在android中单击edittext时如何显示自定义键盘

我的应用程序中有一个自定义键盘。问题是当点击编辑文本时如何弹奏键盘。我使用setonfocuschangre监听器，现在，当edittext焦点改变时，custon键盘会出现。但我想在每次单击edittext时都显示此键盘。我忘记将edittext放在此处的一个信息位于片段中。

使用

onClickListener

如下所示：

edit_text.setOnClickListener(new OnClickListener(){

    @Override
    public void onClick(View v) {
        custom_keyboard.open();
    }
});

或者您可以这样做：

edit_text.setOnFocusChangeListener(new OnFocusChangeListener() {

        @Override
        public void onFocusChange(View v, boolean hasFocus) {
            if(hasFocus)
                custom_keyboard.open();
            else
                custom_keyboard.close();
        }
    });

使用

getWindow（）.setSoftInputMode（WindowManager.LayoutParams.SOFT\u INPUT\u STATE\u HIDDEN）

要禁用默认键盘，然后设置单击侦听器以显示您自己的键盘，可以尝试以下操作

    edittext.setOnClickListener(new OnClickListener() {
                    // NOTE By setting the on click listener, we can show the custom keyboard again,
                   // by tapping on an edit box that already had focus (but that had the keyboard hidden).
                    @Override public void onClick(View v) {
                        showCustomKeyboard(v);
                    }
          });


          // Disable standard keyboard hard way
          // NOTE There is also an easy way: 'edittext.setInputType(InputType.TYPE_NULL)' 
         // (but you will not have a cursor, and no 'edittext.setCursorVisible(true)' doesn't work )
                edittext.setOnTouchListener(new 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
                    }
                });


        // Disable spell check (hex strings look like words to Android)
        edittext.setInputType(edittext.getInputType() | InputType.TYPE_TEXT_FLAG_NO_SUGGESTIONS);

有关更多信息，请检查

我使用键盘标记在应用程序中创建了自定义键盘。我在屏幕上的一个相对窗口中添加了这个键盘

private void createCustomKeyboard() {
  Keyboard customKeyboard = new Keyboard(getActivity(), R.layout.keyboard);
  CustomKeyboard mCustomKeyboard = new CustomKeyboard(getActivity(), this);
  mCustomKeyboard.setKeyboard(customKeyboard);
  RelativeLayout relLayKeyboard.addView(mCustomKeyboard);  
} 

如果要在一个或多个EditText上使用此自定义键盘，则必须使用以下代码：

EditText edtxtName = (EditText) v.findViewById(R.id.edtName);
RelativeLayout relLayKeyboard = (RelativeLayout)findViewById(R.id.relLay_keyboard);
edtxtName.setOnTouchListener(exitSoftKeyBoard);

private final OnTouchListener exitSoftKeyBoard = new OnTouchListener() {

@Override
public boolean onTouch(View v, MotionEvent event) {
    InputMethodManager imm = (InputMethodManager) getActivity().getApplicationContext().getSystemService(
            android.content.Context.INPUT_METHOD_SERVICE);
    imm.hideSoftInputFromWindow(v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    if(v.equals(edtxtName)){
        edtxtName.requestFocus();
        relLayKeyboard.setVisibility(View.VISIBLE);
    } 
    return true;
  }
};

实际上，您可以为自定义键盘创建输入连接，然后将此连接设置为编辑文本

使用InputConnection，您的自定义键盘将取代android键盘并作为默认键盘工作。

您可以从这里获取代码：

在使用任何用户操作执行自定义键盘视图时，启动编辑文本的输入连接，并创建删除和输入文本的方法

在活动

onCreate

方法上声明

inputConnection

，如下所示

InputConnection inputConnection = editText.onCreateInputConnection(new EditorInfo());

当您输入任何文本时，请执行以下代码

inputConnection.commitText(text, 1);

if (TextUtils.isEmpty(inputConnection.getSelectedText(0))) {
    inputConnection.deleteSurroundingText(1, 0);
} else {
    inputConnection.commitText("", 1);
}

单击清除/退格按钮时，执行以下代码

inputConnection.commitText(text, 1);

if (TextUtils.isEmpty(inputConnection.getSelectedText(0))) {
    inputConnection.deleteSurroundingText(1, 0);
} else {
    inputConnection.commitText("", 1);
}

我将尝试这一点，以确保我忘记在这里放置的一个信息edittext在片段中..我使用onclicklistener来显示我的PopupleBoard，并在侦听器中隐藏键盘。谢谢你的帮助。。。。
