如何动态添加自定义Button

Gmonday 2013-12-01 10:48:14

不用在xml里面的配置
好比如下



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);

                    }}

但是如何添加自定义的button了？？

自定义button无非就是设置背景，设置大小等.

ViewGroup.LayoutParams params = new ViewGroup.LayoutParams(
                            ViewGroup.LayoutParams.WRAP_CONTENT,
                            ViewGroup.LayoutParams.WRAP_CONTENT);
        bt1.setBackgroundResource(R.drawable.xx);
        bt1.setGravity(Gravity.CENTER);
        layout2.addView(root, params);

楼主把第一句setContentView(layout2);删了
