我正在开发一个应用程序,我在webview中从外部URL加载网页.加载页面需要花费很多时间才能加载,需要30秒到1分钟,所以请查看我的代码

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.support.v7.widget.Toolbar;
import android.util.Log;
import android.view.MenuItem;
import android.view.View;
import android.webkit.WebView;
import android.webkit.WebViewClient;
import android.widget.ProgressBar;

public class WebActivity extends AppCompatActivity {

    private WebView webView;
    private ProgressBar progressBar;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_web);
        Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar);
        setSupportActionBar(toolbar);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        webView = (WebView)findViewById(R.id.webView);
        progressBar= (ProgressBar)findViewById(R.id.progressBar2);

        String title = getIntent().getExtras().getString("webTitle");
        setTitle(title);
        webView.setVisibility(View.GONE);
        progressBar.setVisibility(View.VISIBLE);
        Log.d("WEB", link);
        webView.setWebViewClient(new MyBrowser());
        webView.getSettings().setJavaScriptEnabled(true);
        //webView.getSettings().setJavaScriptCanOpenWindowsAutomatically(true);
        webView.getSettings().setLoadWithOverviewMode(true);
        webView.getSettings().setUseWideViewPort(true);
        webView.setScrollBarStyle(View.SCROLLBARS_INSIDE_OVERLAY);

        //webView.getSettings().setDomStorageEnabled(true);
        //webView.getSettings().setAppCachePath(String.valueOf(getCacheDir()));
        //webView.getSettings().setAppCacheEnabled(true);
        webView.getSettings().setSupportZoom(true);
        webView.getSettings().setBuiltInZoomControls(true);
        webView.loadUrl(link);
    }
