<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/mytext"

public class Hello extends Activity {
private Button btn = null;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState); // 生命周期方法
super.setContentView(R.layout.main); // 设置要使用的布局管理器
this.btn = (Button) super.findViewById(R.id.mybtn);
this.btn.setOnClickListener(new OnClickListernerImpl());
}
private class OnClickListernerImpl implements OnClickListener {
public void onClick(View v) {
Dialog dialog = new AlertDialog.Builder(Hello.this)
.setIcon(R.drawable.pic_m)
.setTitle("确定删除?")
.setMessage("您确定要删除此信息?")
.setPositiveButton("删除",
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface arg0,
int arg1) {
