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：

显示消息提示的对话框（例如：是否确认关闭）
简单列表对话框
单选列表对话框
多选列表对话框
自定义对标对话框
自定义View对话框

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(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

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：

最后给出 MainActivity的布局文件：

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