主要方法：

setMessage()	设置对话框内容为简单文本
setItems()	对话款内容为简单列表项
setSingleChoiceItems()	对话框内容为单选列表项
setMultiChoiceItems()	对话款内容为多选列表项
setAdapter()	内容为自定义列表项
setView()	内容为自定义view

---

六种样式分析：

1. 显示消息提示的对话框（例如：是否确认关闭）
2. 简单列表对话框
3. 单选列表对话框
4. 多选列表对话框
5. 自定义对标对话框
6. 自定义View对话框
7.  

注：按钮的点击事件在 MainActivity 中声明 MainActivity的 XML 在文末给出

一、显示消息提示的对话框

效果：

实现方法：

建立 FirstService类 用于写静态方法

public class FirstService  extends MainActivity{
    public static void simple(View scource ){
        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.mMainActivity)
                .setTitle("你好呀~")//设置对话框 标题
                .setIcon(R.drawable.seek02)//设置图标
                .setMessage("the sentences you want to say");

        setPositiveButton(builder);//add 'yes' Button to AlertDialog
        setNegativeButton(builder)//add 'no' Button to AlertDialog
                .create()
                .show();
    }
    private static AlertDialog.Builder setPositiveButton(AlertDialog.Builder builder){
        // use 'setPositiveButton' method to add 'yes' Button
        return builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.mMainActivity,"you click 'yes' button ",Toast.LENGTH_SHORT).show();
            }
        });
    }

    private static AlertDialog.Builder setNegativeButton(AlertDialog.Builder builder){
        // use 'setPositiveButton' method to add 'yes' Button
        return builder.setNegativeButton("no", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.mMainActivity,"you click 'no' button ",Toast.LENGTH_SHORT).show();
            }
        });
    }
}

在MainActivity中调用该方法：

public class MainActivity extends Activity {
    public static MainActivity mMainActivity;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        mMainActivity = this;
    }
    public void send(View source){
        FirstService.simple(getWindow().getDecorView());
    }
}

---

二、列表项对话框

// 由于Dialog 本身原因 选完后 dialog会自动关闭 如果不想自动关闭，可以：不关闭方法

效果：

具体实现：

public class FirstService  extends MainActivity{
    private static String[] items = new String[]{
            "I believe I can fly",
            "Sunshine brightly",
            "I love study Java",
            "Wiw cool Dialog",
    };
    public static void simple(View scource ){
        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.mMainActivity)
                .setTitle("set your list Dialog's title here")//设置对话框 标题
                .setIcon(R.drawable.seek02)//设置图标
                .setItems(items, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(MainActivity.mMainActivity,"you click '" + items[which] + "' button ",Toast.LENGTH_SHORT).show();
                        return;
                    }
                });

        setPositiveButton(builder);//add 'yes' Button to AlertDialog
        setNegativeButton(builder)//add 'no' Button to AlertDialog
                .create()
                .show();
    }
    private static AlertDialog.Builder setPositiveButton(AlertDialog.Builder builder){
        // use 'setPositiveButton' method to add 'yes' Button
        return builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.mMainActivity,"you click 'yes' button ",Toast.LENGTH_SHORT).show();
            }
        });
    }

    private static AlertDialog.Builder setNegativeButton(AlertDialog.Builder builder){
        // use 'setPositiveButton' method to add 'yes' Button
        return builder.setNegativeButton("no", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.mMainActivity,"you click 'no' button ",Toast.LENGTH_SHORT).show();
                return;
            }
        });
    }
}

主活动中调用方法与（一）中类似，这里就不给出了了

三、单选列表对话框

具体调用方法：

public static void simple(View scource ){
        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.mMainActivity)
                .setTitle("单选列表对话框")//设置对话框 标题
                .setIcon(R.drawable.seek02)//设置图标
                .setSingleChoiceItems(items, 1, new DialogInterface.OnClickListener() {
                    @Override
                    public void onClick(DialogInterface dialog, int which) {
                        Toast.makeText(MainActivity.mMainActivity,"you click '" + items[which] + "' button ",Toast.LENGTH_SHORT).show();
                    }
                });

        setPositiveButton(builder);//add 'yes' Button to AlertDialog
        setNegativeButton(builder)//add 'no' Button to AlertDialog
                .create()
                .show();
    }

其他部分代码与 二 中相同，这里就不在给出

---

四、多选列表对话框

效果：

具体实现方法：

这里为了传送数据 判断用户选了哪些选项 setPositiveButton 进行了修改

public class FirstService  extends MainActivity{
    private static String[] items = new String[]{
            "I believe I can fly",
            "Sunshine brightly",
            "I love study Java",
            "Wiw cool Dialog",
    };
    private static boolean[] multiDialog = new boolean[]{false , true , false , true};
    public static void simple(View scource ){
        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.mMainActivity)
                .setTitle("单选列表对话框")//设置对话框 标题
                .setIcon(R.drawable.seek02)//设置图标
                .setMultiChoiceItems(items, multiDialog ,null);

