Wrap_contents or DP for ImageView


Wrap_contents or DP for ImageView

By : Jakub Cieślik

I think the issue was by ths following , I think if you use wrap_content, then the system will choose the resource from the appropriate resource folder depending on the screen density (mdpi, hdpi, xhdpi, etc) and will use the px dimension of that resource. Since the screen density resource folders (mdpi, hdpi, etc) can each apply to various screen densities (ie, mdpi is ~160dpi, but can be a bit less or a bit more before hitting the next density), this means that the image may change size slightly on different screens. If you specify the actual dp value for height and width, then you ensure the image will scale to maintain the same physical size on all devices.

I think the issue was by ths following , Seems like the bounding box is not correctly calculated when using italic.
Have you tried to use paddingLeft=6 and paddingRight=6 for the elements? (less chance of overlap).

To fix this issue You should be able to access the pieces variable inside the Runnable (because it is final), what you won't be able to access is the i variable. You can do this: final int index = i and use index instead of i inside the run() method. Also, you may want to increase the delay for each image, otherwise all the operations will be executed almost at the same time.
code :
for(int i = 0; i < pieces.length; i++) {
        final int index = i;
        Runnable shuffle = new Runnable() {
            public void run() {
                playLevel(pieces[index]);
            }
        };
        handler.postDelayed(shuffle, (i+1)*3000);
}

    imageView.setOnClickListener(new View.OnClickListener() {

        @Override
        public void onClick(View arg0) {
            Intent myIntent = new Intent(getApplicationContext(), FullscreenImageActivity.class);
            myIntent.putExtra("Drawable", R.drawable.killa_ahmednagar_bhuikot_fort);
            startActivity(myIntent);
        }
    });
    Intent intent = getIntent();
    int drawable = intent.getIntExtra("Drawable", 0); 
    imageView.setImageResource(drawable);

will be helpful for those in need First Add a interface in your adapter class like & use it like this ::
code :
public class SongAdapter extends BaseAdapter {

    Context context;
    private ArrayList<SongModel> songsListDat = null;
    public ArrayList<SongModel> songsList;
    public OnMusicListener mListener;
    private static LayoutInflater inflater;

    public SongAdapter(Activity activity, ArrayList<SongModel> songsListDat, OnMusicListener mListener) {

        this.context = activity;
        this.mListener = mListener;
        this.songsListDat = songsListDat;
        this.songsList = new ArrayList<SongModel>();
        this.songsList.addAll(songsListDat);
    }

    public void setSelectedIndex(int ind) {
        notifyDataSetChanged();
    }

    @Override
    public int getViewTypeCount() {

        return 1;
    }

    @Override
    public int getCount() {
        return songsListDat.size();
    }

    @Override
    public Object getItem(int position) {
        return songsListDat.get(position);
    }

    @Override
    public long getItemId(int position) {
        return position;
    }

    @Override
    public int getItemViewType(int position) {

        return position;
    }

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

        inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View vi = convertView;
        if (convertView == null)
            vi = inflater.inflate(R.layout.ringtone_row_layout, null);

        TextView title = (TextView) vi.findViewById(R.id.name); // title
        ImageView play = (ImageView) vi.findViewById(R.id.imgPlayPause);
        ImageView pause = (ImageView) vi.findViewById(R.id.imgPause);


        SongModel song = new SongModel();
        song = songsListDat.get(position);
        title.setText(song.getSongTitle());

        play.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mListener.onPlayClicked(position);
            }
        });
        pause.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                mListener.onPauseClicked(position);
            }
        });

        return vi;
    }

    public interface OnMusicListener {
        void onPauseClicked(int position);

        void onPlayClicked(int position);
    }
}
songAdapter = new SongAdapter(this, songsList,this);
setListAdapter(songAdapter);
public class MainActivity extends ListActivity implements SongAdapter.OnMusicListener{

    public static final String TAG = "[MainActivity]";

    Activity activity;
    SongAdapter songAdapter;
    SongsManager songsManager = new SongsManager();
    MediaPlayer mp;

    // Songs list
    public ArrayList<SongModel> songsList = new ArrayList<>();
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);


        activity = MainActivity.this;


        mp = new MediaPlayer();


        SongsManager plm = new SongsManager(activity);
        final ArrayList<SongModel> songsListData = songsManager.songList;


        this.songsList = plm.getAllSongs();


        for (int i = 0; i < songsListData.size(); i++) {
            SongModel song = songsListData.get(i);
            songsListData.add(song);
        }


        songAdapter = new SongAdapter(this,songsList,this);
        setListAdapter(songAdapter);

        ListView lv = getListView();

    }

    @Override
    public void onPauseClicked(int position){

          //Todo-- Add code you want to perform on Pause clicked with   specific position

    }
    @Override
    public onPlayClicked(int position){
         //Todo-- Add code you want to perform on Play clicked with   specific position
    }
}
