onClickListener() misses sometimes for ImageView

Question

I am simply using a PNG image as source in ImageView & want to add a onClickListener(). Problem is that button's onClick() doesn't trigger smoothly, means when I click on image sometimes it works fine & sometimes it doesn't work. Even I have added some padding around ImageView to increase the clickable area. I also tried replacing ImageView with ImageButton but no luck. That is also behaving same way. Here is my code:

ImageView back = (ImageView) findViewById(R.id.back);
back.setOnClickListener(new View.OnClickListener() 
{
   public void onClick(final View v) 
   {
     finish() 
   } 
});

XML for button:

<ImageView
android:id="@+id/back"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:scaleType="fitCenter"
android:padding="10dp"
android:src="@drawable/btn_back"/>

Please note that I am using this ImageView in a custom action bar.

Answer 1

1. Size of Image is so small
2. You can use Toolbar instead of custom action bar. You can call: getSupportActionBar().setDisplayHomeAsUpEnabled(true);
