我想在EditText被聚焦时自动显示软键盘(如果设备没有物理键盘),我有两个问题:

当我的活动显示时,我的EditText是集中的,但键盘不显示,我需要再次单击它来显示键盘(它应该显示时,我的活动显示)。 当我在键盘上点击完成时,键盘被解散,但EditText保持集中,我不想(因为我的编辑已经完成)。

继续说,我的问题是有一些更像iPhone的东西:保持键盘与我的EditText状态同步(聚焦/不聚焦),当然,如果有物理键盘,也不会呈现软键盘。

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

这对我很管用。你也可以尝试用这个来显示键盘:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

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。

对于Kotlin,只需使用以下扩展:

fun EditText.showKeyboard() {
    val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.showSoftInput(this, InputMethodManager.SHOW_IMPLICIT)
}

fun EditText.hideKeyboard() {
    val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(this.windowToken, 0)
}

我同意raukodraug的观点,在swithview中使用时,你必须像这样请求/清除焦点:

    final ViewSwitcher viewSwitcher = (ViewSwitcher) findViewById(R.id.viewSwitcher);
    final View btn = viewSwitcher.findViewById(R.id.address_btn);
    final View title = viewSwitcher.findViewById(R.id.address_value);

    title.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            viewSwitcher.showPrevious();
            btn.requestFocus();
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.showSoftInput(btn, InputMethodManager.SHOW_IMPLICIT);
        }
    });

    // EditText affiche le titre evenement click
    btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            btn.clearFocus();
            viewSwitcher.showNext();
            InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
            imm.hideSoftInputFromWindow(btn.getWindowToken(), 0);
            // Enregistre l'adresse.
            addAddress(view);
        }
    });

的问候。

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