如何动态添加自定义Button
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);
}}
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);
