我是一名网络开发者,几周前我开始尝试学习android studio和app dev。我目前正在使用kii cloud为我的Android应用程序,我目前正在试图弄清楚如何实现以下场景 -

一个。我已经有用户注册,所以我目前正在编写一个"编辑个人资料"页。

湾在编辑个人资料页面上,我尝试创建一个按钮,以便用户点击它,然后它将打开一个用户可以上传图像的片段。 link

℃。然后将该图像附加到网址,并在需要的位置使用URL,例如视图配置文件页面。链接enter link description here

EditUserProfile.java

public class EditUserProfile extends Activity {
    Button picbutton;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main3);
        picbutton = (Button) findViewById(R.id.MypicButton);

        // Capture button clicks
        picbutton.setOnClickListener(new View.OnClickListener() {
            public void onClick(View arg0) {

        FragmentManager fm = getFragmentManager();
        Fragment fragment = fm.findFragmentById(R.id.fragcon);
        if(fragment == null)
            fragment = new ProfilePic();
        FragmentTransaction ft = getFragmentManager().beginTransaction();
        ft.replace(R.id.fragcon, fragment);
        ft.commit();
            }

        } else {
            showToast("picking file failed!");
        }
    }

    private void showToast(String message) {
        Toast.makeText(this.activity, message, Toast.LENGTH_SHORT).show();
    }

    private String getFilePathByUri(Uri selectedFileUri) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
            // Workaround of retrieving file image through ContentResolver
            // for Android4.2 or later
            String filePath = null;

                if (!cursor.moveToFirst())
                    return null;
                int columnIndex = cursor.getColumnIndex(filePathColumn[0]);
                if (columnIndex < 0) {
                    return null;
                }
                String picturePath = cursor.getString(columnIndex);
                return picturePath;
            } finally {
                cursor.close();
            }
        }
    }

    private void uploadFile(String path) {
        KiiObject object = KiiObject.createByUri(Uri.parse(objectUri));
        File f = new File(path);
        Log.v(TAG, "file can read : " + f.canRead());
        KiiUploader uploader = object.uploader(this.activity, f);
        uploader.transferAsync(new KiiRTransferCallback() {

            @Override
            public void onStart(KiiRTransfer operator) {
                setFragmentProgress(View.VISIBLE);
            }

            @Override
            public void onTransferCompleted(KiiRTransfer operator, Exception e) {
                setFragmentProgress(View.INVISIBLE);
                if (e == null) {

                } else {

                }
            }
        });
    }

    public void moveFromDialogFragment(Class<?> clazz) {
        if (clazz != null) {
            Intent i = new Intent(this.activity, clazz);
            startActivity(i);
        }
    }

    void showAlert(String message) {
        DialogFragment newFragment = AlertDialogFragment.newInstance(
                R.string.operation_failed, message, null);
        newFragment.show(getFragmentManager(), "dialog");
    }

    void setFragmentProgress(int v) {
        ProgressFragment fragment = (ProgressFragment) getFragmentManager()
                .findFragmentById(R.id.progressFragment);
        if (fragment != null && fragment.isInLayout()) {
            fragment.setProgressBarVisiblity(v);
        }
    }

    void setPageImage(int page) {
        ProgressFragment fragment = (ProgressFragment) getFragmentManager()
                .findFragmentById(R.id.progressFragment);
        if (fragment != null && fragment.isInLayout()) {
            fragment.setPageImage(page);
        }
    }
}

然后对于这样的事情,我试图找到一种方法来动态显示与用户关联的个人资料图片,如果不是默认使用图标。

holder.icon.setImageResource(R.drawable.list_account);

UserListLoader.java

public class UserListAdapter extends AbstractArrayAdapter<IUser> {

    private final LayoutInflater inflater;

    public UserListAdapter(Context context) {
        super(context, R.layout.image_list_item);
        this.inflater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    }
    @Override
    public View getView(int position, View convertView, ViewGroup parent) {
        ViewHolder holder;
        if (convertView == null) {
            convertView = this.inflater.inflate(R.layout.image_list_item, parent, false);
            holder = new ViewHolder();
            holder.text = (TextView)convertView.findViewById(R.id.row_text);
            holder.icon = (ImageView)convertView.findViewById(R.id.row_icon);
            convertView.setTag(holder);
        } else {
            holder = (ViewHolder)convertView.getTag();
        }

        IUser user = this.getItem(position);
        holder.position = position;
        holder.text.setText(user.getUsername());
        holder.icon.setImageResource(R.drawable.list_account);
        return convertView;
    }

}

同样在app中打开时,EditUserProfile崩溃了     picbutton.setOnClickListener(new View.OnClickListener()

对此事项的任何指导或帮助表示赞赏。谢谢。
