我想从图库或相机中获取图像，然后我想以特定的高宽比剪裁它。 但是这段代码在棒棒糖版本中工作，而它在KitKat中有效。 任何人都可以帮助解决这个问题。剪裁不适用于Nexus 5，设备版本5.1.1
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);