        setPositiveButton(builder);//add 'yes' Button to AlertDialog
        setNegativeButton(builder)//add 'no' Button to AlertDialog
                .create()
                .show();
    }
    private static AlertDialog.Builder setPositiveButton(AlertDialog.Builder builder){
        // use 'setPositiveButton' method to add 'yes' Button
        return builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                for ( int i = 0 ; i < items.length ; i++ ){
                    if (multiDialog[i]){
                        Toast.makeText(MainActivity.mMainActivity,"you click '"  + items[i] +  "' button ",Toast.LENGTH_SHORT).show();
                    }
                }
            }
        });
    }

    private static AlertDialog.Builder setNegativeButton(AlertDialog.Builder builder){
        // use 'setPositiveButton' method to add 'yes' Button
        return builder.setNegativeButton("no", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.mMainActivity,"you click 'no' button ",Toast.LENGTH_SHORT).show();
                return;
            }
        });
    }
}

调用方法在 一 中给出 这里不在给出

五、自定义列表项对话框

效果：

简单实现：

public class FirstService  extends MainActivity{
    private static String[] items = new String[]{
            "I believe I can fly",
            "Sunshine brightly",
            "I love study Java",
            "Wiw cool Dialog",
    };
    public static void simple(View scource ){
        AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.mMainActivity)
                .setTitle("单选列表对话框")//设置对话框 标题
                .setIcon(R.drawable.seek02)//设置图标
                .setAdapter(new ArrayAdapter<String>(mMainActivity,R.layout.cell,items),null);

        setPositiveButton(builder);//add 'yes' Button to AlertDialog
        setNegativeButton(builder)//add 'no' Button to AlertDialog
                .create()
                .show();
    }
    private static AlertDialog.Builder setPositiveButton(AlertDialog.Builder builder){
        // use 'setPositiveButton' method to add 'yes' Button
        return builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.mMainActivity,"you click 'yes' button ",Toast.LENGTH_SHORT).show();
            }
        });
    }

    private static AlertDialog.Builder setNegativeButton(AlertDialog.Builder builder){
        // use 'setPositiveButton' method to add 'yes' Button
        return builder.setNegativeButton("no", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                Toast.makeText(MainActivity.mMainActivity,"you click 'no' button ",Toast.LENGTH_SHORT).show();
                return;
            }
        });
    }
}

附上 /layout/cell 布局文件

<?xml version="1.0" encoding="utf-8"?>
<TextView
    android:id="@+id/cell"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:textSize="15dp"
    android:orientation="vertical">
</TextView>

---

六、自定义 View 对话框

效果：

具体实现方法：

public class FirstService  extends MainActivity{
    private static TableLayout tableLayout;
    public static void simple(View scource ){
        tableLayout = (TableLayout) mMainActivity.getLayoutInflater().inflate(R.layout.cell,null);
        AlertDialog.Builder builder = new AlertDialog.Builder(mMainActivity)
                .setTitle("单选列表对话框")//设置对话框 标题
                .setIcon(R.drawable.seek02)//设置图标
                .setView(tableLayout);

        setPositiveButton(builder);//add 'yes' Button to AlertDialog
        setNegativeButton(builder)//add 'no' Button to AlertDialog
                .create()
                .show();
    }
    private static AlertDialog.Builder setPositiveButton(AlertDialog.Builder builder){
        // use 'setPositiveButton' method to add 'yes' Button
        return builder.setPositiveButton("yes", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                //do login operations here
                Toast.makeText(MainActivity.mMainActivity,"you info:" + tableLayout.toString(),Toast.LENGTH_SHORT).show();
            }
        });
    }

    private static AlertDialog.Builder setNegativeButton(AlertDialog.Builder builder){
        // use 'setPositiveButton' method to add 'yes' Button
        return builder.setNegativeButton("no", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialog, int which) {
                //do nothing here
                Toast.makeText(MainActivity.mMainActivity,"you click 'no' button ",Toast.LENGTH_SHORT).show();
            }
        });
    }
}

最后给出 cell.xml 布局：

<?xml version="1.0" encoding="utf-8"?>
<TableLayout
    android:id="@+id/cell"
    xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:orientation="vertical">
    <TableRow>
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="用户名"
            android:textSize="10pt"/>
        <!--Users can input personal info in here-->
        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="please input your account:"
            android:selectAllOnFocus="true"/>
        <!--if you set selectAllOnFocus 'true' your keyboard will open-->
    </TableRow>
    <TableRow>
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Code"
            android:textSize="10pt"/>
        <!--Users can input personal info in here-->
        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="please input your Code:"
            android:selectAllOnFocus="true"/>
    </TableRow>
    <TableRow>
        <TextView
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:text="Phone"
            android:textSize="10pt"/>
        <!--Users can input personal info in here-->
        <EditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:hint="please input your Phone number:"
            android:selectAllOnFocus="true"/>
    </TableRow>
</TableLayout>

---

最后给出 MainActivity的布局文件：

<?xml version="1.0" encoding="utf-8" ?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/idtatabHost"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_weight="1">
    <Button
        android:id="@+id/send"
        android:onClick="send"
        android:text="点我一下 有惊喜（吓） 。。。"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />
</LinearLayout>

可以看到 Button中 android:onClick="send"声明了 它的点击事件
