Android调用默认浏览器打开指定Url的方法实例

http://www.jb51.net/article/41306.htm

业务员有需求要将一个wap站在手机上以App的形式打开,还不要嵌套WebView,只能以浏览器打开.查了点资料,就有了下面这代码

点击(此处)折叠或打开

  1. package com.gzz.whyinzi;

  3. import android.net.Uri;
  4. import android.os.Bundle;
  5. import android.app.Activity;
  6. import android.content.Intent;
  7. import android.util.Log;
  8. import android.view.Menu;
  9. import android.view.View;

  11. public class MainActivity extends Activity {
  12.     private static final String TAG = "ActivityDemo";

  14.     @Override
  15.     protected void onCreate(Bundle savedInstanceState) {
  16.         super.onCreate(savedInstanceState);
  17.         setContentView(R.layout.activity_main);

  19.        
  20.         Intent intent = new Intent();
  21.         intent.setAction("android.intent.action.VIEW");
  22.         Uri content_url = Uri.parse(http://www.jb51.net);
  23.         intent.setData(content_url);
  24.         startActivity(intent);

  26.        
  27.     }

  29.         @Override
  30.         protected void onResume() {
  31.             super.onResume();
  32.             Intent intent = new Intent();
  33.             intent.setAction("android.intent.action.VIEW");
  34.             Uri content_url = Uri.parse("http://play.jb51.net");
  35.             intent.setData(content_url);
  36.             startActivity(intent);
  37.             Log.e(TAG, "start onResume~~~");
  38.         }

  40.         @Override
  41.         protected void onStop() {
  42.             super.onStop();
  43.             this.finish();
  44.             Log.e(TAG, "start onStop~~~");
  45.         }
  46. }

onResume()在没有默认浏览器的时候就起作用了,当没有默认浏览器的时候会弹出提示以哪个浏览器打开,如果点击取消就会出现黑色背景,为防止出现黑色背景,onsume()重新调用打开浏览器.

onStop()在选择浏览器后结束进程.
