先编写activity_main.xml文件
代码如下：
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:id="@+id/MyLayout"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<TextView
android:id="@+id/mytext"
android:text="北京魔乐科技软件学院"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
<Button
android:id="@+id/mybut"
android:text="删除"
android:layout_width="wrap_content"
android:layout_height="wrap_content"/>
</LinearLayout>
然后编写MainActivity类中的代码；
代码如下：
package com.example.myporject;
import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;
import android.os.Bundle;
import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.DialogInterface;
import android.text.method.HideReturnsTransformationMethod;
import android.text.method.PasswordTransformationMethod;
import android.view.Menu;
import android.view.View;
import android.view.View.OnClickListener;
import android.view.View.OnFocusChangeListener;
import android.view.View.OnLongClickListener;
import android.view.ViewGroup;
import android.view.WindowManager;
import android.widget.AdapterView;
import android.widget.AdapterView.OnItemSelectedListener;
import android.widget.ArrayAdapter;
import android.widget.Button;
import android.widget.CheckBox;
import android.widget.CompoundButton;
import android.widget.CompoundButton.OnCheckedChangeListener;
import android.widget.DatePicker;
import android.widget.DatePicker.OnDateChangedListener;
import android.widget.EditText;
import android.widget.ImageView;
import android.widget.LinearLayout;
import android.widget.ListView;
import android.widget.RadioButton;
import android.widget.RadioGroup;
import android.widget.SeekBar;
import android.widget.SimpleAdapter;
import android.widget.Spinner;
import android.widget.TextView;
import android.widget.TimePicker;
import android.widget.TimePicker.OnTimeChangedListener;
public class MainActivity extends Activity {
private Button mybut = null;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
this.mybut = (Button)super.findViewById(R.id.mybut);
this.mybut.setOnClickListener(new OnClickListenerlmpl());
}
private class OnClickListenerlmpl implements OnClickListener{
public void onClick(View v){
Dialog dialog =new AlertDialog.Builder(MainActivity.this).setIcon(R.drawable.logo).setTitle("确定删除").setMessage("您确定要删除该条信息吗")
.setPositiveButton("删除",new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
} ).setNeutralButton("查看详情", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
}).setNegativeButton("取消", new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
}).create();
dialog.show();
}
}
}
效果图如下：
