalidateKeys(), and manually setting the size of all of the keys, but no joy.

推荐答案

我在动态调整键盘视图的键高度时遇到了类似的问题.为了解决这个问题，我做了几件事:

I was having a simular problem with resizing my keyboardview's key height dynamically. To workaround the problem I did a couple of things:

1) 创建一个扩展键盘类的新类，该类定义公共 getKeyHeight 方法并覆盖 getHeight 方法.我的原型代码:

1) Create a new class that extends the Keyboard class that defines a public getKeyHeight method and overrides the getHeight method. My prototype code:

public void setKeyHeight(int height) {
   super.setKeyHeight(height);
}

@Override
public int getHeight() {
   return getKeyHeight() * 3;
}

2) 在我的

double height_modifier = 1.5;

int height = 0;
for(Keyboard.Key key : mKeyboard.getKeys()) {
   key.height *= height_modifier;
   key.y *= height_modifier;
   height = key.height;
}
mKeyboard.setKeyHeight(height);

我希望这会有所帮助...
