如何通过单击Android教程应用程序中的列表视图全屏打开图像

Question

以下是我到目前为止得到的。该错误是每当我单击ListItem时都会发生以下错误

不幸的是，应用程序已停止工作

列表视图适配器.class

public class ListViewAdapter extends BaseAdapter {
protected static long[] itemVie;
    // Declare Variables
  Context context;
LayoutInflater inflater;

ArrayList<HashMap<String, String>> data;

ImageLoader imageLoader;

HashMap<String, String> resulta = new HashMap<String, String>();

public ListViewAdapter(Context context,

ArrayList<HashMap<String, String>> arraylist) {

this.context = context;
    data = arraylist;

imageLoader = new ImageLoader(context);

}

@Override

public int getCount() {

return data.size();
    }
    @Override

public Object getItem(int position) {
        return null;
    }
    @Override

public long getItemId(int position) {

    return 0;
    }
    @SuppressLint("ViewHolder")

public View getView(final int position, View convertView, ViewGroup parent) {
        // Declare Variables

TextView albname;

ImageView portimages;

inflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

View itemVie = inflater.inflate(R.layout.list_item, parent, false);
        // Get the position


 resulta = data.get(position);
        // Locate the TextViews in listview_item.xml

albname = (TextView) itemVie.findViewById(R.id.name);

portimages = (ImageView) itemVie.findViewById(R.id.portImg);

albname.setText(resulta.get(Portfolio.TAG_TITLE));

imageLoader.DisplayImage(resulta.get(Portfolio.TAG_IMAGE), portimages);


// Capture ListView item click
    itemVie.setOnClickListener(new OnClickListener() {
        @Override
        public void onClick(View arg0) {

resulta = data.get(position);
        Intent intent = new Intent(context, FullScreenImage.class);

intent.putExtra("albname", resulta.get(Portfolio.TAG_TITLE));
                intent.putExtra("portimages",resulta.get(Portfolio.TAG_IMAGE));

context.startActivity(intent);

        }
    });

return itemVie;
    }
}

全屏图像.class

package com.example.truzzapp;
public class FullScreenImage extends Activity implements OnItemSelectedListener {
ImageView image;
TextView txt;
String port_name;
String port_image;
ProgressDialog pDialog;
ImageLoader imageLoader = new ImageLoader(this);
 protected void onCreate(Bundle savedInstanceState) {
       setContentView(R.layout.fullimage);
       Intent i = getIntent();
 port_name = i.getStringExtra("albname");

port_image = i.getStringExtra（"portimages"）;

  txt = (TextView) findViewById(R.id.PortHeading);
           image = (ImageView) findViewById(R.id.portFullImage); 

 txt.setText(port_name);
           imageLoader.DisplayImage(port_image, image);
       }

@Override
public void onItemSelected(AdapterView<?> arg0, View arg1, int arg2,
        long arg3) {
    // TODO Auto-generated method stub
}
@Override
public void onNothingSelected(AdapterView<?> arg0) {
    // TODO Auto-generated method stub
}
 }

Answer 1

注意logcat：did not call through to super.onCreate()

你忘了在setContentView之前打电话给super.onCreate(savedInstanceState);
