Change image On click in dynamic Linear-Layout in adapter

Question

Can you please tell me that how can i change the image of my dynamically created linear layout using v.gettag().I think i need to use another viewHolder to hold the items inside LinearLayout.please have a look on below mentioned piece of code of my adapter class.

here is piece of code :-

viewHolder.imgView.setOnClickListener(new OnClickListener() {

				@Override
				public void onClick(View v) {
					viewHolder.lnrLayout.setVisibility(View.VISIBLE);
					viewHolder.imgView.setVisibility(View.GONE);
					for (int i = 0; i < mList.size(); i++) {
						// TODO creation of buttons and image-views and views
						testText = new TextView(activity);
						testText.setText("TestData");
						mview = new View(activity);

						mImageView = new ImageView(activity);
						mImageView.setImageDrawable(activity.getResources()
								.getDrawable(R.drawable.check));
						mImageView.setPadding(5, 5, 5, 5);
						// TODO Linear-Layout in which they all are binded.
						linearlayout = new LinearLayout(activity);
						linearlayout.setOrientation(LinearLayout.HORIZONTAL);
						LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
								LinearLayout.LayoutParams.MATCH_PARENT,
								LinearLayout.LayoutParams.MATCH_PARENT);
						layoutParams.setMargins(5, 5, 5, 5);
						linearlayout.setLayoutParams(layoutParams);
						linearlayout.setBackground(activity.getResources()
								.getDrawable(R.drawable.background_shapes));
						// TODO setting their respective params.

						LinearLayout.LayoutParams imageParams = new LinearLayout.LayoutParams(
								0, LinearLayout.LayoutParams.MATCH_PARENT,
								0.23f);
						mImageView.setLayoutParams(imageParams);

						LinearLayout.LayoutParams viewParams = new LinearLayout.LayoutParams(
								0, LinearLayout.LayoutParams.MATCH_PARENT,
								0.01f);
						mview.setBackgroundColor(Color.WHITE);
						mview.setLayoutParams(viewParams);

						LinearLayout.LayoutParams TextParams = new LinearLayout.LayoutParams(
								0, LinearLayout.LayoutParams.MATCH_PARENT,
								0.85f);
						testText.setGravity(Gravity.CENTER);
						testText.setLayoutParams(TextParams);
						// TODO Adding to Dynamic Linear-layout.
						linearlayout.addView(testText);
						linearlayout.addView(mview);
						linearlayout.addView(mImageView);
						// TODO Adding to Main Linear-layout


						viewHolder.lnrLayout.addView(linearlayout);
						
								.indexOfChild(linearlayout);
						linearlayout.setTag(Integer.toString(idx));

						linearlayout.setOnClickListener(new OnClickListener() {

							@Override
							public void onClick(View v) {
								String idxStr = (String) v.getTag();
								Toast.makeText(activity, idxStr,
										Toast.LENGTH_SHORT).show();

							}
						});
					}
				}
			});

Second Approach :-

static class ViewHolder {
		TextView tvProductName;
		ImageView imgView;
		View viewRightLine;
		ScrollView scrlLstItems;
		LinearLayout lnrLayout;

	}

	static class InternalViewHolder {
		TextView tvProductName;
		ImageView imgViewProduct;
		View viewdivider;
		LinearLayout mLayout;

	}

	@Override
	public View getView(LayoutInflater inflater, ViewGroup parent) {
		final ViewHolder viewHolder;
		mView = inflater.inflate(R.layout.selector_item_compare, null);
		if (mView != null) {
			viewHolder = new ViewHolder();
			viewHolder.tvProductName = (TextView) mView
					.findViewById(R.id.tv_product);
			viewHolder.imgView = (ImageView) mView
					.findViewById(R.id.img_product);
			viewHolder.viewRightLine = (View) mView
					.findViewById(R.id.view_right_line);
			viewHolder.lnrLayout = (LinearLayout) mView
					.findViewById(R.id.lnr_test);
			viewHolder.tvProductName.setText(Name);
			viewHolder.imgView.setImageResource(Image);
			viewHolder.imgView.setOnClickListener(new OnClickListener() {

				@SuppressWarnings("unused")
				@Override
				public void onClick(View v) {
					viewHolder.lnrLayout.setVisibility(View.VISIBLE);
					viewHolder.imgView.setVisibility(View.GONE);
					for (int i = 0; i < mList.size(); i++) {
						InternalViewHolder holder = null;

						if (holder == null) {
							holder = new InternalViewHolder();
							holder.imgViewProduct = new ImageView(activity);
							holder.tvProductName = new TextView(activity);
							holder.viewdivider = new View(activity);
							holder.mLayout = new LinearLayout(activity);
							// TODO creation of buttons and image-views and
							// views

							holder.imgViewProduct.setImageDrawable(activity
									.getResources().getDrawable(
											R.drawable.check));
							holder.imgViewProduct.setPadding(5, 5, 5, 5);
							// TODO Linear-Layout in which they all are binded.

							holder.mLayout
									.setOrientation(LinearLayout.HORIZONTAL);
							LinearLayout.LayoutParams layoutParams = new LinearLayout.LayoutParams(
									LinearLayout.LayoutParams.MATCH_PARENT,
									LinearLayout.LayoutParams.MATCH_PARENT);
							layoutParams.setMargins(5, 5, 5, 5);
							holder.mLayout.setLayoutParams(layoutParams);
							holder.mLayout.setBackground(activity
									.getResources().getDrawable(
											R.drawable.background_shapes));
							// TODO setting their respective params.

