progress

I want to display a progress when the application start, then close progress when all data load completely. How can I do that? Use ProgressDialog to show Progress , Thread to load data and Handler to handle refresh UI . In onCreate, mProgressDlg = ProgressDialog.show(this, "App_Name", "Loading data...", true, false); new Thread(new Runnable(){ public void run() { /*Load Data*/ mProgressDlg.dismiss(); hRefresh.sendEmptyMessage(REFRESH); } }).start(); Handler hRefresh = new Handler(){ @Override public void handleMessage(Message msg) { switch(msg.what){ case REFRESH: /*Refresh UI*/ break; } } };

HTML5 introduced a new "progress" element that by default is rendered as a progress bar (thermometer). A very basic example is: <progress max="100" value="85"></progress> I have been experimenting with a variety of progress circle options using javascript, and also have been really impressed by some pure CSS approaches discussed here: CSS Progress Circle I am interested to know if anyone has successfully applied CSS to the "progress" element to provide a pie/clock/circle rendering rather than a linear display? EDIT/ADDENDUM: The "meter" element is also quite similar to "progress" but provides

效果图： 或 方法讲解： （1）invalidate()方法 invalidate()是用来刷新View的，必须是在UI线程中进行工作。比如在修改某个view的显示时， 调用invalidate()才能看到重新绘制的界面。invalidate()的调用是把之前的旧的view从主UI线程队列中pop掉。一般在自定义控件中会用到这个方法。 （2）RectF方法的应用 RectF是用来绘画矩形的方法。 RectF（left,top,right,bottom）,四个参数的含义分别是父控件距离矩形左上右下边距的距离，以下用图来说明： drawRoundRect方法是用来绘制圆角矩形的，它的参数如下： 参数说明 rect：RectF对象。 rx：x方向上的圆角半径。 ry：y方向上的圆角半径。 paint：绘制时所使用的画笔。 （3）onMeasure方法 指定自定义控件在屏幕上的大小,onMeasure方法的两个参数是由上一层控件 传入的大小，而且是模式和尺寸混合在一起的数值，需要MeasureSpec.getMode(widthMeasureSpec) 得到模式，MeasureSpec.getSize(widthMeasureSpec)得到尺寸。 onMeasure的几种模式分别为EXACTLY,AT_MOST,UNSPECIFIED。 [1]MeasureSpec.EXACTLY

I'm creating an updater that downloads application files using the Node module request . How can I use chunk.length to estimate the remaining file size? Here's part of my code: var file_url = 'http://foo.com/bar.zip'; var out = fs.createWriteStream('baz.zip'); var req = request({ method: 'GET', uri: file_url }); req.pipe(out); req.on('data', function (chunk) { console.log(chunk.length); }); req.on('end', function() { //Do something }); This should get you the total you want: req.on( 'response', function ( data ) { console.log( data.headers[ 'content-length' ] ); } ); I get a content length of

I want to show a progress Circle in my app while loading data. I have an activity and moving from one activity to another I am parsing some xml data so for the time being until the parsing is completed I want to show a circular loading effect. You can use an indeterminate ProgressBar for the circular loading effect. Here is how you do it in XML: <ProgressBar android:indeterminate="true" android:layout_width="50dp" android:layout_height="50dp" android:id="@+id/marker_progress" style="?android:attr/progressBarStyle" android:layout_gravity="center_vertical|center_horizontal"/> You can change the
