动态添加多个按钮

I want to add multiple buttons dynamically through the code on button click, I searched many previous posts which shows to add single button, but I need multiple ones.

我想通过按钮上的代码动态添加多个按钮点击，我搜索了很多以前显示添加单个按钮的帖子，但是我需要多个按钮。

Attached is the sample code.

附件是示例代码。

   public class MainActivity extends Activity {    @Override    public void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        Button b1 = (Button)findViewById(R.id.button1);        b1.setOnClickListener(new View.OnClickListener() {                  @Override            public void onClick(View v) {                               AddAll();                               }        });    }    public void AddAll() {        final RelativeLayout rl = (RelativeLayout)findViewById(R.id.rel);        final Button btn = new Button(this);        for(int i=0;i<4;i++)        {            rl.addView(btn);             btn.setText("hello");            btn.setWidth(320);            btn.setHeight(40);        }    }    @Override    public boolean onCreateOptionsMenu(Menu menu) {        getMenuInflater().inflate(R.menu.activity_main, menu);        return true;    }

Please help regarding the same. However adding single button is working fine, but I need to add many buttons one below the other.

请帮忙处理相同的事情。但是添加单个按钮是可以的，但是我需要在另一个按钮下面添加多个按钮。
