我在Android中使用Download Manager从特定网址下载图像和视频。
因此,当正在进行下载时,我正在显示一个简单的Progressbar
。
相反,我想显示自定义Progressbar,它显示下载内容的进度。这意味着它应该显示一个视图,以便用户可以知道下载了多少数据。
就像WhatsApp正在下载图像和视频一样。
感谢。

使用下面的代码显示下载百分比完成如下...
<ProgressBar
android:id="@+id/xml_reg_progressBar"
style="?android:attr/progressBarStyleHorizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginLeft="@dimen/common_left_right_margin"
android:layout_marginRight="@dimen/common_left_right_margin"
android:layout_marginTop="@dimen/reg_ph_linear_top_margin"
/>
并使用下面的代码来显示它......
protected static final int TIMER_RUNTIME = 180000; // in ms --> 10s
private ProgressBar progressTimer;
public void startTimer() {
final Thread timerThread = new Thread() {
@Override
public void run() {
mbActive = true;
try {
int waited = 0;
while (mbActive && (waited < TIMER_RUNTIME)) {
sleep(1000);
if (mbActive) {
waited += 1000;
updateProgress(waited);
}
}
} catch (InterruptedException e) {
// do nothing
} finally {
onContinue();
}
}
};
timerThread.start();
}
Handler handler = new Handler();
private void onContinue() {
handler.post(new Runnable() {
@Override
public void run() {
txtCallContactUsNumber
.setText(CommonVariable.CallForSupporMessage
+ contactInfo.MobileNo);
}
});
}
public void updateProgress(final int timePassed) {
if (null != progressTimer) {
// Ignore rounding error here
final int progress = progressTimer.getMax() * timePassed
/ TIMER_RUNTIME;
handler.post(new Runnable() {
@Override
public void run() {
Log.i("timePassed", "timePassed=" + timePassed);
DateFormat formatter = new SimpleDateFormat("mm:ss");
Calendar calendar = Calendar.getInstance();
calendar.setTimeInMillis(timePassed);
String timer = formatter.format(calendar.getTime());
formatter.setTimeZone(java.util.TimeZone.getTimeZone("GMT"));
txtTimerCount.setText(formatter.format(timePassed));
}
});
progressTimer.setProgress(progress);
}
}
在上面的代码中,这将调用1秒并且每1秒获得一次进度增量。
