Intent用法實(shí)例 1.無參數(shù)Activity跳轉(zhuǎn) Java代碼 Intent it = new Intent(Activity.Main.this, Activity2.class); startActivity(it); 2.向下一個(gè)Activity傳遞數(shù)據(jù)（使用Bundle和Intent.putExtras） Java代碼 Intent it = new Intent(Activity.Main.this, Activity2.class); Bundle bundle=new Bundle(); bundle.putString("name", "This is from MainActivity!"); it.putExtras(bundle); // it.putExtra(“test”, "shuju”); startActivity(it); // startActivityForResult(it,REQUEST_CODE); 對于數(shù)據(jù)的獲取可以采用： Java代碼 Bundle bundle=getIntent().getExtras(); String name=bundle.getString("name"); 3.向上一個(gè)Activity返回結(jié)果（使用setResult，針對startActivityForResult(it,REQUEST_CODE)啟動的Activity） Java代碼 Intent intent=getIntent(); Bundle bundle2=new Bundle(); bundle2.putString("name", "This is from ShowMsg!"); intent.putExtras(bundle2); setResult(RESULT_OK, intent); 4.回調(diào)上一個(gè)Activity的結(jié)果處理函數(shù)（onActivityResult） Java代碼 @Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub super.onActivityResult(requestCode, resultCode, data); if (requestCode==REQUEST_CODE){ if(resultCode==RESULT_CANCELED) setTitle("cancle"); else if (resultCode==RESULT_OK) { String temp=null; Bundle bundle=data.getExtras(); if(bundle!=null) temp=bundle.getString("name"); setTitle(temp); } } } 下面是轉(zhuǎn)載來的其他的一些Intent用法實(shí)例（轉(zhuǎn)自javaeye） 顯示網(wǎng)頁 Java代碼 1.

Uri uri = Uri.parse("tel:0800000123"); 3. Intent it = new Intent(Intent.ACTION_DIAL, uri); 4. startActivity(it); 1. //直接打電話出去 2. Uri uri = Uri.parse("tel:0800000123"); 3.
