Arc*_*pgc 6 android android-softkeyboard android-edittext
在我的应用程序中,设备软键盘覆盖了EditTextViews,因此用户无法看到他正在键入的内容.
所以我想隐藏其他视图(就像我的情况下的一个按钮),以使EditTextViews可见.
而是做了类似的事情
EditText.onFocus(){
//hide button
}
对于每个EditText,我想做类似的事情
if(soft-keyboard.isOpenned())
//hide button
}
如何打开或关闭软键盘？

其实我的布局是这样的:

当我在输入文字的问题出现EditTextViews在ScrollView
没有直接的方法来找到它,但我提出了一个肮脏的解决方案,它工作正常.背后的想法是比较您的活动和键盘的两个视图的高度.
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;
}
});
}
