Question

I am working on an Android application.In my main activity i have to implement a list.The following is the sample shape of my page

|----------------------| \
|  |Button|            |  \
|----------------------|   \                  
|listview row1         | \   \
|listview row1         |  \   \---------Screen
|listview row1         | / --/----- ListView 
|                      |/   /
|                      |  /
|                      | /
|______________________|/

The button is in my activity page and listview rows are creating in baseadapter.Listview is containing a textview.Now I have to change the Textviews background color when I click the button from activity and next time I click the button the textviews color will retain the old color.How can I do it friends?. I declared textview in getview() method.

Answer 1

At last I got the solution.It may helpful to others.But I am not about the quality of my code.

step 1)

I craete variable in my activity

static int hidestate=0;

And in the hide buttons on click method I write this

hide_btn.setOnClickListener(new OnClickListener() {

        @Override
        public void onClick(View v) {
            // TODO Auto-generated method stub

            if (hidestate==0) {

                hidestate=1;

                sMSConversationAdapter.notifyDataSetChanged();
                hide_btn.setText("Show All");

            }else {
                hidestate=0;

                sMSConversationAdapter.notifyDataSetChanged();
                hide_btn.setText("Hide All");
            }

        }
    });

Step 2)
The following is my BaseAdapter class getView()

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

    View vi=convertView;
    final TextView message;

    if(convertView==null)
        vi = inflater.inflate(R.layout.smsconversation_row, null);

    RelativeLayout nws=(RelativeLayout)vi.findViewById(R.id.all);
    message=(TextView)vi.findViewById(R.id.snt_txt);

    if (SMSConversationHome.hidestate==1) {
        message.setVisibility(View.INVISIBLE);

    }
    else{

        message.setVisibility(View.VISIBLE);

    }
}

Thank you friends For yours help.
