main.xml代码下:
<?xml version="1.0" encoding="utf-8"?> <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" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <Button android:id="@+id/mybtn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="删除" /> </LinearLayout>
.java代码如下:
package org.lxh.demo; import android.app.Activity; import android.app.AlertDialog; import android.app.Dialog; import android.content.DialogInterface; import android.os.Bundle; import android.view.View; import android.view.View.OnClickListener; import android.view.View.OnFocusChangeListener; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; 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) { } }) .setNegativeButton("取消", new DialogInterface.OnClickListener() { public void onClick(DialogInterface arg0, int arg1) { } }).create(); dialog.show(); } } }
