と から選択した画像をトリミングしようとしGalleryていCameraます。ほとんどの画像をトリミングできません。を呼び出していませんonActivityResult()。以下は私のコードです。OKそして、画像をトリミングした後にクリックするたびに、次のログ猫出力を取得しました。

コード：

private 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, "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("outputX", myImg.getWidth());
        intent.putExtra("outputY", myImg.getHeight());
        intent.putExtra("aspectX", 1);
        intent.putExtra("aspectY", 1);
        intent.putExtra("scale", true);
        intent.putExtra("return-data", true);
        intent.putExtra("outputFormat",
                Bitmap.CompressFormat.PNG.toString());
        intent.putExtra("crop", "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);
        }
    }
}

ソースコード全体を試してみてください。

私は同じプロジェクトを使用しています。そのアクティビティのコードは次のとおりです。

コード：

 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, null );
                        mImageCaptureUri = null;
                    }
                }
            } );

            AlertDialog alert = builder.create();

            alert.show();
        }
    }
}
