Android 动态添加Button(1)

这是一个非常简单的动态添加Button的例子：

package com.kkkk.llll;

import android.app.Activity;
import android.os.Bundle;
import android.widget.Button;
import android.widget.LinearLayout;

public class AddButton extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        //setContentView(R.layout.main);
        final LinearLayout layout2 = new LinearLayout(this);
        layout2.setOrientation(LinearLayout.VERTICAL);
        Button bt1 = new Button(this);
        setContentView(layout2);
        Button bt2 = new Button(this);
        bt1.setText("按钮1");
        bt2.setText("按钮2");      
       layout2.addView(bt1);
       layout2.addView(bt2);
       setContentView(layout2);
        
        
    }
}

XML文件里面不需要进行任何配置。