							LinearLayout.LayoutParams imageParams = new LinearLayout.LayoutParams(
									0, LinearLayout.LayoutParams.MATCH_PARENT,
									0.23f);
							holder.imgViewProduct.setLayoutParams(imageParams);
							holder.imgViewProduct.setVisibility(View.GONE);

							LinearLayout.LayoutParams viewParams = new LinearLayout.LayoutParams(
									0, LinearLayout.LayoutParams.MATCH_PARENT,
									0.01f);
							holder.viewdivider.setBackgroundColor(Color.WHITE);
							holder.viewdivider.setLayoutParams(viewParams);
							holder.viewdivider.setVisibility(View.GONE);

							LinearLayout.LayoutParams TextParams = new LinearLayout.LayoutParams(
									0, LinearLayout.LayoutParams.MATCH_PARENT,
									0.85f);
							holder.tvProductName.setGravity(Gravity.CENTER);
							holder.tvProductName.setLayoutParams(TextParams);
							// TODO Adding to Dynamic Linear-layout.
							holder.mLayout.addView(holder.tvProductName);
							holder.mLayout.addView(holder.viewdivider);
							holder.mLayout.addView(holder.imgViewProduct);
							// TODO Adding to Main Linear-layout

							holder.tvProductName.setText(mCategories.get(i)
									.getName());

							viewHolder.lnrLayout.addView(holder.mLayout);
							viewHolder.lnrLayout.setTag(holder);
						} else {
							holder = (InternalViewHolder) viewHolder.lnrLayout
									.getTag();
						}

						// int idx = viewHolder.lnrLayout
						// .indexOfChild(holder.mLayout);
						// holder.mLayout.setTag(Integer.toString(idx));

						holder.mLayout
								.setOnClickListener(new OnClickListener() {

									@Override
									public void onClick(View v) {
										// String idxStr = (String) v.getTag();
										// Toast.makeText(activity, idxStr,
										// Toast.LENGTH_SHORT).show();
										holder.imgViewProduct
												.setVisibility(View.VISIBLE);
										holder.viewdivider
												.setVisibility(View.VISIBLE);

									}
								});
					}
				}
			});
			viewHolder.tvProductName.setOnClickListener(new OnClickListener() {

				@Override
				public void onClick(View v) {
					if (activity.getResources().getBoolean(
							R.bool.landscape_only)) {
						viewHolder.lnrLayout.removeAllViews();
						viewHolder.lnrLayout.setVisibility(View.GONE);
						viewHolder.imgView.setVisibility(View.VISIBLE);
					}

				}
			});
			mView.setTag(viewHolder);

		} else {
			viewHolder = (ViewHolder) mView.getTag();
		}
		return mView;
	}

Answer 1

I tried your second Approach , So if i understand your point that you want to make you check image visible on click and make it again invisible when i click on same button again.So, here i do some necessary changes in your code ...Please have a look on it and tell me if it works or not.........

static class ViewHolder {
		TextView tvProductName;
		ImageView imgView;
		View viewRightLine;
		ScrollView scrlLstItems;
		LinearLayout lnrLayout;

	}

	static class InternalViewHolder {
		TextView tvProductName;
		ImageView imgViewProduct;
		View viewdivider;
		LinearLayout mLayout;

	}

	@Override
	public View getView(LayoutInflater inflater, ViewGroup parent) {
		final ViewHolder viewHolder;
		mView = inflater.inflate(R.layout.selector_item_compare, null);
		if (mView != null) {
			viewHolder = new ViewHolder();
			viewHolder.tvProductName = (TextView) mView
					.findViewById(R.id.tv_product);
			viewHolder.imgView = (ImageView) mView
					.findViewById(R.id.img_product);
			viewHolder.viewRightLine = (View) mView
					.findViewById(R.id.view_right_line);
			viewHolder.lnrLayout = (LinearLayout) mView
					.findViewById(R.id.lnr_test);
			viewHolder.tvProductName.setText(Name);
			viewHolder.imgView.setImageResource(Image);
			viewHolder.imgView.setOnClickListener(new OnClickListener() {

				@SuppressWarnings("unused")
				@Override
