用于EditText领域的安卓键盘从数字切换到全键盘

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:inputType="number" />

EditText editText = findViewById(R.id.editText);
editText.setOnTouchListener(new View.OnTouchListener() {
    @Override
    public boolean onTouch(View v, MotionEvent event) {
        int inputType = editText.getInputType();
        if (inputType == InputType.TYPE_CLASS_NUMBER) {
            editText.setInputType(InputType.TYPE_CLASS_TEXT);
        } else {
            editText.setInputType(InputType.TYPE_CLASS_NUMBER);
        }
        return false;
    }
});
