AlertDialog之常见对话框（单选对话框、多选对话框、进度条对话框）

单选对话框，顾名思义就是只能选一项（setSingleChoiceItems(Items,)）

public void click(View v){
        //创建对话框类
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        //定义item选项
        final String items[] = new String[]{"一只","两只","三只"};
        builder.setTitle("没有什么事是一只口红解决不了的，如果有那就两只")//设置标题
                .setSingleChoiceItems(items,-1, new DialogInterface.OnClickListener() {//设置单选
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i) {
                        Toast.makeText(MainActivity.this,"你选择了用"+items[i]+"口红解决问题",Toast.LENGTH_SHORT).show();
                }
                }).setPositiveButton("是的", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                Toast.makeText(MainActivity.this,"我选择了是",Toast.LENGTH_SHORT).show();
            }
        }).setNegativeButton("取消", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {
                Toast.makeText(MainActivity.this,"我选择了取消，因为我相信口红解决不了",Toast.LENGTH_SHORT).show();
            }
        }).show();
    }

 下面是多选对话框

public void click1(View v){
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        final String items[] = {"First","Second","Thrid","Fourth"};
        final boolean boo[] = {true,false,false,false};

        builder.setTitle("人生有多种选择")
                .setMultiChoiceItems(items, boo, new DialogInterface.OnMultiChoiceClickListener() {
                    @Override
                    public void onClick(DialogInterface dialogInterface, int i, boolean b) {
                      
                    }
                }).setPositiveButton("确定", new DialogInterface.OnClickListener() {
            @Override
            public void onClick(DialogInterface dialogInterface, int i) {

            }
        }).show();
    }

单选是setSingleChoiceItems()，多选是setMultiChoiceItems()，

进度条对话框

public void click2(View v){
        final ProgressDialog pd = new ProgressDialog(this);
        pd.setTitle("加载");
        pd.setProgress(0);
        pd.setMax(10);
        pd.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
        pd.show();
        new Thread(){
            @Override
            public void run() {
                super.run();
                for (int i=0; i<=10; i++){
                    pd.setProgress(i);
                    try {
                        Thread.sleep(1000);
                    } catch (InterruptedException e) {
                        e.printStackTrace();
                    }
                }
            }
        }.start();
    }
