以上是新建一个class文件，最关键的自定义代码，以下就是在activity之中直接调用即可，中间用到的图片什么的，自己选好添加即可，
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final AlertDialog ad = new AlertDialog(MainActivity.this);
ad.setTitle("标题");
ad.setMessage("内容sdfs容内容内容内容内容内容内容");
ad.setPositiveButton("确定", new OnClickListener() {
@Override
public void onClick(View v) {
ad.dismiss();
Toast.makeText(MainActivity.this, "被点到确定", Toast.LENGTH_LONG)
.show();
}
});
ad.setNegativeButton("取消", new OnClickListener() {
@Override
public void onClick(View v) {
ad.dismiss();
Toast.makeText(MainActivity.this, "被点到取消", Toast.LENGTH_LONG)
.show();
}
});
}
}
