手机照相或选择相册，类似新浪微博的图片处理

拍照的

1. btn1.setOnClickListener(new OnClickListener() {  
2.   
3.     @Override  
4.     public void onClick(View v) {  
5.   
6.         Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);  
7.   
8.         File out = new File(Environment.getExternalStorageDirectory(),  
9.                 "camera.png");  
10.         Uri uri = Uri.fromFile(out);  
11.         intent.putExtra(MediaStore.EXTRA_OUTPUT, uri);  
12.         xxActivity.startActivityForResult(intent, 3);  
13.                     }  
14. });

相册

1. btn2.setOnClickListener(new OnClickListener() {  
2.   
3.         @Override  
4.         public void onClick(View v) {  
5.             Intent intent = new Intent(Intent.ACTION_GET_CONTENT);  
6.             intent.addCategory(Intent.CATEGORY_OPENABLE);  
7.             intent.setType("image/*");  
8.             intent.putExtra("crop", "true");  
9.             intent.putExtra("aspectX", 1);  
10.             intent.putExtra("aspectY", 1);  
11.             intent.putExtra("outputX", 80);  
12.             intent.putExtra("outputY", 80);  
13.             intent.putExtra("return-data", true);  
14.   
15.             xxActivity.startActivityForResult(intent, 2);  
16.                         }  
17.     });

处理的activity

Java代码 

1. protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
2.         if (resultCode != RESULT_OK) {  
3.             return;  
4.         } else {  
5.   
6.             switch (requestCode) {  
7.             case 2:  
8.                 Bitmap cameraBitmap = (Bitmap) data.getExtras().get("data");  
9.                 Home.personalinfo.headbmp = cameraBitmap;  
10.                 try {  
11.                     String str = saveMyBitmap(cameraBitmap);  
12.                   
13.   
14.                 } catch (IOException e) {  
15.                     e.printStackTrace();  
16.                 }  
17.   
18.                 break;  
19.   
20.             /* 拍照后保存图片，并跳到裁剪功能 */  
21.             case 3:  
22.   
23.                 new saveAsy().execute("");  
24.                 break;  
25.             }  
26.   
27.         }  
28.         super.onActivityResult(requestCode, resultCode, data);  
29.     }

 saveAsy的方法

Java代码 

1. class saveAsy extends AsyncTask<String, Object, String> {  
2.   
3.   
4.   
5.   
6.   
7.     @Override  
8.     protected String doInBackground(String... str) {  
9.         dispathBitmap();  
10.         Intent intent = new Intent("com.android.camera.action.CROP");  
11.         try {  
12.             intent.setData(Uri  
13.                     .parse(android.provider.MediaStore.Images.Media  
14.                             .insertImage(getContentResolver(),  
15.                                     storageUrl+"/camera.png", null, null)));  
16.         } catch (FileNotFoundException e) {  
17.             e.printStackTrace();  
18.         }  
19.         intent.putExtra("crop", "true");  
20.         intent.putExtra("aspectX", 1);  
21.         intent.putExtra("aspectY", 1);  
22.         intent.putExtra("outputX", 80);  
23.         intent.putExtra("outputY", 80);  
24.         intent.putExtra("return-data", true);  
25.         startActivityForResult(intent, 2);  
26.   
27.         return "";  
28.     }  
29.   
30.     @Override  
31.     protected void onPostExecute(String bmp) {  
32.         super.onPostExecute(bmp);
