Question

的问题： 的我从画廊中取出图像，然后在所有设备中裁剪该图像并使其工作完美。但它在Nexus 7 kitkat中运行时给出了错误，因为我已经通过“Gallery Stopped”错误检查了它的构建版本。我已经实现了代码，清单文件中的所有其他必要权限仍然没有得到响应。所以有人可以解决这个问题吗？

这是我的代码：

 final String[] items = new String[] { "Take from camera",
            "Select from gallery" };
    ArrayAdapter<String> adapter = new ArrayAdapter<String>(this,
            android.R.layout.select_dialog_item, items);
    AlertDialog.Builder builder = new AlertDialog.Builder(this);

    builder.setTitle("Select Image");
    builder.setAdapter(adapter, new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface dialog, int item) { // pick from
                                                                // camera
            if (item == 0) {
                Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);

                mImageCaptureUri = Uri.fromFile(new File(Environment
                        .getExternalStorageDirectory(), "tmp_avatar_"
                        + String.valueOf(System.currentTimeMillis())
                        + ".jpg"));

                intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,
                        mImageCaptureUri);

                try {
                    intent.putExtra("return-data", true);

                    startActivityForResult(intent, PICK_FROM_CAMERA);
                } catch (ActivityNotFoundException e) {
                    e.printStackTrace();

            AlertDialog alert = builder.create();

            alert.show();
        }
    }

的 CropAction： 的

 public class CropOption {
  public CharSequence title;
  public Drawable icon;
  public Intent appIntent;
 }

的 CropOptionAdapter.java 的

public class CropOptionAdapter extends ArrayAdapter<CropOption> {
private ArrayList<CropOption> mOptions;
private LayoutInflater mInflater;

public CropOptionAdapter(Context context, ArrayList<CropOption> options) {
    super(context, R.layout.crop_selector, options);

    mOptions = options;

    mInflater = LayoutInflater.from(context);
}

@Override
public View getView(int position, View convertView, ViewGroup group) {
    if (convertView == null)
        convertView = mInflater.inflate(R.layout.crop_selector, null);

    CropOption item = mOptions.get(position);

    if (item != null) {
        ((ImageView) convertView.findViewById(R.id.iv_icon))
                .setImageDrawable(item.icon);
        ((TextView) convertView.findViewById(R.id.tv_name))
                .setText(item.title);

        return convertView;
    }

    return null;
}
    }

我已经解决了我的问题。

我做了什么，

我刚刚从

更改此内容

 intent = new Intent(Intent.ACTION_OPEN_DOCUMENT);
 intent.addCategory(Intent.CATEGORY_OPENABLE);
 intent.setType("*/*");
 startActivityForResult(Intent.createChooser(intent, "Complete action using"), PICK_FROM_FILE);

到

 intent = new Intent(Intent.ACTION_PICK);
 intent.setType("*/*");
 intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT,
                            mImageCaptureUri);
 startActivityForResult(Intent.createChooser(intent,"Complete action using"), PICK_FROM_FILE);

像魅力一样工作。

谢谢大家。
