本文例項總結了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
