Clear edittext focus and hide keyboard when button is pressed
提问by Guy
I'm making an app with edittext and a button. When I enter something into edittext and then click a button, I want the keyboard and focus on edittext to disappear but I can't seem to do it.
我正在制作一个带有编辑文本和按钮的应用程序。当我在edittext 中输入一些内容然后单击一个按钮时，我希望键盘和edittext 上的焦点消失，但我似乎无法做到。
I inserted these 2 lines of code in XML:
我在 XML 中插入了这两行代码：
android:focusable="true"
android:focusableInTouchMode="true"
I also tried to add this in the button click method:
我还尝试在按钮单击方法中添加它：
edittext.clearFocus();
this.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
And it just won't work, after I press the button, the keyboard remains there and edittext still has focus.
它只是不起作用，在我按下按钮后，键盘保持在那里并且 edittext 仍然具有焦点。

To hide the keyboard call this:
要隐藏键盘调用这个：
InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(edittext.getWindowToken(), 0);

another solution is, create a dummy layout
另一个解决方案是，创建一个虚拟布局
<!-- Dummy item for focus at startup -->
<LinearLayout
android:id="@+id/dummy_id"
android:orientation="vertical"
android:layout_width="0px"
android:layout_height="0px"
android:focusable="true"
android:focusableInTouchMode="true" />
and set the focus in your onButtonClickFunction
并将重点放在您的 onButtonClickFunction
((LinearLayout) findViewById(R.id.dummy_id)).requestFocus();

InputMethodManager inputManager = (InputMethodManager)
getSystemService(Context.INPUT_METHOD_SERVICE);
inputManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(),
InputMethodManager.HIDE_NOT_ALWAYS);
editText.setText("");
Add the following on your button onclick event
在您的按钮 onclick 事件中添加以下内容
You need to import android.view.inputmethod.InputMethodManager;
你需要import android.view.inputmethod.InputMethodManager;
The keyboard hides and clears the text when you click the button.
单击按钮时，键盘会隐藏和清除文本。

First you must disable the keyboard:
首先，您必须禁用键盘：
void hideKeyboard(Activity activity) {
View view = activity.getCurrentFocus();
InputMethodManager manager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
assert manager != null && view != null;
manager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}
void hideKeyboard(Activity activity) {
View view = activity.getCurrentFocus();
InputMethodManager manager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
assert manager != null && view != null;
manager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}
Second clear view (Layout, EditText...)focus:
第二个清晰的视图（布局、编辑文本...）焦点：
view.clearFocus
view.clearFocus
