项目中用到WebView加上进度条放在顶部,让用户知道加载进度情况,可以提高用户体验:
效果:
布局:
android:layout_
android:layout_
android:orientation="vertical">
android:id="@+id/webView"
android:layout_
android:layout_
android:layout_below="@+id/toolbar_container" />
android:id="@+id/progressBar"
android:layout_
android:layout_
android:layout_below="@+id/toolbar_container"
android:background="@drawable/crowd_progressbar_unselect" />
进度条样式:
进度图片:
-
android:id="@android:id/progress" >
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);
}
}
