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
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
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
