本文介绍了安卓：如何跟踪如果软键盘openned？的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
在我的应用程序，设备软键盘覆盖EditTextViews，所以用户无法看到他是打字。
In my application, the device soft-keyboard is covering the EditTextViews, so user cannot see what he is typing.
所以，我想隐藏其他视图（如在我的情况下，一个按钮），使EditTextViews可见。
So i want to hide other Views(like a button in my case), to make the EditTextViews visible.
但在而不是做这样的事情。
But instead on doing something like
EditText.onFocus(){
//hide button
}
对于每个EditText上，我想要做类似
for every EditText, i want to do something like
if(soft-keyboard.isOpenned())
//hide button
}
如何跟踪如果软键盘openned还是关闭？
how to track if soft-keyboard is openned or closed?

推荐答案
有没有直接的方法找到它，但我想出了一个肮脏的解决方案，它做工精细。背后的想法是比较两种观点您的活动和键盘。高度
There is no direct way to find it, but i come up with a dirty solution and it work fine. The idea behind is to compare the height of two views your activity and keyboard.
boolean watcherState;
private void isShowing() {
final RelativeLayout relative = (RelativeLayout) findViewById(R.id.parent);
relative.getViewTreeObserver().addOnGlobalLayoutListener(
new OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
Rect r = new Rect();
// r will be populated with the coordinates of your view
// that area still visible.
relative.getWindowVisibleDisplayFrame(r);
int heightDiff = relative.getRootView().getHeight()
- (r.bottom - r.top);
Log.d("Height", heightDiff + "//");
if (heightDiff > 100) { // if more than 100 pixels, its
// probably a keyboard...
watcherState = true;
} else
watcherState = false;
}
});
}
