今天需要写一个跳转到系统拨号页面的功能，其实简单的很，就一句话的事儿。不过念在系统页面众多，于是乎，在此做一个总结，万一以后忘记了，也方便查阅。
系统页面
跳转浏览器浏览网页
Uri uri = Uri.parse("http://www.google.com");
Intent intent = new Intent(Intent.ACTION_VIEW,uri);
startActivity(intent);
拨打电话
//第一种方法
Uri uri = Uri.parse("tel:xxxxxx");
Intent it = new Intent(Intent.ACTION_DIAL, uri);
startActivity(it);
//第二种方法
Uri uri = Uri.parse("tel:"+number);
Intent intent = new Intent(Intent.ACTION_CALL,uri);
startActivity(intent);
调用发短信的程序
Intent it = new Intent(Intent.ACTION_VIEW);
it.putExtra("sms_body", "The SMS text");
it.setType("vnd.android-dir/mms-sms");
startActivity(it);
和
uri = Uri.parse("smsto:"+要发送短信的对方的number);
intent = new Intent(Intent.ACTION_SENDTO,uri);
startActivity(intent);
和
mIntent = new Intent(Intent.ACTION_VIEW);
mIntent.putExtra("address", c.getString(c.getColumnIndex(column)));
mIntent.setType("vnd.android-dir/mms-sms");
startActivity(mIntent);
发送短信
Uri uri = Uri.parse("smsto:0800000123");
Intent it = new Intent(Intent.ACTION_SENDTO, uri);
it.putExtra("sms_body", "The SMS text");
startActivity(it);
String body="this is sms demo";
Intent mmsintent = new Intent(Intent.ACTION_SENDTO, Uri.fromParts("smsto", number, null));
mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_MESSAGE_BODY, body);
mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_COMPOSE_MODE, true);
mmsintent.putExtra(Messaging.KEY_ACTION_SENDTO_EXIT_ON_SENT, true);
startActivity(mmsintent);
播放多媒体
Intent it = new Intent(Intent.ACTION_VIEW);
Uri uri = Uri.parse("file:///sdcard/song.mp3");
it.setDataAndType(uri, "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);
uninstall apk
Uri uri = Uri.fromParts("package", strPackageName, null);
Intent it = new Intent(Intent.ACTION_DELETE, uri);
startActivity(it);
install apk
Uri installUri = Uri.fromParts("package", "xxx", null);
returnIt = new Intent(Intent.ACTION_PACKAGE_ADDED, installUri);
打开照相机
<1>Intent i = new Intent(Intent.ACTION_CAMERA_BUTTON, null);
this.sendBroadcast(i);
<2>long dateTaken = System.currentTimeMillis();
String name = createName(dateTaken) + ".jpg";
fileName = folder + name;
ContentValues values = new ContentValues();
values.put(Images.Media.TITLE, fileName);
values.put("_data", fileName);
values.put(Images.Media.PICASA_ID, fileName);
values.put(Images.Media.DISPLAY_NAME, fileName);
values.put(Images.Media.DESCRIPTION, fileName);
values.put(Images.ImageColumns.BUCKET_DISPLAY_NAME, fileName);
Uri photoUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
Intent inttPhoto = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
inttPhoto.putExtra(MediaStore.EXTRA_OUTPUT, photoUri);
startActivityForResult(inttPhoto, 10);
从gallery选取图片
Intent i = new Intent();
i.setType("image/*");
i.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(i, 11);
- 打开录音机
Intent mi = new Intent(Media.RECORD_SOUND_ACTION);
startActivity(mi);
16.显示应用详细列表
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
刚才找app id未果，结果发现用package name也可以 Uri uri = Uri.parse("market://details?id=<packagename>");
这个简单多了
寻找应用
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
打开联系人列表
Intent i = new Intent();
i.setAction(Intent.ACTION_GET_CONTENT);
i.setType("vnd.android.cursor.item/phone");
startActivityForResult(i, REQUEST_TEXT);
Uri uri = Uri.parse("content://contacts/people");
Intent it = new Intent(Intent.ACTION_PICK, uri);
startActivityForResult(it, REQUEST_TEXT);
打开另一程序
Intent i = new Intent();
ComponentName cn = new ComponentName("com.yellowbook.android2", "com.yellowbook.android2.AndroidSearch");
i.setComponent(cn);
i.setAction("android.intent.action.MAIN");
startActivityForResult(i, RESULT_OK);
