android:windowSoftInputMode="stateAlwaysVisible" - manifest文件中的>。

edittext.requestFocus ();-代码为>。

这将打开软键盘上的编辑文本有请求焦点作为活动出现。

只要在manifest文件中添加android:windowSoftInputMode="stateHidden"…

以下是我从Square得到的一个更可靠的解决方案:

fun View.focusAndShowKeyboard() { /** * This is to be called when the window already has focus. */ fun View.showTheKeyboardNow() { if (isFocused) { post { // We still post the call, just in case we are being notified of the windows focus // but InputMethodManager didn't get properly setup yet. val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager imm.showSoftInput(this, InputMethodManager.SHOW_IMPLICIT) } } } requestFocus() if (hasWindowFocus()) { // No need to wait for the window to get focus. showTheKeyboardNow() } else { // We need to wait until the window gets focus. viewTreeObserver.addOnWindowFocusChangeListener( object : ViewTreeObserver.OnWindowFocusChangeListener { override fun onWindowFocusChanged(hasFocus: Boolean) { // This notification will arrive just before the InputMethodManager gets set up. if (hasFocus) { this@focusAndShowKeyboard.showTheKeyboardNow() // It’s very important to remove this listener once we are done. viewTreeObserver.removeOnWindowFocusChangeListener(this) } } }) } }

代码从这里开始。

代码片段……

public void hideKeyboard(Context activityContext){

    InputMethodManager imm = (InputMethodManager)
            activityContext.getSystemService(Context.INPUT_METHOD_SERVICE);

    //android.R.id.content ( http://stackoverflow.com/a/12887919/2077479 )
    View rootView = ((Activity) activityContext)
            .findViewById(android.R.id.content).getRootView();

    imm.hideSoftInputFromWindow(rootView.getWindowToken(), 0);
}

public void showKeyboard(Context activityContext, final EditText editText){

    final InputMethodManager imm = (InputMethodManager)
            activityContext.getSystemService(Context.INPUT_METHOD_SERVICE);

    if (!editText.hasFocus()) {
        editText.requestFocus();
    }

    editText.post(new Runnable() {
        @Override
        public void run() {
            imm.showSoftInput(editText, InputMethodManager.SHOW_FORCED);
        }
    });
}

舱单内:

android:windowSoftInputMode="stateAlwaysVisible" -初始启动键盘。 android:windowSoftInputMode="stateAlwaysHidden" -初始隐藏键盘。

我也喜欢使用“adjustPan”，因为当键盘启动时，屏幕会自动调整。

 <activity
      android:name="YourActivity"
      android:windowSoftInputMode="stateAlwaysHidden|adjustPan"/>

final InputMethodManager keyboard = (InputMethodManager) ctx.getSystemService(Context.INPUT_METHOD_SERVICE);
keyboard.toggleSoftInput(InputMethodManager.SHOW_FORCED,0);
