本文實例總結了Android實現延遲的幾種方法。分享給大家供大家參考，具體如下：
一、通過Thread

|
new Thread(){public void run(){sleep(***);}}.start(); |
通過ProgressDialog的使用來舉例說明如下

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、通過Timer

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

|
new Handler().postDelayed(new Runnable(){ public void run() { //execute the task } }, delay); |
四、利用AlarmManager
希望本文所述對大家Android程序設計有所幫助。
