调用android系统自带功能

我们如何才能调用android系统自带的功能呢。其实我们调用的功能都是很常见的，其中有播放器、短信、电话。网页等。下面我们就来说说调用android系统功能的主要代码。

//显示网页: 
Uri uri = Uri.parse("http://www.google.com");

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

startActivity(it);



//显示地图: 
Uri uri = Uri.parse("geo:38.899533,-77.036476");

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

startActivity(it);

//路径规划: 
Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat20startLng&daddr=endLat%20endLng&hl=en");

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

startActivity(it);





//调用拨号程序 
Uri uri = Uri.parse("tel:xxxxxx");

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

startActivity(it);


Uri uri = Uri.parse("tel.xxxxxx");

Intent it =new Intent(Intent.ACTION_CALL,uri);//要使用这个必须在配置文件中加入




发送SMS/MMS

//发送短信的程序 
Intent it = new Intent(Intent.ACTION_VIEW);

it.putExtra("sms_body", "The SMS text");

it.setType("vnd.android-dir/mms-sms");

startActivity(it);

//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);

　　

//发送彩信 
Uri uri = Uri.parse("content://media/external/images/media/23");

Intent it = new Intent(Intent.ACTION_SEND);

it.putExtra("sms_body", "some text");

it.putExtra(Intent.EXTRA_STREAM, uri);

it.setType("image/png");

startActivity(it);

　


//发送Email
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"));




//添加附件 
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"));




//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);
