Re: [android-developers] Re: Allow button inside listview to be clickable

The click event is occurring as I tested with a toast message.

The problem seems to be with Background Resource.

Here is the code that I use to create the button:

Button button = new Button(this.mContext);
            button.setId(10000+columnIndex);
            button.setTextSize(TypedValue.COMPLEX_UNIT_DIP, 20);
            button.setGravity(Gravity.CENTER);
            button.setText(item);
            button.setLayoutParams(new ViewGroup.LayoutParams(LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT));           
            button.setBackgroundDrawable(this.mButtonBackground);
            button.setTextColor(Color.WHITE);
            button.setClickable(true);
            button.setFocusable(true);
            button.setOnClickListener(new OnClickListener() {
               
                public void onClick(View arg0) {
                    Toast toast = Toast.makeText(arg0.getContext(), "Clicked", 5);
                    toast.show();
                   
                }
            });
            container.addView(button);

Here is how I get the drawable:
this.mButtonBackground = this.mResources.getDrawable(R.drawable.schedule_button);


And here is the code from schedule_button.xml:

<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">

    <item android:state_pressed="true">
        <shape android:shape="rectangle">
            <solid android:color="@color/gray" />
            <stroke android:width="1dp" android:color="@color/black"/>
        </shape>
    </item>
    <item android:state_focused="true">
        <shape android:shape="rectangle">
            <solid android:color="@color/gray" />
            <stroke android:width="1dp" android:color="@color/black"/>
        </shape>
    </item>
    <item>
        <shape android:shape="rectangle">
            <solid android:color="#00000000" />
            <stroke android:width="1dp" android:color="#00000000"/>
        </shape>
    </item>

</selector>


How can I give any visual feedback to the button's click event?


Thanks.

The problem is, the button is not clickable and doesn't change its state (at least visually as configured on Background Resource).

• Try setting the android:focusable and android:focusableInTouchMode attributes to false. 
  
• Also, have you verified the button is not clickable?  Put a simple click listener on the button that displays a toast message to be sure... It may just be a problem with your background resource. 
  
• Lastly, it may be a problem with having a horizontal scrolling widget inside a vertically scrolling widget but again, I'm not sure about that.  The horizontal scrollview may be stealing the touch events from the buttons...

If I understand correctly, you should simply add android:clickable="true" to your list item

Hi,

I needed to create kind of a sub-list that allows horizontal scrolling, so I created the following structure inside my ListViewItem template:

<HorizontalScrollView android:id="@+id/schedule_scrollView" ... >
        <LinearLayout android:id="@+id/schedule_minutes" ... >
               


                    </LinearLayout>
    </HorizontalScrollView>

And I added dynamically several buttons to this LinearLayout (schedule_minutes), which uses a Background Resource to indicate the button state. The problem is, the button is not clickable and doesn't change its state (at least visually as configured on Background Resource).

How can I fix this?
