关于android:AndroidAndroid中Intent的用法总结

Intent 只在 Android 中特有，我把它比作一种运载工具，就像飞机一样，会把一些人带到某个中央，而且如果需要的话，还能够找到机上有哪些人员（数据），这就须要另外一些设施来反对（如：Bundle），最初通过引擎（Context 的 Activity）来启动。

   以下是从网上摘来的：前人已有整顿，就不便了咱们这些后辈了。

1. 显示网页:
Java 代码
Uri uri = Uri.parse(“http://www.google.com”);
Intent it = new Intent(Intent.ACTION_VIEW,uri);
startActivity(it);

2. 显示地图:
Java 代码
Uri uri = Uri.parse(“geo:38.899533,-77.036476”);
Intent it = new Intent(Intent.Action_VIEW,uri);
startActivity(it);

3. 从 google 搜寻内容
Java 代码
Intent intent = new Intent();
intent.setAction(Intent.ACTION_WEB_SEARCH);
intent.putExtra(SearchManager.QUERY,”searchString”)
startActivity(intent);

4. 门路布局
Java 代码
Uri uri = Uri.parse(“http://maps.google.com/maps?f=dsaddr=startLat startLng&daddr=endLat endLng&hl=en”);
Intent it = new Intent(Intent.ACTION_VIEW,URI);
startActivity(it);

5. 拨打电话
Java 代码
Uri uri = Uri.parse(“tel:xxxxxx”);
Intent it = new Intent(Intent.ACTION_DIAL, uri);
startActivity(it);
[color=blue]// 要应用这个必须在配置文件 中退出 <uses-permission id=”android .permission.CALL_PHONE” />[/color]

6. 调用发短信的程序
Java 代码
Intent it = new Intent(Intent.ACTION_VIEW);
it.putExtra(“sms_body”, “The SMS text”);
it.setType(“vnd.android-dir/mms-sms”);
startActivity(it);

7. 发送短信
Java 代码
Uri uri = Uri.parse(“smsto:0800000123”);

startActivity(it);

8. 发送彩信

it.putExtra(Intent.EXTRA_STREAM, uri);
it.setType(“image/png”);
startActivity(it);

9. 发送 Email
Java 代码
Uri uri = Uri.parse(“mailto:xxx@abc.com”);
Intent it = new Intent(Intent.ACTION_SENDTO, uri);
startActivity(it);

Intent it = new Intent(Intent.ACTION_SEND);
it.putExtra(Intent.EXTRA_EMAIL, “me@abc.com”);
it.putExtra(Intent.EXTRA_TEXT, “The email body text”);
it.setType(“text/plain”);
startActivity(Intent.createChooser(it, “Choose Email Client”));

Intent it=new Intent(Intent.ACTION_SEND);
String[] tos={“me@abc.com”};
String[] ccs={“you@abc.com”};
it.putExtra(Intent.EXTRA_EMAIL, tos);
it.putExtra(Intent.EXTRA_CC, ccs);
it.putExtra(Intent.EXTRA_TEXT, “The email body text”);
it.putExtra(Intent.EXTRA_SUBJECT, “The email subject text”);
it.setType(“message/rfc822”);
startActivity(Intent.createChooser(it, “Choose Email Client”));

Intent it = new Intent(Intent.ACTION_SEND);
it.putExtra(Intent.EXTRA_SUBJECT, “The email subject text”);
it.putExtra(Intent.EXTRA_STREAM, “file:///sdcard/mysong.mp3”);
sendIntent.setType(“audio/mp3”);
startActivity(Intent.createChooser(it, “Choose Email Client”));
