图一效果具体代码
main.xml布局配置
<Button
android:id="@+id/idButtonDialog1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Dialog1"
android:onClick="clickButtonDialog1"

Activity代码
/**
* 重载当前Activity的[键盘按下]事件处理方法.
*/
public boolean onKeyDown(int keyCode, KeyEvent event) {
//KeyEvent.KEYCODE_BACK:键盘上的[back]按键
//捕获按键：按下[back]键并且没有重复
if (keyCode == KeyEvent.KEYCODE_BACK && event.getRepeatCount() == 0) {
showDialog1();
}
return false;
}
public void clickButtonDialog1(View v){
showDialog1();
}
public void showDialog1(){
AlertDialog.Builder builder = new Builder(this)
.setMessage("确认退出吗？")//设置对话框内容
.setTitle("提示")//设置对话框标题
.setPositiveButton("确定", new OnClickListener() {//设置对话框[肯定]按钮
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();//关闭对话框
finish();//结束当前Activity
}
})
.setNegativeButton("取消", new OnClickListener() {//设置对话框[否定]按钮
@Override
public void onClick(DialogInterface dialog, int which) {
dialog.dismiss();//关闭对话框
}
});
builder.create().show();//创建对话框并且显示该对话框

android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Dialog5"
android:onClick="clickButtonDialog5"
/>
Activity代码
public void clickButtonDialog5(View v){
showDialog5();
}
public void showDialog5(){
final Context context = this;
//定义复选框选项
String[] multiChoiceItems = {"Item1","Item2"};
boolean[] defaultSelectedStatus = {false,true};//复选框默认值：false=未选;true=选中
//创建对话框
new AlertDialog.Builder(context)
.setTitle("复选框")//设置对话框标题
.setMultiChoiceItems(multiChoiceItems, defaultSelectedStatus, new OnMultiChoiceClickListener(){
@Override
public void onClick(DialogInterface dialog, int which,
boolean isChecked) {
Toast.makeText(context, "Item"+which+"'s status is "+isChecked+".", Toast.LENGTH_LONG).show();
}
})
.setPositiveButton("确定", null)//设置对话框[肯定]按钮
.setNegativeButton("取消", null)//设置对话框[否定]按钮
.show();
}
图六效果具体代码
main.xml布局配置
<Button
android:id="@+id/idButtonDialog6"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Dialog6"
android:onClick="clickButtonDialog6"
/>
Activity代码
public void clickButtonDialog6(View v){
showDialog6();
}
public void showDialog6(){
final Context context = this;
//定义列表选项
String[] items = {"Item1","Item2"};
//创建对话框
new AlertDialog.Builder(context)
.setTitle("列表")//设置对话框标题
.setItems(items, new OnClickListener(){
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(context, "Item is "+which+".", Toast.LENGTH_LONG).show();
}
})
.setNegativeButton("取消", new OnClickListener(){
@Override
public void onClick(DialogInterface dialog, int which) {
Toast.makeText(context, "Button is "+which+" click.", Toast.LENGTH_LONG).show();
}
})//设置对话框[否定]按钮
.show();
}
图七效果具体代码
main.xml布局配置
<Button
android:id="@+id/idButtonDialog7"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Dialog7"
android:onClick="clickButtonDialog7"
/>
另外需要布局配置文件 main_dialog_custom.xml ，内容：
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="horizontal"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:id="@+id/customDialog"
>
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="姓名："
/>
<EditText
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text=""
android:minWidth="200dip"
android:id="@+id/dialogCustomEditTextUserName"
/>
</LinearLayout>
Activity代码
public void clickButtonDialog7(View v){
showDialog7();
}
public void showDialog7(){
final Context context = this;
//初始化自定义布局参数
LayoutInflater layoutInflater = getLayoutInflater();
//为了能在下面的OnClickListener中获取布局上组件的数据，必须定义为final类型.
final View customLayout = layoutInflater.inflate(R.layout.main_dialog_custom, (ViewGroup)findViewById(R.id.customDialog));
//创建对话框
new AlertDialog.Builder(context)
.setTitle("自定义布局")//设置对话框标题
.setView(customLayout)//为对话框添加组件
.setPositiveButton("确定", new OnClickListener(){
@Override
public void onClick(DialogInterface dialog, int which) {
//获取自定义布局上的输入框的值
EditText customDialogUserName = (EditText)customLayout.findViewById(R.id.dialogCustomEditTextUserName);
Toast.makeText(context, "姓名="+customDialogUserName.getText().toString(), Toast.LENGTH_SHORT).show();
}
})//设置对话框[肯定]按钮
.setNegativeButton("取消", null)//设置对话框[否定]按钮
.show();
}
图八效果具体代码
说明：图八和图七理论上一样的，都是自定义布局对话框。不过，图八方式可以用来替换手机的系统选项菜单风格。
main.xml配置
<Button
android:id="@+id/idButtonDialog8"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Dialog8"
android:onClick="clickButtonDialog8"
/>
menu_gridview.xml配置
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<GridView
android:id="@+id/gridview"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:numColumns="4"
android:verticalSpacing="10dip"
android:horizontalSpacing="10dip"
android:stretchMode="columnWidth"
android:gravity="center"
/>
</LinearLayout>menu_item.xml配置
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@+id/RelativeLayout_Item"
android:layout_width="fill_parent" android:layout_height="wrap_content"
android:paddingBottom="5dip"
>
<ImageView
android:id="@+id/item_image"
android:layout_centerHorizontal="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
<TextView
android:layout_below="@id/item_image"
android:id="@+id/item_text"
android:layout_centerHorizontal="true"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>
</RelativeLayout>
