android调用系统的自定义裁剪后得到的图片不清晰，使用MediaStore.EXTRA_OUTPUT获取缓存下的清晰图片

protected void onActivityResult(int requestCode, int resultCode, Intent data) { switch (requestCode){
case RESULT_CANCELED:
ToastUtil.showCenter(R.string.cancel);
return;
case 111://获取到图片后发送的requestCode，然后现在开始剪切
if (USER_ICON.exists()){
photoClip(Uri.fromFile(USER_ICON), 1, this); }
break; case 1://剪切成功后的返回
Bitmap bitmap = null;
try {
bitmap = BitmapFactory.decodeStream(getContentResolver().openInputStream(tempPhotoUri));
//取出bitmap即可
break; }
super.onActivityResult(requestCode, resultCode, data);
} public void photoClip(Uri uri, int requestCode, Activity a) {
Intent intent = new Intent();//调用系统自带的图片裁剪
intent.setAction("com.android.camera.action.CROP");
intent.setDataAndType(uri, "image/*");
intent.putExtra("crop", "true");//设置在开启的Intent中设置显示的VIEW可裁剪
intent.putExtra("aspectX", 16);//宽高比
intent.putExtra("aspectY", 9);
intent.putExtra("outputX", 1080);
intent.putExtra("outputY", 720);
intent.putExtra("return-data", false);//return置为false，获取截图保存的uri
