Android(安卓)自动关闭的提示框

断断续续学安卓一个礼拜，发现Android对于Flex，在很多Widget的组件设计上还不是很人性化

经常以为应该具有的功能却不具备，而且Java GUI真的不是我的爱

比如AlertDialog的延时关闭，没有现成的方法或者组件，那么只能自己来扩展了

来吧，下面就是一个很勉强很勉强的装饰器模式

AutoCloseDialog

public class AutoCloseDialog{private AlertDialog dialog;private ScheduledExecutorService executor = Executors.newSingleThreadScheduledExecutor();public AutoCloseDialog(AlertDialog dialog){this.dialog = dialog;}public void show(long duration){//创建自动关闭任务Runnable runner = new Runnable() {@Overridepublic void run() {dialog.dismiss();}};//新建调度任务executor.schedule(runner, duration, TimeUnit.MILLISECONDS);dialog.show();}}

然后是演示代码

public class AlertExampleActivity extends Activity {// 声明Buttonprivate Button button;@Overridepublic void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.main);button = (Button) findViewById(R.id.button1);AlertDialog.Builder builder = new AlertDialog.Builder(this);final AlertDialog dialog = builder.setTitle("提示").setMessage("2秒后消失").create();final AutoCloseDialog d = new AutoCloseDialog(dialog);button.setOnClickListener(new View.OnClickListener() {@Overridepublic void onClick(View v) {d.show(2000);}});}}

layout就一个按钮，不用写出来了吧^_^

Best Regard to everybody!
