本文实例总结了Android实现延迟的几种方法。分享给大家供大家参考，具体如下：
一、通过Thread
|
1

|
new Thread(){public void run(){sleep(***);}}.start(); |
通过ProgressDialog的使用来举例说明如下

public class A01Activity extends Activity { Button b; ProgressDialog pd; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); b=(Button)findViewById(R.id.b); b.setOnClickListener(new OnClickListener(){ @Override public void onClick(View v) { // TODO Auto-generated method stub final CharSequence dialogTitle=getString(R.string.dialogTitle); final CharSequence dialogBody=getString(R.string.dialogBody); pd=ProgressDialog.show(A01Activity.this, dialogTitle, dialogBody, true); new Thread(){ public void run(){ try { sleep(3000); } catch (InterruptedException e) { // TODO Auto-generated catch block e.printStackTrace(); } finally{ pd.dismiss(); } } }.start(); } }); }} |
二、通过Timer
|

3
4
5

|
TimerTask task = new TimerTask(){ public void run(){ //execute the task }};Timer timer = new Timer();timer.schedule(task, delay); |
三、
|

5
|
new Handler().postDelayed(new Runnable(){ public void run() { //execute the task } }, delay); |
四、利用AlarmManager
希望本文所述对大家Android程序设计有所帮助。
