显示意图要求必须知道被激活组件的包和class
隐式意图只需要知道跳转activity的动作和数据,就可以激活对应的组件
A 主activity B 接收跳转的activity
步骤
1:在主配置文件中声明B 至少要声明一个android:name属性
[html]
<activity
android:name=".DemoActivity"
android:label="@string/demoActivity" >
<intent-filter>
<!-- 隐士意图中指定intent的名字 自己定义 可匹配多项 -->
<action android:name="com.itcast.intent.DemoActivity" />
<!-- 隐式intent需要指定的activity的类型,可自己定义该值,需要在调用的时候相对应不写该项默认为 android.intent.category.DEFAULT,可匹配多项 -->
<category android:name="android.intent.category.DEFAULT" />
<!-- 指定传想该activity数值的类型 和主机,如果指定该项,就必须在跳转activity的时候传入还数据和主机名 -->
<data
android:host="cn.itcast.demo"
android:scheme="itcast" />
</intent-filter>
</activity>

//将电话号码传入拨号程序
Intent intent = new Intent(Intent.ACTION_DIAL, Uri .parse("tel:123456789"));
startActivity(intent);
|
//直接的拨打相应号码
Intent intent = new Intent(Intent.ACTION_CALL, Uri .parse("tel:123456789"));
startActivity(intent);

路径规划: 1. Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en"); 2. Intent it = new Intent(Intent.ACTION_VIEW,URI); 3. startActivity(it); |
//查看指定联系人
Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, info.id);//info.id联系人ID Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setData(personUri); startActivity(intent); |
拨打电话: 调用拨号程序 1. Uri uri = Uri.parse("tel:xxxxxx"); 2. Intent it = new Intent(Intent.ACTION_DIAL, uri); 3. startActivity(it); 1. Uri uri = Uri.parse("tel.xxxxxx"); 2. Intent it =new Intent(Intent.ACTION_CALL,uri); 3. 要使用这个必须在配置文件中加入<uses-permission id="Android.permission.CALL_PHONE" /> |
Uninstall 程序 1. Uri uri = Uri.fromParts("package", strPackageName, null); 2. Intent it = new Intent(Intent.ACTION_DELETE, uri); 3. startActivity(it); |
|
//进入联系人页面
Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setData(People.CONTENT_URI); startActivity(intent); |
//搜索应用
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 |
发送SMS/MMS
调用发送短信的程序 1. Intent it = new Intent(Intent.ACTION_VIEW); 2. it.putExtra("sms_body", "The SMS text"); 3. it.setType("vnd.android-dir/mms-sms"); 4. startActivity(it); |
//调用相册
public static final String MIME_TYPE_IMAGE_JPEG = "image/*"; public static final int ACTIVITY_GET_IMAGE = 0; Intent getImage = new Intent(Intent.ACTION_GET_CONTENT); getImage.addCategory(Intent.CATEGORY_OPENABLE); getImage.setType(MIME_TYPE_IMAGE_JPEG); startActivityForResult(getImage, ACTIVITY_GET_IMAGE); |
|
//发送附件
Intent it = new Intent(Intent.ACTION_SEND); it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text"); it.putExtra(Intent.EXTRA_STREAM, "[url=]file:///sdcard/eoe.mp3[/url]"); sendIntent.setType("audio/mp3"); startActivity(Intent.createChooser(it, "Choose Email Client")); |
install apk
Uri installUri = Uri.fromParts("package", "xxx", null); returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri); play audio Uri playUri = Uri.parse("[url=]file:///sdcard/download/everything.mp3[/url]"); returnIt = new Intent(Intent.ACTION_VIEW, playUri); |
播放多媒体
1. 2. Intent it = new Intent(Intent.ACTION_VIEW); 3. Uri uri = Uri.parse("[url=]file:///sdcard/song.mp3[/url]"); 4. it.setDataAndType(uri, "audio/mp3"); 5. startActivity(it); 1. Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1"); 2. Intent it = new Intent(Intent.ACTION_VIEW, uri); 3. startActivity(it); |
//调用系统相机应用程序，并存储拍下来的照片
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); time = Calendar.getInstance().getTimeInMillis(); intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment .getExternalStorageDirectory().getAbsolutePath()+"/tucue", time + ".jpg"))); startActivityForResult(intent, ACTIVITY_GET_CAMERA_IMAGE); |
|
添加附件
1. Intent it = new Intent(Intent.ACTION_SEND); 2. it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text"); 3. it.putExtra(Intent.EXTRA_STREAM, "[url=]file:///sdcard/mysong.mp3[/url]"); 4. sendIntent.setType("audio/mp3"); 5. startActivity(Intent.createChooser(it, "Choose Email Client")); |
发送短信 1. Uri uri = Uri.parse("smsto:0800000123"); 2. Intent it = new Intent(Intent.ACTION_SENDTO, uri); 3. it.putExtra("sms_body", "The SMS text"); 4. startActivity(it); |
发送彩信 1. Uri uri = Uri.parse("content://media/external/images/media/23"); 2. Intent it = new Intent(Intent.ACTION_SEND); 3. it.putExtra("sms_body", "some text"); 4. it.putExtra(Intent.EXTRA_STREAM, uri); 5. it.setType("image/png"); 6. startActivity(it); |
发送Email
1. 2. Uri uri = Uri.parse("mailto:xxx@abc.com"); 3. Intent it = new Intent(Intent.ACTION_SENDTO, uri); 4. startActivity(it); 1. Intent it = new Intent(Intent.ACTION_SEND); 2. it.putExtra(Intent.EXTRA_EMAIL, "me@abc.com"); 3. it.putExtra(Intent.EXTRA_TEXT, "The email body text"); 4. it.setType("text/plain"); 5. startActivity(Intent.createChooser(it, "Choose Email Client")); 1. Intent it=new Intent(Intent.ACTION_SEND); 2. String[] tos={"me@abc.com"}; 3. String[] ccs={"you@abc.com"}; 4. it.putExtra(Intent.EXTRA_EMAIL, tos); 5. it.putExtra(Intent.EXTRA_CC, ccs); 6. it.putExtra(Intent.EXTRA_TEXT, "The email body text"); 7. it.putExtra(Intent.EXTRA_SUBJECT, "The email subject text"); 8. it.setType("message/rfc822"); 9. startActivity(Intent.createChooser(it, "Choose Email Client")); |

显示网页:
1. Uri uri = Uri.parse("http://www.google.com"); |
显示地图:
1. Uri uri = Uri.parse("geo:38.899533,-77.036476"); 2. Intent it = new Intent(Intent.Action_VIEW,uri); 3. startActivity(it); |
uninstall apk
/**未测试 Uri uninstallUri = Uri.fromParts("package", "xxx", null); returnIt = new Intent(Intent.ACTION_DELETE, uninstallUri); */ Uri packageURI = Uri.parse("package:"+wistatmap); Intent uninstallIntent = new Intent(Intent.ACTION_DELETE, packageURI); startActivity(uninstallIntent); |
