Android 只需要数字键盘，但也需要字母键盘

我只想为我的以下代码显示带有“完成”键的数字键盘，这样我就可以键入一个正常的整数或十进制数。但我得到的是一个带有“下一步”键的数字键盘。当按下“下一步”键时，它会移动到我不想要的字母键盘。我希望在插入值并按下Next（下一步）或Done（完成）键后，它直接移动到activity（活动）屏幕

在我的标签中，尝试以下操作：

EditText edit = (EditText)findViewById(R.id.editText1);
edit.setOnFocusChangeListener(new OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        ((EditText)v).setInputType(InputType.TYPE_NUMBER_FLAG_SIGNED | InputType.TYPE_NUMBER_FLAG_DECIMAL);
        }
    });

EditText edit = (EditText)findViewById(R.id.editText1);
edit.setOnFocusChangeListener(new OnFocusChangeListener() {

    @Override
    public void onFocusChange(View v, boolean hasFocus) {
        ((EditText)v).setInputType(InputType.TYPE_NUMBER_FLAG_SIGNED | InputType.TYPE_NUMBER_FLAG_DECIMAL);
        }
    });
