Android WebView的加载超时处理
WebView中支持超时处理，然后就开始翻api，非常奇怪的是Google竟然没有超时的这项设置。随后又Google到处查阅有没有现成的例子，结果还是一无所获。好吧，还是自己动手写个吧，先直接上代码。
package com.iaiai.activity;import java.util.Timer;import java.util.TimerTask;import android.app.Activity;import android.graphics.Bitmap;import android.os.Bundle;import android.os.Handler;import android.os.Message;import android.util.Log;import android.view.Window;import android.webkit.WebSettings;import android.webkit.WebView;import android.webkit.WebViewClient;public class IaiaiActivity extends Activity { private long timeout = 5000; private WebView mWebView; private Handler mHandler = new Handler(); private Timer timer; @Override public void onCreate(Bundle icicle) { super.onCreate(icicle); requestWindowFeature(Window.FEATURE_NO_TITLE); setContentView(R.layout.main); mWebView = (WebView) findViewById(R.id.webview); WebSettings webSettings = mWebView.getSettings(); webSettings.setJavaScriptEnabled(true); webSettings.setAllowFileAccess(true); mWebView.setWebViewClient(new WebViewClient() { /* * 创建一个WebViewClient,重写onPageStarted和onPageFinished * * * onPageStarted中启动一个计时器,到达设置时间后利用handle发送消息给activity执行超时后的动作. * */ @Override public void onPageStarted(WebView view, String url, Bitmap favicon) { Log.d("testTimeout", "onPageStarted..........."); // TODO Auto-generated method stub super.onPageStarted(view, url, favicon); timer = new Timer(); TimerTask tt = new TimerTask() { @Override public void run() { /* * 超时后,首先判断页面加载进度,超时并且进度小于100,就执行超时后的动作 */ if (TestJsActivity.this.mWebView.getProgress() < 100) { Message msg = new Message(); msg.what = 1; mHandler.sendMessage(msg); timer.cancel(); timer.purge(); } } }; timer.schedule(tt, timeout, 1); } /** * onPageFinished指页面加载完成,完成后取消计时器 */ @Override public void onPageFinished(WebView view, String url) { // TODO Auto-generated method stub super.onPageFinished(view, url); timer.cancel(); timer.purge(); } }); mWebView.loadUrl("http://iaiai.iteye.com"); }}
