我在我的android webview中使用JQuery,而且应用程序非常慢,需要大约10-15秒才能浏览。有没有办法可以加快速度?我已经尝试了书中的每一个帖子和几乎每一个技巧,有什么我想念的吗?是的,我已经在清单中添加了hardwareaccelerated,但仍然没有运气!
public void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
requestWindowFeature(Window.FEATURE_NO_TITLE);
// getWindow().requestFeature(Window.FEATURE_PROGRESS);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN, WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.main);
progress = (ProgressBar) findViewById(R.id.ProgressBar);
progress.setVisibility(View.VISIBLE);
webview = (WebView)findViewById(R.id.webview);
webview.setInitialScale(1);
WebSettings webSettings = webview.getSettings();
webSettings.setJavaScriptEnabled(true);
webview.getSettings().setJavaScriptEnabled(true);
webview.getSettings().setLoadWithOverviewMode(true);
webview.getSettings().setUseWideViewPort(true);
// webview.setWebViewClient(new MyCustomWebViewClient());
if (Build.VERSION.SDK_INT >= 11){
webview.setLayerType(View.LAYER_TYPE_SOFTWARE, null);
}
webview.setScrollBarStyle(View.SCROLLBARS_OUTSIDE_OVERLAY);
webview.setScrollbarFadingEnabled(false);
webview.getSettings().setRenderPriority(RenderPriority.HIGH);
webview.getSettings().setCacheMode(WebSettings.LOAD_NO_CACHE);
// webview.getSettings().setBlockNetworkLoads(true);
webview.getSettings().setBuiltInZoomControls(true);
webview.loadUrl("file:///android_asset/index.html");
webview.getSettings().setDomStorageEnabled(true);
webview.getSettings().setDatabaseEnabled(true);
webview.getSettings().setAppCacheEnabled(true);

webview.getSettings().setSupportZoom(false);
/* webview.setWebChromeClient(new WebChromeClient()
{
public void onProgressChanged(WebView view, int progress)
{
// update the progressBar
MainActivity.this.setProgress(progress * 100);
}
});*/
if (!isTaskRoot()) {
final Intent intent = getIntent();
final String intentAction = intent.getAction();
if (intent.hasCategory(Intent.CATEGORY_LAUNCHER) && intentAction != null && intentAction.equals(Intent.ACTION_MAIN)) {
finish();
return;
}
}
}
private class MyCustomWebViewClient extends WebViewClient {
@Override
public boolean shouldOverrideUrlLoading(WebView view, String url) {
view.loadUrl(url);
return true;
}
public void onPageStarted(WebView view, String url, Bitmap favicon) {
progress.setVisibility(View.VISIBLE);
}
public void onPageFinished(WebView view, String url) {
progress.setVisibility(View.GONE);
synchronized (SPLASH_LOCK) {
SPLASH_LOCK.notifyAll();
}
}
}
}
答案 0 :(得分:1)
请您分享一下究竟有什么慢的详细信息?您要加载的内容是什么?
如果您的代码中存在错误,则会从loadUrl
调用shouldOverrideUrlLoading
。请不要这样做,只需返回true
。
SPLASH_LOCK
用于什么?你在哪里等呢?
