Listview with Details

问题:

i have a Listview which displays list of clients, i have added an onClickListner to Listview so that i can get the detailed information of clicked client.

ListView l = (ListView) findViewById(R.id.jl);
l.setOnItemClickListener(new AdapterView.OnItemClickListener() {
                             @Override
                             public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                                 ClientListView j = JList.get(position);
                                 String mess = "you clicked position " + position + " With Name " + j.GetClientName();
                                 Toast.makeText(Home.this,mess,Toast.LENGTH_LONG).show();
                             }
                         }


);
}

i want to display information but not in toast, i will prefer some activity,fragment or some popup king of thing.

If you want to pass Client Name which you are displaying in list, you can get id from adapter and use it.

@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
        long id) {
        String clientName= (String) ((TextView) view
                .findViewById(R.id.client_name)).getText();
        Intent intent = new Intent(this, NextActivity.class);
          intent.putExtra("client", clientName);
            startActivity(intent);

        }
    } 
}

Use ths code:

l.setOnItemClickListener(new OnItemClickListener() {

        @Override
        public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                long arg3) {
            // TODO Auto-generated method stub
            ClientListView j = JList.get(position);
            String mess = "you clicked position " + position + " With Name " + j.GetClientName();
            AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(ActivityName.this);//Your activity name

    // set title
    alertDialogBuilder.setTitle("Hello!");

    // set dialog message
    alertDialogBuilder.setMessage(mess)
            .setCancelable(false)
            .setPositiveButton("OK", new DialogInterface.OnClickListener() {
                public void onClick(DialogInterface dialog, int id) {
                    // if this button is clicked, close
                    // current activity
                }
            });

    // create alert dialog
    AlertDialog alertDialog = alertDialogBuilder.create();

    // show it
    alertDialog.show();
        }
    });

Hope this will work..

                         @Override
                         public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
                             ClientListView j = JList.get(position);
                             Intent intent = new Intent(this, SecondActivity.class);
                             intent.putExtra("Keyname", j);
                             startActivity(intent);
                         }
                     }
);
}

You can get the intent value in another activity.

回答4:

If I have understood, you want to send some information to another activity to display this information.

You can have a look to the "Intent" in Android. It's used to start a component like an activity and can carry information to this new activity to start.

Intent i = new Intent(ActivityA.this, ActivityB.class);
i.putExtra("CUSTOMER_INFO", customer.getName());
startActivity(i);

Note: If you want to pass a custom object between activities, like for instance a List of custom object :

List<'CustomObject'>

Your custom object class have to implement Parcelable.
