у меня естьonClickListener установить наTextView (mReadAgainButton), который должен перезагрузить набор инструкций с самого начала (первоначально отображается черезonClickListener наButton называетсяmAssistUpdateButton) однако при нажатии наTextView mReadAgainButton кажется, ничего не происходит.

public void onClick(View v) {
        if (v == mAssistUpdateButton) {

            // Update button for ICS and up is selected
            // Get the TextView in the Assist Update UI

            CharSequence styledText = text;
            switch (mInstructionNumber) {

            case 0:
                // Retrieve the instruction string resource corresponding the
                // 2nd set of instructions
                text =   String.format(getString(R.string.apn_app_text_instr),
                        TotalSteps);
                styledText = Html.fromHtml(text);
                // Update the TextView with the correct set of instructions
                tv.setText(styledText);
                // Increment instruction number so the correct instructions
                // string resource can be retrieve the next time the update
