关于按钮事件中执行Dialog报错的问题

Question

肯定报错startActivity(intent);这句话错了，要写Activity名。this。startActivity(intent);

Answer 1

改为这样：study_setting.this.startActivity(intent); 还不行
还没执行到句就报错了，对话框就不显示

Answer 2

Dialog dialog = new AlertDialog.Builder(study_setting.this)

Answer 3

study_setting类的开头能小写吗，eclipse没报错？

Answer 4

Dialog dialog = new AlertDialog.Builder(study_setting.this.getParent())
试试study_setting.this.getParent()

Answer 5

if(v==sp_voice_lib_import){
Dialog dialog = new AlertDialog.Builder(study_setting.this)
            .setIcon(R.drawable.dialog_icon)
            .setTitle("清空个人信息")
            .setMessage("确定要清空个人信息吗？")
            .setPositiveButton("确定", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                
                }
            })
            .setNegativeButton("取消", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int whichButton) {
                
                }
            }).create();
dialog.show();
}
还是不行，还报错
