编辑:我正在从股票 android 库中检索图像
Intent photoPickerIntent = new Intent(Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
photoPickerIntent.setType("image/*");
photoPickerIntent.putExtra("aspectX", 2);
photoPickerIntent.putExtra("aspectY", 1);
photoPickerIntent.putExtra("scale", true);
photoPickerIntent.putExtra("crop", "true");
photoPickerIntent.putExtra("outputX", 600);
photoPickerIntent.putExtra("outputY", 300);
photoPickerIntent.putExtra("return-data", true);
photoPickerIntent.putExtra(MediaStore.EXTRA_OUTPUT, getTempUri());
photoPickerIntent.putExtra("outputFormat", Bitmap.CompressFormat.JPEG.toString());
startActivityForResult(photoPickerIntent, 100);
