無法在Nexus 5，設備版本5.1.1中進行裁剪

Question

我想從圖庫或照相機中獲取圖像，然后以特定的縱橫比進行裁剪。 但是此代碼在Lollipop版本中有效，而在KitKat中有效。 任何人都可以請幫助者來解決此問題。

public class MainActivity extends Activity {
private static final int PICK_FROM_CAMERA = 1;
private static final int PICK_FROM_GALLERY = 2;
ImageView imgview;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    imgview = (ImageView) findViewById(R.id.imageView1);
    Button buttonCamera = (Button) findViewById(R.id.btn_take_camera);
    Button buttonGallery = (Button) findViewById(R.id.btn_select_gallery);
    buttonCamera.setOnClickListener(new View.OnClickListener() {

        public void onClick(View v) {
    // call android default camera
            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

            intent.putExtra(MediaStore.EXTRA_OUTPUT,
                    MediaStore.Images.Media.EXTERNAL_CONTENT_URI.toString());
                    // ******** code for crop image
            intent.putExtra("crop", "true");
            intent.putExtra("aspectX", 2);
            intent.putExtra("aspectY", 2);
            intent.putExtra("outputX", 150);
            intent.putExtra("outputY", 150);


            intent.putExtra("return-data", true);
            startActivityForResult(intent, PICK_FROM_CAMERA);


        }
    });
    buttonGallery.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View v) {
            //// //TODO Auto-generated method stub
            Intent intent = new Intent();
            // call android default gallery
            intent.setType("image/*");
            intent.setAction(Intent.ACTION_GET_CONTENT);
            // ******** code for crop image
            intent.putExtra("crop", "true");
            intent.putExtra("aspectX", 2);
            intent.putExtra("aspectY", 2);
            intent.putExtra("outputX", 150);
            intent.putExtra("outputY", 150);


            try {

                intent.putExtra("return-data", true);
                startActivityForResult(Intent.createChooser(intent,
                        "Complete action using"), PICK_FROM_GALLERY);

            } catch (ActivityNotFoundException e) {
                // Do nothing for now
            }
        }
    });
}

protected void onActivityResult(int requestCode, int resultCode, Intent data) {

    if (requestCode == PICK_FROM_CAMERA) {
        Bundle extras = data.getExtras();

        Bitmap photo = extras.getParcelable("data");
        imgview.setImageBitmap(photo);


    }

    if (requestCode == PICK_FROM_GALLERY) {
        Bundle extras2 = data.getExtras();
        if (extras2 != null) {
            Bitmap photo = extras2.getParcelable("data");
            imgview.setImageBitmap(photo);

        }
    }
}

}

Answer 1

您必須在最后一部分中將extras2作為null正確嗎？

我也一樣！ 您能解釋一下到底發生了什么嗎？ 它會導致“照片”應用崩潰，還是在imageView中看不到更新？
