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
