Android-學習記錄（二、Intent），android-intent

用到了Intent，先記錄一下最常用的方式

一、顯示網頁

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

二、顯示地圖

  
Uri uri = Uri.parse("geo:38.899533,-77.036476");    
Intent it = new Intent(Intent.Action_VIEW,uri);    
startActivity(it);

三、路徑規劃

  
Uri uri = Uri.parse("http://maps.google.com/maps?f=d&saddr=startLat%20startLng&daddr=endLat%20endLng&hl=en");    
Intent it = new Intent(Intent.ACTION_VIEW,URI);    
startActivity(it);

四、撥打到電話（調用撥號程式）

  
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);

  
要使用這個必須在設定檔中加入<uses-permission id="android.permission.CALL_PHONE" />

五、發送SMS/MMS

  
1、調用傳送簡訊的程式
  
Intent it = new Intent(Intent.ACTION_VIEW);   
it.putExtra("sms_body", "The SMS text");   
it.setType("vnd.android-dir/mms-sms");   
startActivity(it); 
  
 
  
2、傳送簡訊
  
Uri uri = Uri.parse("smsto:0800000123");   
Intent it = new Intent(Intent.ACTION_SENDTO, uri);   
it.putExtra("sms_body", "The SMS text");   
startActivity(it); 
  
 
  
3、發送多媒體訊息
  
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);

六、發送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")); 

七、播放多媒體

  
Intent intent = new Intent(Intent.ACTION_VIEW); 
  
Uri uri = Uri.parse("file:///sdcard/foo.mp3"); 
  
intent.setDataAndType(uri, "audio/mp3"); 
  
startActivity(intent); 
  
Uri uri = Uri.withAppendedPath(MediaStore.Audio.Media.INTERNAL_CONTENT_URI, "1"); 
  
Intent intent = new Intent(Intent.ACTION_VIEW, uri); 
  
startActivity(intent);

八、拍照

  
// 開啟拍照程式
  
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
  
startActivityForResult(intent, 0);
  
// 取出照片資料
  
Bundle extras = intent.getExtras(); 
  
Bitmap bitmap = (Bitmap) extras.get("data"); 

九、擷取並剪下圖片

  
// 擷取並剪下圖片
  
Intent intent = new Intent(Intent.ACTION_GET_CONTENT);
  
intent.setType("image/*");
  
intent.putExtra("crop", "true"); // 開啟剪下
  
intent.putExtra("aspectX", 1); // 剪下的寬高比為1：2
  
intent.putExtra("aspectY", 2);
  
intent.putExtra("outputX", 20); // 儲存圖片的寬和高
  
intent.putExtra("outputY", 40); 
  
intent.putExtra("output", Uri.fromFile(new File("/mnt/sdcard/temp"))); // 儲存路徑
  
intent.putExtra("outputFormat", "JPEG");// 返回格式
  
startActivityForResult(intent, 0);
  
// 剪下特定圖片
  
Intent intent = new Intent("com.android.camera.action.CROP"); 
  
intent.setClassName("com.android.camera", "com.android.camera.CropImage"); 
  
intent.setData(Uri.fromFile(new File("/mnt/sdcard/temp"))); 
  
intent.putExtra("outputX", 1); // 剪下的寬高比為1：2
  
intent.putExtra("outputY", 2);
  
intent.putExtra("aspectX", 20); // 儲存圖片的寬和高
  
intent.putExtra("aspectY", 40);
  
intent.putExtra("scale", true);
  
intent.putExtra("noFaceDetection", true); 
  
intent.putExtra("output", Uri.parse("file:///mnt/sdcard/temp")); 
  
startActivityForResult(intent, 0); 

十、進入設定介面

  
// 進入無線網路設定介面（其它可以舉一反三）  
  
Intent intent = new Intent(android.provider.Settings.ACTION_WIRELESS_SETTINGS);  
  
startActivityForResult(intent, 0); 
  
 

先弄這點吧，找著挺費勁的，這點應該能應付一定的功能了。累死了~~~~不想工作~~~~~
