我有代码来裁剪图像,如下所示:

public void doCrop(){
Intent intent = new Intent("com.android.camera.action.CROP");
intent.setType("image/");
List<ResolveInfo> list = getPackageManager().queryIntentActivities(intent,0);
int size = list.size();
if (size == 0 ){
   Toast.makeText(this, "Cant find crop app").show();
   return;
} else{
   intent.setData(selectImageUri);
   intent.putExtra("outputX", 300);
   intent.putExtra("outputY", 300);
   intent.putExtra("aspectX", 1);
   intent.putExtra("aspectY", 1);
   intent.putExtra("scale", true);
   intent.putExtra("return-data", true);
   if (size == 1) {
       Intent i = new Intent(intent);
       ResolveInfo res = list.get(0);
       i.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
       startActivityForResult(i, CROP_RESULT);
   }
}
}

public void onActivityResult (int requestCode, int resultCode, Intent dara){
   if (resultCode == RESULT_OK){
      if …
