Android 如何将裁剪选项添加到图像拾取

我有这个密码

Intent getIntent = new Intent(Intent.ACTION_GET_CONTENT);
            getIntent.setType("image/*");

            Intent pickIntent = new Intent(Intent.ACTION_PICK, android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            pickIntent.setType("image/*");

            Intent chooserIntent = Intent.createChooser(getIntent, "Select Image");
            chooserIntent.putExtra(Intent.EXTRA_INITIAL_INTENTS, new Intent[] {pickIntent});
            startActivityForResult(chooserIntent, 1);

获取您应该添加的图像后，我应该添加什么来进行裁剪，然后将该库与从

startActivityForResult（）调用中返回的图像一起使用

，并且不要求任何尊重
ACTION\u PICK
、
ACTION\u GET\u CONTENT
或
ACTION\u OPEN\u DOCUMENT
的活动来支持一些未记录的额外活动来为您处理图像裁剪。

您需要这样做

 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, "Can not find image crop app",
                    Toast.LENGTH_SHORT).show();

            return;
        } else {
            intent.setData(mImageCaptureUri);

            intent.putExtra("outputX", 200);
            intent.putExtra("outputY", 200);
            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(

                    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("Choose Crop App");
                builder.setAdapter(adapter,
                        new DialogInterface.OnClickListener() {
                            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);

                alert.show();
            }

    }

你需要像这样

 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, "Can not find image crop app",
                    Toast.LENGTH_SHORT).show();

            return;
        } else {
            intent.setData(mImageCaptureUri);

            intent.putExtra("outputX", 200);
            intent.putExtra("outputY", 200);
            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("Choose Crop App");
                builder.setAdapter(adapter,
                        new DialogInterface.OnClickListener() {
                            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,

                alert.show();
