  1. POhow to access to a specific element of every grid view item
    text
    copied!<p>I have a gridview in which there are two elements in each of its items, the first is an image and the second is a title, the title is invisible in the launching of the application, but I have a button outside the grid view that when I click on it, I want to change the visibility of the titles of items to become visible, my problem is that I can not access each title of each item in the grid view. When I set the visibility of the titles (TextView) in the onClick method of the independent button in my activity, it changes the visibility ONLY for the FIRST item in the grid view!</p> <p>This sketch represent my interface, so the titles are invisible in the beginning, but when i click on "SetVisibilityButton", i want to set them to Visible :</p> <pre><code> Image1 Image2 Image3 Title1 Title2 Title3 Image4 Image5 Image6 Title4 Title5 Title6 Image7 Image8 Image9 Title7 Title8 Title9 ---------------------------- SetVisibilityButton ____________________________ </code></pre> <p>I set the grid view in my oncreate() activity :</p> <pre><code> favorGrid = (GridView) findViewById(R.id.favorGrid); favorGrid.setAdapter(adapter); </code></pre> <p>In my ImageAdapter class, this is my getView() method :</p> <pre><code> @Override public View getView(int position, View convertView, ViewGroup parent) { View MyView = convertView; /*we define the view that will display on the grid*/ //Inflate the layout LayoutInflater li = getLayoutInflater(); MyView = li.inflate(R.layout.favor_item, null); // Add The Text!!! TextView tv = (TextView)MyView.findViewById(R.id.title); tv.setText(mTitles[position]); // Add The Image!!! ImageView iv = (ImageView)MyView.findViewById(R.id.favor_item_image); iv.setImageResource(mThumbIds[position]); return MyView; } </code></pre> <p>To get the title textview from my main activity and set his visibility, I tried :</p> <pre><code> TextView title = (TextView) findViewById(R.id.title); title.setVisibility(View.VISIBLE); </code></pre> <p>and tried :</p> <pre><code> // gv is the gridview (R.id.gridview) TextView title = (TextView)gv.findViewById(R.id.title); title.setVisibility(View.VISIBLE); </code></pre> <p>and tried :</p> <pre><code> LinearLayout layout = (LinearLayout) findViewById(R.id.gridLayout); TextView title = (TextView)layout.findViewById(R.id.title); title.setVisibility(View.VISIBLE); </code></pre> <p>But all these solutions set the visibility for only the first element in the grid view.</p> <p>I spent a lot of time with this problem but I don't yet found a solution, does anyone could help me to fix it please thank you in advance</p>
