调用系统拍照功能：
1 Intent cameraintent = new Intent( 2 MediaStore.ACTION_IMAGE_CAPTURE); 3 // 指定调用相机拍照后照片的储存路径 4 cameraintent.putExtra(MediaStore.EXTRA_OUTPUT, 5 Uri.fromFile(tempFile)); 6 startActivityForResult(cameraintent, 7 PHOTO_REQUEST_TAKEPHOTO);
调用系统相册功能：
1 Intent getAlbum = new Intent(Intent.ACTION_GET_CONTENT);
2 getAlbum.setType("image/*");
3 startActivityForResult(getAlbum, PHOTO_REQUEST_GALLERY);
调用系统裁剪功能：
1 private void startPhotoZoom(Uri uri) { 2 Intent intent = new Intent("com.android.camera.action.CROP"); 3 intent.setDataAndType(uri, "image/*"); 4 // crop为true是设置在开启的intent中设置显示的view可以剪裁 5 intent.putExtra("crop", "true"); 6 7 // aspectX aspectY 是宽高的比例 8 intent.putExtra("aspectX", 1); 9 intent.putExtra("aspectY", 1); 10 11 // outputX,outputY 是剪裁图片的宽高 12 intent.putExtra("outputX", 300); 13 intent.putExtra("outputY", 300); 14 intent.putExtra("return-data", true); 15 intent.putExtra("noFaceDetection", true); 16 System.out.println("22================"); 17 startActivityForResult(intent, PHOTO_REQUEST_CUT); 18 }
