        list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override

            // write your start another activity code here
            switch(i){
            case 0:{
                Intent intent1 = new Intent(LeftAndRightActivity.this, DisplayActivity.class);
                startActivity(intent1);
            }
            }
        }
    });

rightlistfragment.xml

public class RightListFragment extends ListFragment {

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    return inflater.inflate(R.layout.rightlist, null);

}

public void onActivityCreated(Bundle savedInstanceState) {
    super.onActivityCreated(savedInstanceState);
    SampleAdapter adapter = new SampleAdapter(getActivity());
    adapter.add(new SampleItem("a"));
    adapter.add(new SampleItem("b"));
    adapter.add(new SampleItem("c"));
    adapter.add(new SampleItem("d"));
    adapter.add(new SampleItem("e"));
    adapter.add(new SampleItem("f"));
    setListAdapter(adapter);

    list.setOnItemClickListener(new AdapterView.OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> adapterView, View view, int i, long l) {
            // write your start another activity code here
            switch(i){
            case 0:{
                startActivity(new Intent(RightListFragment.this,FragmentBindAcc.class));
            }
            }
        }       

    TextView text1 = (TextView) getView().findViewById(R.id.loginName);

    text1.setText("TEST");
}

private class SampleItem {
    public String tag;
    public int iconRes;
    public SampleItem(String tag) {
        this.tag = tag; 

    }
}

public class SampleAdapter extends ArrayAdapter<SampleItem> {

    public SampleAdapter(Context context) {
        super(context, 0);
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        if (convertView == null) {
            convertView = LayoutInflater.from(getContext()).inflate(R.layout.rightrow, null);
        }
        ImageView icon = (ImageView) convertView.findViewById(R.id.arrow);
        icon.setImageResource(getItem(position).iconRes);
        TextView title = (TextView) convertView.findViewById(R.id.row_title);
        title.setText(getItem(position).tag);


        return convertView;
    }

}
   }

推荐答案

您可以通过 setOnItemClickListener 的的ListView得到这个如下：

list.setOnItemClickListener(new OnItemClickListener() {
        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,long arg3) {
            // TODO Auto-generated method stub
            switch(arg2){
            case 0:{  

                    startActivity(new Intent(getApplicationContext(),ActivityA.class));                     
                }
            break;  
            case 1:{

                    startActivity(new Intent(getApplicationContext(),ActivityB.class));
                                    }   
            break;
            case 2:{  
                ExampleQuestion.topicNo=3;                          
                startActivity(new Intent(getApplicationContext(),ActivityC.class));                     
            }
            break;              
}

您可以把它作为列表视图包含A，B和C.当用户选择一个，它为0的情况和对B案例2和C外壳3。

You can think of it as the listview contains A, B and C. When user selects A, it is the Case 0 and for B Case 2 and for C case 3.
