Entry获得焦点时隐藏键盘

情况

我有一个使用外部键盘的Android应用,想要在root控件获得焦点时隐藏软键盘。

参考

this android documentation之后,它声明了以下内容:

  

注意:如果用户的设备连接了硬件键盘,则不会出现软输入法。

但是,在某些Android设备中,当Entry获得焦点时,软输入会出现

如何在这些情况下隐藏软输入?

您可以使用此代码隐藏软键盘

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

获取EditText的实例

EditText editText = (EditText) findViewById(R.id.edittext);

要防止Default SoftKeyboard出现在EditText中,请覆盖以下事件

//显示自定义键盘

    edittext.setOnFocusChangeListener(new View.OnFocusChangeListener() {
        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if (hasFocus) showCustomKeyboard(v);
            else hideCustomKeyboard();
        }
    });
    edittext.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            showCustomKeyboard(v);
        }
    });
    edittext.setOnTouchListener(new View.OnTouchListener() {
        @Override
        public boolean onTouch(View v, MotionEvent event) {
            EditText edittext = (EditText) v;
            int inType = edittext.getInputType();       // Backup the input type
            edittext.setInputType(InputType.TYPE_NULL); // Disable standard keyboard
            edittext.onTouchEvent(event);               // Call native handler
            edittext.setInputType(inType);              // Restore input type
            return true; // Consume touch event
        }
    });
}
public void hideCustomKeyboard() {
    keyboardView.setVisibility(View.GONE);
    keyboardView.setEnabled(false);
}
public void showCustomKeyboard( View v) {
    keyboardView.setVisibility(View.VISIBLE);
    keyboardView.setEnabled(true);
    if( v!=null ){
        ((InputMethodManager)getSystemService(Activity.INPUT_METHOD_SERVICE)).hideSoftInputFromWindow(v.getWindowToken(), 0);
    }
}
public boolean isCustomKeyboardVisible() {
    return keyboardView.getVisibility() == View.VISIBLE;
}
@Override public void onBackPressed() {
    if( isCustomKeyboardVisible() ) hideCustomKeyboard(); else this.finish();
}

这对我有用:

public static void DisableSoftKeyboard (EditText editText)
{
    ((InputMethodManager)GetSystemService(Context.InputMethodService)).HideSoftInputFromWindow(editText.WindowToken, 0);
    if (Build.VERSION.SdkInt >= BuildVersionCodes.Honeycomb) {
        editText.SetRawInputType (InputTypes.ClassText);
        editText.SetTextIsSelectable (true);
    } else {
        editText.SetRawInputType (InputTypes.Null);
        editText.Focusable = true;
    }
}

实施:

editText.FocusChange+= (sender, e) => {
    DisableSoftKeyboard(editText);
};
