onBackPressed退出操作提示框  (退出程序写在主入口的结尾)

@Override
public void onBackPressed() {
//super.onBackPressed();
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setIcon(R.drawable.image1);
builder.setTitle("提示");
builder.setMessage("提示框内容");
builder.setPositiveButton("确定", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
builder.setNegativeButton("取消",null);
builder.show();
}
