答案 0 :(得分：1)

我有答案：

我使用过该代码：

public void onClick(View v) {
    if(v.getId() == R.id.xCBApple){      
            Toast.makeText(CheckBoxClass.this,"Apple is Chedked",Toast.LENGTH_SHORT);
    }
    if(jBackButton.performClick())
    {
            Intent intent = new Intent(CheckBoxClass.this,AndroidWidgetsActivity.class);
            startActivity(intent);
    }
}

但我必须使用v.getId（）== R.id.backButton而不是jBackButton.performClick（）并且错误消失了但我不知道有关performClick（），任何人都可以知道吗？
