    copied!<p>I want a button in my Settings screen. This exact question has been asked <a href="https://stackoverflow.com/questions/10514005/add-a-button-into-prefrencescreen-android">here</a>. But unfortunately has no answers. :( </p> <p><img src="https://i.stack.imgur.com/4qKrf.png" alt="enter image description here"></p> <p>In order to get to this, I created a custom preference like this - </p> <pre><code> public class CustomPreference extends Preference { private LinearLayout mWidgetContainer; private View mRowView; public CustomPreference(Context context) { super(context); } public CustomPreference(Context context, AttributeSet attrs) { super(context, attrs); } public CustomPreference(Context context, AttributeSet attrs, int defStyle) { super(context, attrs, defStyle); } @Override protected View onCreateView(ViewGroup parent) { LayoutInflater viewInflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE); mRowView = viewInflater.inflate(R.layout.preferences_row_view, parent, false); mWidgetContainer = (LinearLayout) mRowView.findViewById(android.R.id.widget_frame); Button button = new Button(getContext()); LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT); button.setLayoutParams(params); button.setBackgroundResource(R.drawable.listview_row_bg); button.setTextSize(14); button.setPadding(5, 5, 5, 5); button.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { Intent intent = new Intent(getContext(), BuyScreenActivity.class); getContext().startActivity(intent); } }); button.setTypeface(null, Typeface.BOLD); button.setText("Buy now"); mWidgetContainer.addView(button); return mRowView; } } </code></pre> <p>This does work. But it behaves strange. As you can see on click of that button I'm taking the user to Activity called <code>BuyScreenActivity</code>. The strange part is when I press back on <code>BuyScreenActivity</code>, I come back to my Settings screen but <code>onDestroy</code> and <code>onStop</code> of <code>BuyScreenActivity</code> is not called at all. Why would it behave that way? </p> <p>If I scroll down the settings screen, <code>onStop</code> &amp; <code>onDestroy</code> will then be called. Why does this have to behave that way? </p>
