Android WebKit實(shí)例簡(jiǎn)單實(shí)現(xiàn)是本文要介紹的內(nèi)容，主要是來了解并學(xué)習(xí)Android WebKit實(shí)例的應(yīng)用，具體內(nèi)容的實(shí)現(xiàn)來看詳細(xì)代碼。
Android WebKit實(shí)例簡(jiǎn)單實(shí)現(xiàn)是本文要介紹的內(nèi)容，主要是來了解并學(xué)習(xí)Android WebKit實(shí)例的應(yīng)用，具體內(nèi)容的實(shí)現(xiàn)來看詳細(xì)代碼。
根據(jù)Google上說。你可以在你的應(yīng)用程序中調(diào)用Webkit工具，可以瀏覽一個(gè)www的頁(yè)面，這一點(diǎn)都不假，下面來看看，原理我就不說了。大家可以看看API.
我給個(gè)簡(jiǎn)單的上網(wǎng)例子給大家體驗(yàn)下吧。我試驗(yàn)過，可以成功的。
- package com.gggeye.android;
- import android.app.Activity;
- import android.os.Bundle;
- import android.os.Handler;
- import android.os.Message;
- import android.webkit.DownloadListener;
- import android.webkit.WebView;
- public class WebViewDemo extends Activity {
- /** Called when the activity is first created. */
- @Override
- public void onCreate(Bundle icicle) {
- super.onCreate(icicle);
- setContentView(R.layout.main);
- webView1 = new WebView(this);
- webView1
- .loadData(
- "<html><body>Can I focus?<br /><a href=\"#\">No I cannot!</a>.</body></html>",
- "text/html", "utf-8");
- this.setContentView(webView1);
- Logger.info("Download Faild _=> " + webView1.canGoBack());
- webView = new WebView(this);
- webView.loadUrl("http://www.3geye.net");
- //webView.setDownloadListener(new WebDownloadListener());
- new Thread(new WebDownloadListener(this)).start();
- }
- WebView webView1;
- class WebDownloadListener implements Runnable, DownloadListener {
- WebViewDemo wd;
- WebDownloadListener(WebViewDemo wd){
- this.wd = wd;
- }
- public void run() {
- int j=0;
- StringBuffer sb = new StringBuffer();
- sb.append("正在連接網(wǎng)絡(luò)");
- while (true) {
- try {
- Thread.sleep(4 * 1000);
- j++;
- sb.append(".");
- webView1 = new WebView(wd);
- webView1.loadData("<html><body><font color=\"red\">"
- + sb.toString() + " </font></html>", "text/html",
- "utf-8");
- Message msg = mHandler.obtainMessage();
- mHandler.sendMessage(msg);
- } catch (Throwable e) {
- Logger.info(e.toString());
- e.printStackTrace();
- }
- if (j== 3) {
- webView1 = null;
- Message msg = mHandler.obtainMessage();
- mHandler.sendMessage(msg);
- break;
- }
- }
- }
- public void onDownloadFailed(String arg0, int arg1) {
- Logger.info("Download Faild _=> " + arg0);
- }
- public void onDownloadFinished(String arg0) {
- Logger.info("Download Finished => " + arg0);
- setContentView(webView);
- }
- public void onDownloadStart(String arg0, String arg1, long arg2,
- Message arg3, Message arg4) {
- Logger.info("Download Faild _=> " + arg0);
- }
- public void onDownloadSuspended(String arg0, Message arg1) {
- Logger.info("Download Faild _=> " + arg0);
- }
- }
- Handler mHandler = new Handler(){
- @Override
- public void handleMessage(Message msg) {
- super.handleMessage(msg);
- //invalidate();
- if(webView1 == null)
- setContentView(webView);
- else
- setContentView(webView1);
- }
- };
- WebView webView = null;
- }
小結(jié)：簡(jiǎn)單實(shí)現(xiàn)Android WebKit實(shí)例的內(nèi)容介紹完了，希望通過Android WebKit實(shí)例內(nèi)容的學(xué)習(xí)能對(duì)你有所幫助！
