取消和确定对话框的创建:

AlterDialog 对话框 用的API AlterDialog.Builder builder = new Builder( Contex contex);

第一步：创建一个按钮触发事件 layout 布局

思路：

取消确认对话框 建立时需要建立

1、Alert

<RelativeLayout
xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
>
<Button
android:id="@+id/b"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="确定取消对话框"
android:onClick="click"
android:layout_centerHorizontal="true"

/>
</RelativeLayout>

}

public void click(View v) {
AlertDialog.Builder builder = new Builder(this);  //创建对话框的Builder 对象

builder.setIcon(android.R.drawable.alert_light_frame);
builder.setTitle("删除后将无法恢复");
builder.setMessage("你确定删除了吗亲");
// 设置确认按钮
builder.setPositiveButton("确认", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {

Toast.makeText(MainActivity.this, "再见了哥们会想你的", 0).show();
}
});

// 设置取消按钮
builder.setNegativeButton("取消", new OnClickListener() {

@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
Toast.makeText(MainActivity.this, "好的亲", Toast.LENGTH_SHORT).show();
}
});
builder.show();
}
