android获取本地图片或拍照图片

先贴代码

获取图片：

注释：拍照获取的话，可以指定图片的保存地址，在此不说明。

  CharSequence[] items = {"相册", "相机"};         new AlertDialog.Builder(this)        .setTitle("选择图片来源")        .setItems(items, new OnClickListener() {      public void onClick(DialogInterface dialog, int which) {       if( which == SELECT_PICTURE ){        Intent intent = new Intent(Intent.ACTION_GET_CONTENT);        intent.addCategory(Intent.CATEGORY_OPENABLE);        intent.setType("image/*");        startActivityForResult(Intent.createChooser(intent, "选择图片"), SELECT_PICTURE);              }else{              Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);                startActivityForResult(intent, SELECT_CAMER);               }      }     })     .create().show(); 

处理图片，方法一，直接处理返回图片：

注释：

1、网上有说明，直接处理返回的图片是被系统压缩过的，不过自己在测试的过程并没有区别；

2、如果用户不断的重新获取图片的话，必须把现在的Bmp内存释放，否则会报错！ bmp.recycle()。

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {    super.onActivityResult(requestCode, resultCode, data);    if(resultCode == RESULT_OK){     //选择图片     Uri uri = data.getData();      ContentResolver cr = this.getContentResolver();      try {      if(bmp != null)//如果不释放的话，不断取图片，将会内存不够       bmp.recycle();      bmp = BitmapFactory.decodeStream(cr.openInputStream(uri));     } catch (FileNotFoundException e) {      // TODO Auto-generated catch block      e.printStackTrace();     }     System.out.println("the bmp toString: " + bmp);     imageSV.setBmp(bmp);    }else{     Toast.makeText(SetImageActivity.this, "请重新选择图片", Toast.LENGTH_SHORT).show();    }        }

 protected void onActivityResult(int requestCode, int resultCode, Intent data) {    super.onActivityResult(requestCode, resultCode, data);    if(resultCode == RESULT_OK){     Uri uri = data.getData();      String [] proj={MediaStore.Images.Media.DATA};     Cursor cursor = managedQuery( uri,       proj,                 // Which columns to return       null,       // WHERE clause; which rows to return (all rows)       null,       // WHERE clause selection arguments (none)       null);                 // Order-by clause (ascending by name)          int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);     cursor.moveToFirst();          String path = cursor.getString(column_index);     bmp = BitmapFactory.decodeFile(path);     System.out.println("the path is :" + path);    }else{     Toast.makeText(SetImageActivity.this, "请重新选择图片", Toast.LENGTH_SHORT).show();    }        }
