Question

我使用XWalkView加载网页，如下所示：

private boolean isCacheAvailable(){
    File dir  = getApplicationContext().getCacheDir();
    if (dir.exists())
        return dir.listFiles().length > 0;
    else
        return false;
};

活动

<org.xwalk.core.XWalkView android:id="@+id/webview"
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        >
</org.xwalk.core.XWalkView>

有关实现XWalkView的详细信息，请参阅我的post。

但是现在，由于页面内容太多，它会调用4~5秒进行finshing加载。这将导致应用页面空白。我想为XWalkView添加加载进度。对于XWalkView只有很少的演示，我真的不知道从哪里开始。

任何帮助将不胜感激。 Thansk！

编辑：在我尝试按照@Srihari的回答后，又出现了另一个问题。进展表现良好，当它完成100％时，它就会消失。但它在页面完成加载后很快再次以100％跳出，并且从未消失。

活动：

XWalkView mXWalkView = (XWalkView) findViewById(R.id.webview);
mXWalkView.load("http://xxxxxxxx", null);

xml

class ResourceClient extends XWalkResourceClient {
    public ResourceClient(XWalkView xwalkView) {
        super(xwalkView);
    }

    public void onLoadStarted(XWalkView view, String url) {
        mProgress = (ProgressBar) findViewById(R.id.progressBar);
        mProgress.setVisibility(View.VISIBLE);
        super.onLoadStarted(view, url);
        Log.d("INFO", "Load Started:" + url);
    }

    public void onLoadFinished(XWalkView view, String url) {
        super.onLoadFinished(view, url);
        Log.d("INFO", "Load Finished:" + url);
        bottomBar = (BottomBar) findViewById(R.id.bottomBar);
        mProgress = (ProgressBar) findViewById(R.id.progressBar);
        mProgress.setVisibility(View.GONE);
    }

    public void onProgressChanged(XWalkView view, int progressInPercent) {
        super.onProgressChanged(view, progressInPercent);
        Log.d("INFO", "Loading Progress:" + progressInPercent);
        mProgress = (ProgressBar) findViewById(R.id.progressBar);
        mProgress.setProgress(progressInPercent);
    }

在我修复我的问题之前我去makkah做umrah我尝试2天解决问题后umrah我需要2分钟并解决我的问题我的上帝帮助我

请不要删除我们从上帝那里得到的所有话题

你需要向上帝祷告，你会得到你想要的一切吗

这是我的MainActivity

__kernel void unprimed_grid_int(your_arguments, int test) {

    if (get_global_id(0) == 734207) {
        test = 10; // or any other value
    }
}

我跳这个帮助你

Answer 2

显示该活动或片段的创建进度条。

xWalkView.setResourceClient(new XWalkResourceClient(xWalkView){
    @Override
    public void onLoadFinished(XWalkView view, String url) {
        super.onLoadFinished(view, url);
        // Stop your progress bar here
    }
});

希望这可以帮到你..

我解决了我的问题，这是在activity_main：

<org.xwalk.core.XWalkView xmlns:android="http://schemas.android.com/apk/res/android"
        android:id="@+id/webview"
        android:layout_width="match_parent"
        android:layout_height="match_parent" >

        <FrameLayout
            android:id="@+id/framelayout"
            android:layout_width="match_parent"
            android:layout_height="3dp"
            android:background="@android:color/transparent"
            android:visibility="visible"></FrameLayout>

        <ProgressBar
            android:id="@+id/ProgressBar"
            style="@android:style/Widget.DeviceDefault.Light.ProgressBar.Large"
            android:layout_width="match_parent"
            android:layout_height="4dp"
            android:layout_gravity="top"
            android:layout_marginTop="3dp"
            android:background="@android:color/transparent"
            android:progress="10"
            android:progressDrawable="@drawable/custom_progress" />
    </org.xwalk.core.XWalkView>

我发现在我的问题中，我所讨论的behivour是由我页面中的动态内容引起的。因为我的页面有stlloader，所以我实现了xwalkview加载进度和stlloader加载进度。

Xwalkview加载进度：

class ResourceClient extends XWalkResourceClient {
    public ResourceClient(XWalkView xwalkView) {
        super(xwalkView);
    }

    public void onLoadStarted(XWalkView view, String url) {
        mProgress = (ProgressBar) findViewById(R.id.progressBar);
        mProgress.setVisibility(View.VISIBLE);
        super.onLoadStarted(view, url);
        Log.d("INFO", "Load Started:" + url);
    }

    public void onLoadFinished(XWalkView view, String url) {
        super.onLoadFinished(view, url);
        Log.d("INFO", "Load Finished:" + url);
        bottomBar = (BottomBar) findViewById(R.id.bottomBar);
        mProgress = (ProgressBar) findViewById(R.id.progressBar);
        mProgress.setVisibility(View.GONE);
    }

    public void onProgressChanged(XWalkView view, int progressInPercent) {
        super.onProgressChanged(view, progressInPercent);
        Log.d("INFO", "Loading Progress:" + progressInPercent);
        mProgress = (ProgressBar) findViewById(R.id.progressBar);
        mProgress.setProgress(progressInPercent);
    }

stlloader加载进度：

      var loader = new THREE.STLLoader(manager);
      loader.load( "{{ $modelfilepath }}", function ( geometry ) {
          var meshMaterial = new THREE.MeshPhongMaterial( { color: 0xAAAAAA, specular: 0x111111, shininess: 200 } );
          if (geometry.hasColors) {
              meshMaterial = new THREE.MeshPhongMaterial({ opacity: geometry.alpha, vertexColors: THREE.VertexColors });
          }
          centerOffset = geometry.center();
          var mesh = new THREE.Mesh( geometry, meshMaterial );
          tV.z = (-geometry.boundingBox.min.z + geometry.boundingBox.max.z)/2;
          mesh.matrix.elements[14] = tV.z;
          mesh.castShadow = true;
          mesh.receiveShadow = true;
          mesh.matrixAutoUpdate = false;

          boundBox.setFromObject(mesh);
          if(!isFillin(boundBox.min, boundBox.max, machineLength))
          {
              mesh.material.color.setHex(0xff0000);
          }

          stlMesh = mesh;
          scene.add( mesh );
          objects.push(mesh);
          showPosition(0, 0, tV.z);
      }, function(progressItem) {
          $('#loaderstatus').html("Loading... " + (Math.round(progressItem.loaded / progressItem.total *100)) + "%");
      }, function(){

      });
