Android的Dialog选择框的实现

private void showSingleChoiceDialog(){
    final String[] items = { "01","02","03","04"};

    final AlertDialog.Builder singleChoiceDialog = new AlertDialog.Builder(MainActivity.this);
    singleChoiceDialog.setTitle("我是一个单选Dialog");
    // 第二个参数是默认选项，此处设置为0
    singleChoiceDialog.setSingleChoiceItems(items, 0,
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    mFishEyeMode = which;
                    MyLog.LOGI(TAG, "setSingleChoiceItems: mFishEyeMode="+mFishEyeMode);
                }
            });
    singleChoiceDialog.setPositiveButton("确定",
            new DialogInterface.OnClickListener() {
                @Override
                public void onClick(DialogInterface dialog, int which) {
                    if (mFishEyeMode == -1) {
                        mFishEyeMode = 0;
                    }
                        new Thread(){
                            @Override
                            public void run(){
                                InitFishEye();
                            }
                        }.start();
                    }

            });
    singleChoiceDialog.show();
}
