布局:
<relativelayout android:layout_width="match_parent" android:layout_height="match_parent" android:orientation="vertical"> <webview android:id="@+id/webview" android:layout_width="match_parent" android:layout_height="match_parent" android:layout_below="@+id/toolbar_container" /> <progressbar android:id="@+id/progressbar" style="@style/crowd_item_progressbar" android:layout_width="match_parent" android:layout_height="3dp" android:layout_below="@+id/toolbar_container" android:background="@drawable/crowd_progressbar_unselect" /> </relativelayout>
进度条样式:
<style name="crowd_item_progressbar"> <item name="android:indeterminateonly">false</item> <item name="android:progressdrawable">@drawable/crowd_progressbar_background</item> <item name="android:minheight">10dp</item> <item name="android:maxheight">10dp</item> </style>
进度图片:
<layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item android:id="@android:id/progress" > <clip> <shape> <solid android:color="@color/selected"/> <!--<corners android:radius="1.5dp"/>--> </shape> </clip> </item> </layer-list>
代码:
public class webchromeclient extends android.webkit.webchromeclient { @override public void onprogresschanged(webview view, int newprogress) { if (newprogress == 100) { mprogressbar.setvisibility(gone); } else { if (mprogressbar.getvisibility() == gone) mprogressbar.setvisibility(visible); mprogressbar.setprogress(newprogress); } super.onprogresschanged(view, newprogress); } } @override protected void onscrollchanged(int l, int t, int oldl, int oldt) { layoutparams lp = (layoutparams) mprogressbar.getlayoutparams(); lp.x = l; lp.y = t; mprogressbar.setlayoutparams(lp); super.onscrollchanged(l, t, oldl, oldt); } }
