作物不适合画廊图像工作 [英] Crop does not work for gallery images
本文介绍了作物不适合画廊图像工作的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我使用下面的code作物从相机和画廊图像：
I am using the following code to crop images from camera and gallery :
private void doCrop() {
final ArrayList<CropOption> cropOptions = new ArrayList<CropOption>();
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, getApplicationContext().getString(R.string.crop_unavailable), Toast.LENGTH_SHORT).show();
// return
} else {
intent.setData(mImageCaptureUri);
int y = 200;
if(lastSelect == 1 || lastSelect == 2 || lastSelect == 3 || lastSelect == 4){
y = (int) (200 * 0.5697329376854599);
}
intent.putExtra("outputX", 200);
intent.putExtra("outputY", y);
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_FROM_CAMERA);
} else {
for (ResolveInfo res: list) {
final CropOption co = new CropOption();
co.title = getPackageManager().getApplicationLabel(res.activityInfo.applicationInfo);
co.icon = getPackageManager().getApplicationIcon(res.activityInfo.applicationInfo);
co.appIntent = new Intent(intent);
co.appIntent.setComponent(new ComponentName(res.activityInfo.packageName, res.activityInfo.name));
cropOptions.add(co);
}
CropOptionAdapter adapter = new CropOptionAdapter(getApplicationContext(), cropOptions);
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setTitle(getApplicationContext().getString(R.string.select_crop_app));
builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int item) {
startActivityForResult(cropOptions.get(item).appIntent, CROP_FROM_CAMERA);
}
});
builder.setOnCancelListener(new DialogInterface.OnCancelListener() {
@Override
public void onCancel(DialogInterface dialog) {
if (mImageCaptureUri != null) {
getContentResolver().delete(mImageCaptureUri, null, null);
mImageCaptureUri = null;
}
}
});
AlertDialog alert = builder.create();
alert.show();
}
}
}
尽管作物从相机中的照片好了，它不画廊图像工作。它总是返回从图库中选择基本画面。
While it crops pictures from camera well, it doesn't work on gallery images. It always returns basic picture selected from gallery.
onActivityResult
if (resultCode != RESULT_OK)
return;
switch (requestCode) {
case PICK_FROM_CAMERA:
doCrop();
break;
case PICK_FROM_FILE:
mImageCaptureUri = data.getData();
doCrop();
break;
case CROP_FROM_CAMERA:
Bundle extras = data.getExtras();
if (extras != null) {
photo = extras.getParcelable("data");
// imgImage4.setImageBitmap(photo);
int w = (int) (UIHelpers.width * 0.15);
File f = new File(mImageCaptureUri.getPath());
if (f.exists()) {
// f.delete();
}
String imageDir = getRealPathFromURI(mImageCaptureUri);
txtSelectLogoNj.setVisibility(View.GONE);
rlLogoNj.setVisibility(View.VISIBLE);
image5 = imageDir;
App.sharedpreferences = getSharedPreferences(App.MyPREFERENCES, Context.MODE_PRIVATE);
App.editor = App.sharedpreferences.edit();
App.editor.putString("IMAGE5", imageDir);
App.editor.commit();
}
}
break;
}
如何解决呢？
How do I fix it?
推荐答案
试试这个工作code
Try this Working code
Buttonclick拿相机
Buttonclick to take camera
dialog.show();
添加这里面的onCreate（）
Add this inside Oncreate()
captureImageInitialization();
试试这个它会工作
try this it will work
// for camera
private void captureImageInitialization() {
try {

* a selector dialog to display two image source options, from
* camera ‘Take from camera’ and from existing files ‘Select from
* gallery’
