【问题描述】：

我需要设置/添加照片/电影作为 ToDo 应用的附件。 不幸的是： onActivityResult 行 super.onActivityResult(requestCode, resultCode, data);以红色突出显示，我收到错误消息：

“无法解析方法'onActivityResult(int, int, android.content.Intent)'”

AddActivity.java

    Button button_z = (Button) findViewById(R.id.button_z);

您的代码中缺少);。

Button button_z = (Button) findViewById(R.id.button_z);
button_z.setonclickListener(new View.onclickListener() 
    @Override
    public void onclick(View view2) 

        selectImage();
