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。

要强制显示软键盘,可以使用

EditText yourEditText= (EditText) findViewById(R.id.yourEditText);
yourEditText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(yourEditText, InputMethodManager.SHOW_IMPLICIT);

为了移除EditText上的焦点,你需要一个虚拟视图来抓取焦点。


关闭它,你可以使用

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

这适用于在对话框中使用它

public void showKeyboard(){
    InputMethodManager inputMethodManager = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
    inputMethodManager.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
}

public void closeKeyboard(){
    InputMethodManager inputMethodManager = (InputMethodManager) context.getSystemService(Context.INPUT_METHOD_SERVICE);
    inputMethodManager.toggleSoftInput(InputMethodManager.HIDE_IMPLICIT_ONLY, 0);
}

其他回答

editText.post(new Runnable() {
    @Override
    public void run() {
        InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
    }
});

这很疯狂,但确实有效

fun showKeyboard(view: View) {
    try {
        InputMethodManager::class.java.getMethod(
                "showSoftInputUnchecked",
                Int::class.javaPrimitiveType,
                ResultReceiver::class.java
        ).apply {
            isAccessible = true
            invoke(view.context.inputMethodManager, 0, null)
        }
    }
    catch (e: Exception) {
       e.printStackTrace()
    }
}

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。

对于片段,肯定它的工作:

 displayName = (EditText) view.findViewById(R.id.displayName);
    InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
    imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);

要强制显示软键盘,可以使用

EditText yourEditText= (EditText) findViewById(R.id.yourEditText);
yourEditText.requestFocus();
InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
imm.showSoftInput(yourEditText, InputMethodManager.SHOW_IMPLICIT);