添加到短信收件箱
ContentValues cv = new ContentValues();
cv.put("type", "1");
cv.put("address","短信地址");
cv.put("body", "短信内容");
getContentResolver().insert(Uri.parse("content://sms/inbox"), cv);
从sim卡或者联系人中查询
Cursor cursor;
Uri uri;
if (type == 1) {
Intent intent = new Intent();
intent.setData(Uri.parse("content://icc/adn"));
uri = intent.getData();
} else
uri = People.CONTENT_URI;
cursor = activity.getContentResolver().query(uri, null, null, null, null);
while (cursor.moveToNext()) {
int peopleId = cursor.getColumnIndex(People._ID);
int nameId = cursor.getColumnIndex(People.NAME);
int phoneId = cursor.getColumnIndex(People.NUMBER);}
查看某个联系人，当然这里是ACTION_VIEW，如果为选择并返回action改为ACTION_PICK，当然处理intent时返回需要用到 startActivityforResult
Uri personUri = ContentUris.withAppendedId(People.CONTENT_URI, ID);//最后的ID参数为联系人Provider中的数据库BaseID，即哪一行
Intent intent = new Intent(); intent.setAction(Intent.ACTION_VIEW); intent.setData(personUri); startActivity(intent);
删除
uri = ContentUris.withAppendedId(People.CONTENT_URI, 联系人id);
int count = activity.getContentResolver().delete(uri, null, null
添加到联系人：
ContentValues cv = new ContentValues();
ArrayList<ContentProviderOperation> operationList = new ArrayList<ContentProviderOperation>();
ContentProviderOperation.Builder builder = ContentProviderOperation.newInsert(RawContacts.CONTENT_URI);
builder.withValues(cv);
operationList.add(builder.build());
builder = ContentProviderOperation.newInsert(Data.CONTENT_URI);
builder.withValueBackReference(StructuredName.RAW_CONTACT_ID, 0);
builder.withValue(Data.MIMETYPE, StructuredName.CONTENT_ITEM_TYPE);
builder.withValue(StructuredName.DISPLAY_NAME, "自定义联系人名");
operationList.add(builder.build());
builder = ContentProviderOperation.newInsert(Data.CONTENT_URI);
builder.withValueBackReference(Phone.RAW_CONTACT_ID, 0);
builder.withValue(Data.MIMETYPE, Phone.CONTENT_ITEM_TYPE);
builder.withValue(Phone.NUMBER, "联系人的phonenumber");
builder.withValue(Data.IS_PRIMARY, 1);
operationList.add(builder.build());
try {
getContentResolver().applyBatch(ContactsContract.AUTHORITY, operationList);
} catch (RemoteException e) {
e.printStackTrace();
} catch (OperationApplicationException e) {
e.printStackTrace();
}
选择一个图片
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
intent.addCategory(Intent.CATEGORY_OPENABLE);
intent.setType("image/*");
startActivityForResult(intent, 0);
调用Android设备的照相机，并设置拍照后存放位置
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment .getExternalStorageDirectory().getAbsolutePath()+"/cwj", android123 + ".jpg"))); //存放位置为sdcard卡上cwj文件夹，文件名为android123.jpg格式
startActivityForResult(intent, 0);
在market上搜索指定package name，
比如搜索com.android123.cwj的写法如下
Uri uri = Uri.parse("market://search?q=pname:com.android123.cwj");
Intent intent = new Intent(Intent.ACTION_VIEW, uri); startActivity(intent);
获取文件信息，并使用相对应软件打开
private void openFile(File f)
{
Intent intent = new Intent();
intent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
intent.setAction(android.content.Intent.ACTION_VIEW);
String type = getMIMEType(f);
intent.setDataAndType(Uri.fromFile(f), type);
startActivity(intent);
}
private String getMIMEType(File f){
String end = f .getName() .substring(f.getName().lastIndexOf(".") + 1,f.getName().length()).toLowerCase();
String type = "";
if (end.equals("mp3") || end.equals("aac") || end.equals("aac")|| end.equals("amr") || end.equals("mpeg")|| end.equals("mp4"))
{
type = "audio";
}
else if (end.equals("jpg") || end.equals("gif")|| end.equals("png") || end.equals("jpeg"))
{
type = "image";
}
else
{
type = "*";
}
type += "/*";
return type;
}
