Android Learning-ultra-simple implementation with progress ProgressBar scroll bar

Idea: Want to show percentage progress on ProgressBar, Baidu, Google search, full screen is that textprogressbar, I did not cite that, at that time feel should be easier to achieve, so directly on the UI to try, Put ProgressBar in the Relativelayout layout, and add a textview behind the ProgressBar, so that the two control overlay is resolved, the following is the XML, you can refer to ~

：

650) this.width=650; "title=" QQ picture 20150316150605.png "alt=" wkiol1ugghyrzq2zaabw3ffcjpa002.jpg "src="/http S3.51cto.com/wyfs02/m01/5b/52/wkiol1ugghyrzq2zaabw3ffcjpa002.jpg "/>

Xml:

<?xml version= "1.0"  encoding= "Utf-8"? ><linearlayout xmlns:android= "http// Schemas.android.com/apk/res/android "    android:layout_width=" Match_parent "     android:layout_height= "match_parent"     android:orientation= "Horizontal"       android:layout_gravity= "center"     android:background= "#FFFFFF" >            <TextView         android:id= "@+id/tvgraphtype"          Android:layout_width= "84DP"         android:layout_height= "wrap_content "        android:padding=" 2SP "         android:gravity= "Right"         android:maxlength= "6"         &nbSp;android:textcolor= "#666666"                     android:text= "Type"         android : textsize= "13SP"/>    <relativelayout                 android:layout_width= "Fill_parent"          android:layout_height= "Fill_parent"          android:orientation= "Vertical" >        <ProgressBar              android:id= "@+id/pbGraph"               style= "? android:attr/ Progressbarstylehorizontal "              Android:layout_width= "Match_parent"              android:layout_height= "Wrap_content"               android:gravity= "Right"               android:padding= "2SP"               android:progressdrawable= "@drawable/pbarcolor_out"                android:layout_marginleft= "4DP"              android:layout_marginright= "4DP"               android:layout_ Marginbottom= "4DP"/>        <textview              android:id= "@+id/tvgraphpercent"               android:layout_width= "Match_parent"               android:layout_height= "Wrap_content"               android:gravity= "Center"               android:textcolor= "#666666"                          android:text= "%"              android:textsize= "13sp"/>     </RelativeLayout>                 </LinearLayout>

The calculation of the percentage progress on the progress bar is also posted:

Pbouts is progressbar,outpercent is used to display percentages of TextView Holder.pbOuts.setMax (Graph.getround (maxout));   Holder.pbOuts.setProgress (Graph.getround (Outcomes));   if (maxout>0) {Holder.outPercent.setText (String.valueof (Graph.getround ((outcomes*100/maxout))) + "%");   }else {holder.outPercent.setText ("0%"); } holder.outPercent.bringToFront ();//The top is displayed when the control is superimposed, which is important
