按下按钮时清除编辑文本焦点并隐藏键盘

Question

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.

I inserted these 2 lines of code in XML:

android:focusable="true"
android:focusableInTouchMode="true"

I also tried to add this in the button click method:

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.

Answer 1

To hide the keyboard call this:

InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
imm.hideSoftInputFromWindow(edittext.getWindowToken(), 0);

Answer 2

another solution is, create a dummy layout

<!-- 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

((LinearLayout) findViewById(R.id.dummy_id)).requestFocus();

Answer 3

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

You need to import android.view.inputmethod.InputMethodManager ;

The keyboard hides and clears the text when you click the button.

Answer 4

First you must disable the keyboard:

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:

view.clearFocus
