Intent的一些用法（不断更新）

Intent用法实例

1.无参数Activity跳转

Java代码

Intent it = new Intent(Activity.Main.this, Activity2.class);

startActivity(it);



2.向下一个Activity传递数据（使用Bundle和Intent.putExtras）

Java代码

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);

对于数据的获取可以采用：

Java代码

Bundle bundle=getIntent().getExtras();

String name=bundle.getString("name");

3.向上一个Activity返回结果（使用setResult，针对startActivityForResult(it,REQUEST_CODE)启动的Activity）

Java代码

Intent intent=getIntent();

Bundle bundle2=new Bundle();

bundle2.putString("name", "This is from ShowMsg!");

intent.putExtras(bundle2);

setResult(RESULT_OK, intent);



4.回调上一个Activity的结果处理函数（onActivityResult）

Java代码

@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);

}

}

}

下面是转载来的其他的一些Intent用法实例（转自javaeye）

it.putExtra(Intent.EXTRA_STREAM, "file:///sdcard/mysong.mp3");

sendIntent.setType("audio/mp3");

startActivity(Intent.createChooser(it, "Choose Email Client"));



播放多媒体

Java代码

Uri uri = Uri.parse("file:///sdcard/song.mp3");

Intent it = new Intent(Intent.ACTION_VIEW, uri);

it.setType("audio/mp3");

startActivity(it);

Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1");

Intent it = new Intent(Intent.ACTION_VIEW, uri);

startActivity(it);



Market 相关
//寻找某个应用

Java代码

Uri uri = Uri.parse("market://search?q=pname:pkg_name");

Intent it = new Intent(Intent.ACTION_VIEW, uri);

startActivity(it);



//where pkg_name is the full package path for an application

Java代码

显示某个应用的相关信息

Uri uri = Uri.parse("market://details?id=app_id");

Intent it = new Intent(Intent.ACTION_VIEW, uri);

startActivity(it);

//where app_id is the application ID, find the ID

//by clicking on your application on Market home

//page, and notice the ID from the address bar



Uninstall 应用程序

Java代码

Uri uri = Uri.fromParts("package", strPackageName, null);

Intent it = new Intent(Intent.ACTION_DELETE, uri);

startActivity(it);



返回桌面

Java代码

Intent unMyIntent = new Intent(Intent.ACTION_MAIN);

unMyIntent.addCategory(Intent.CATEGORY_HOME);

startActivity(unMyIntent);

发邮件

Java代码

Uri uri = Uri.parse("mailto:fengsheng.studio@hotmail.com");

Intent it = new Intent(Intent.ACTION_SENDTO, uri);

发送文件

Java代码

Intent intent = new Intent();

intent.setAction(Intent.ACTION_SEND);

intent.setType(mimeType);

intent.putExtra(Intent.EXTRA_STREAM, uri);

startActivity(intent);



以上有两个变量需要说明:

1. mimeType: 如果是图片,则为"image/*",如果是音频,则为"audio/*",如果是视频,则为"video/*"

2. uri:如果是直接读取到文件路径并发送,则为Uri.fromFile(new File(filePath));

如果是从数据库中查循出来的uri,则直接传入即可.



Intent 模糊匹配：



1、指定activity匹配的Uri类型

<activity android:anme="HelloWord"

android:label="@string/app_name">

<intent-filter>

<action android:name="android.intent.action.VIEW" />

<category android:name="android.intent.category.DEFAULT" />

<category android:name="android.intent.category.BROWSABLE" />

<data android:scheme="http" android:host="www.google.com " />

</intent-filter>

</activity>



Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.google.com"));

startActivity(intent);
