我的表单布局看起来像。

我希望在用户点击窗口时清除EditText的焦点,以便我实现下面的代码
/**
* Clear the edit text focus if the touch is outside its limits
*
* @param context the activity context
* @param editText the edit text
* @param event the motion event
*/
public static void clearEditTextFocusOnMontionEvent(@NonNull Context context, @NonNull EditText editText, @NonNull MotionEvent event) {
if (event.getAction() == MotionEvent.ACTION_DOWN) {
Rect outRect = new Rect();
editText.getGlobalVisibleRect(outRect);
if (!outRect.contains((int) event.getRawX(), (int) event.getRawY())) {
editText.clearFocus();
hideKeyboard(context, editText);
}
}
}
但重点不是每次都去LinearLayout。通过第一个可见的EditText获得焦点(当标题TextView可见时,例外,LinearLayout获得焦点)。
我预计LinearLayout总是可以获得焦点,因为它的可聚焦性是在theDescendants之前。
单击acionDone时也一样,我希望从当前的EditText中删除焦点,所以我实现了
if (actionId == EditorInfo.IME_ACTION_DONE) {
WindowsHelper.hideKeyboard(context, view);
view.clearFocus();
}
但是第一个可见的EditText再次获得了焦点。
有人知道我做错了吗?

在您的游戏中添加以下库
compile&#39; com.yinglan.keyboard:hidekeyboard:0.0.2&#39;
在onCreate方法中添加以下代码
HideUtil.init(本);
并且setFocus对您的父视图为true
