如何调用android源码系统的通知栏进度条

Question

如题所述

Answer 1

xml里
<ProgressBar
android:id="@+id/content_view_progress"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
style="@android:style/Widget.ProgressBar.Horizontal"
android:max="100"
android:layout_below="@id/content_view_image"
/>
代码里
private Handler handler = new Handler(){
@Override
public void handleMessage(Message msg) {
// TODO Auto-generated method stub
super.handleMessage(msg);
switch (msg.what) {
case 0:
notif.contentView.setProgressBar(R.id.content_view_progress, 100, len, false);
manager.notify(0, notif);

break;
case 1:
Toast.makeText(TestAndroid4Activity.this, "下载完成", 0).show();
break;
default:
break;
}
}

};
方法
private class DownLoadThread extends Thread{
private Timer timer = new Timer();
@Override
public void run() {
// TODO Auto-generated method stub
super.run();
timer.schedule(new TimerTask() {
@Override
public void run() {
// TODO Auto-generated method stub

Message msg = new Message();
msg.what = 0;
msg.obj = len;
handler.sendMessage(msg);

if(len == 100){
timer.cancel();
handler.sendEmptyMessage(1);
}

}
}, 0, 1000);
len = 0;
try {
while(len < 100){
len++;
Thread.sleep(1000);
}
} catch (InterruptedException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}

}
