Question

我点击关闭按钮时出现一个对话框，一切正常，但如果突然有人点击对话框的主体，应用程序将强行关闭

final Dialog dialog = new Dialog(context);
    dialog.setContentView(R.layout.activity_exit);
    dialog.setTitle("closing app");

    ImageView image = (ImageView) dialog.findViewById(R.id.id_exit_image);
    image.setImageResource(R.drawable.ic_launcher);

    Button dialogButtonyes = (Button) dialog.findViewById(R.id.id_exit_yes);
    Button dialogButtonno = (Button) dialog.findViewById(R.id.id_exit_no);
    dialogButtonyes.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.dismiss();
            finish();
        }
    });
    dialogButtonno.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View v) {
            dialog.dismiss();
        }
    });
    dialog.show();
};

错误在哪里？

Answer 1

在xml中声明单击处理程序方法时会引发异常，但该方法不存在于代码中。
