我有一个应用程序,我可以让用户选择画廊图像或用相机拍照,然后我给他裁剪它的选项。
现在,当用户裁剪图像时,Gallery 裁剪器返回裁剪部分的 ByteArray,是否可以传递一个参数要求 Gallery 裁剪器将输出保存到文件(就像我开始意图在摄像头)
例如:
这是我使用的裁剪代码:
// Initialize intent
Intent intent = new Intent("com.android.camera.action.CROP");
// set data type to be sent
intent.setType("image/*");
// get croppers available in the phone
List<ResolveInfo> list = getPackageManager().queryIntentActivities( intent, 0 );
int size = list.size();
// handle the case if there's no cropper in the phone
if (size == 0) {
Toast.makeText(this, "Can not find image crop app", Toast.LENGTH_SHORT).show();
return;
} else {
// now this is the case if cropper exists
// initialize the Uri for the captures or gallery image
Uri imageUri = Uri.fromFile(new File(mCurrentPhotoPath));
// Send the Uri path to the cropper intent
intent.setData(imageUri);
intent.putExtra("outputX", 200);
intent.putExtra("outputY", 200);
intent.putExtra("aspectX", 1);
intent.putExtra("aspectY", 1);
intent.putExtra("scale", true);
// Here's my attempt to ask the intent to save output data as file
File f = null;
// Here I initialize empty file
try{
// This returns the file created
f = setUpCroppedFile();
mCurrentThumbPath = f.getAbsolutePath();
intent.putExtra(MediaStore.EXTRA_OUTPUT, Uri.fromFile(f));
intent.putExtra("output", Uri.fromFile(f));
}
catch(IOException e){
e.printStackTrace();
}
// --------------------------------------------------------------------
// -----------> When changing this to false it worked <----------------
// --------------------------------------------------------------------
intent.putExtra("return-data", true);
// --------------------------------------------------------------------
// --------------------------------------------------------------------
// If there's only 1 Cropper in the phone (e.g. Gallery )
if (size == 1) {
// get the cropper intent found
Intent i = new Intent(intent);
ResolveInfo res = list.get(0);
i.setComponent( new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
startActivityForResult(i, CROPPED_PHOTO);
}
// Please ignore the case if there are more . . I know how to handle it
更新:问题已解决,我想我会把它留在这里,以防其他人发现它有用(请参阅上面代码中的大注释)
