Question

我有一个选择框并在视图中编辑文本。如果您对customNumberPicker进行长按，它将隐藏customNumberPicker并显示Edittext。（对编辑文本执行相同的操作）效果很好。

但是我也希望在切换到编辑文本模式时键盘可以打开。

这是我的代码

final NumberPicker numberPicker = (NumberPicker) dialog.findViewById(R.id.npWeight);
    final EditText editText = (EditText) dialog.findViewById(R.id.edWeight);

    numberPicker.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View view) {
            if (numberPicker.getVisibility() == View.VISIBLE) {
                editText.setVisibility(View.VISIBLE);
                numberPicker.setVisibility(View.GONE);
                editText.setFocusableInTouchMode(true);
                editText.requestFocus();
                showKeyboard(MyApplication.mainActivity);
            }

            return true;
        }
    });

    editText.setOnLongClickListener(new View.OnLongClickListener() {
        @Override
        public boolean onLongClick(View view) {
                editText.setVisibility(View.GONE);
                numberPicker.setVisibility(View.VISIBLE);
         //       hideKeyboard(MyApplication.mainActivity);
            return true;
        }
    });


private static void showKeyboard(Activity activity) {
        View view = activity.getCurrentFocus();
        InputMethodManager methodManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);
        assert methodManager != null && view != null;
        methodManager.showSoftInput(view, InputMethodManager.SHOW_IMPLICIT);
    }

尝试显示具有以下选项的键盘：

InputMethodManager inputMethodManager = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);                   

inputMethodManager.toggleSoftInputFromWindow(view.getApplicationWindowToken(),InputMethodManager.SHOW_FORCED, 0);

或

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

对于片段，请尝试以下代码：

public void showKeybarod(){
    new Handler().postDelayed(new Runnable() {
        @Override
        public void run() {
            if(getActivity() != null && !getActivity().isFinishing() && getUserVisibleHint()) {
                InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
                imm.showSoftInput(editText, InputMethodManager.SHOW_IMPLICIT);
            }
        }
    },300);
}

键盘未显示为edittext
