webview添加仿微信橫向加載進度條（漸變色）

progressbar使用

<FrameLayout
            android:id="@+id/fl_video"
            android:layout_width="match_parent"
            android:layout_height="match_parent">
            <wendu.dsbridge.DWebView
                android:id="@+id/webView"
                android:layout_width="match_parent"
                android:layout_height="match_parent"></wendu.dsbridge.DWebView>
            <ProgressBar
                android:id="@+id/progress"
                style="@style/Widget.AppCompat.ProgressBar.Horizontal"
                android:layout_width="match_parent"
                android:layout_height="5dp"
                android:progress="0"
                android:progressDrawable="@drawable/progressbar"
                android:indeterminateTintMode="src_atop"
                android:indeterminateTint="@android:color/holo_blue_light"
                android:max="100">

            </ProgressBar>

        </FrameLayout>

webview中在WebChromeClient監聽進度條

private class MyWebChromeClient extends WebChromeClient {
     
        @Override
        public void onProgressChanged(WebView view, int newProgress) {
            int currentProgress = view.getProgress();
            Log.e(TAG, "onProgressChanged: " + newProgress +"/"+ currentProgress);

            super.onProgressChanged(view, newProgress);

            if (newProgress == 100){
                progress.setVisibility(View.GONE);
                if (smartrefresh != null) {
                    smartrefresh.finishRefresh();
                }
            }else {
                progress.setVisibility(View.VISIBLE);
                progress.setProgress(newProgress);
            }
        }
    }
