Android 5 And Onclick In Xml Layout

I have set android:onclick in xml for an imageButton and put that method in my activity. In android s below 5 it works fine but in android 5 it gives me Error. My imageButton code:

Solution 1:

I had a very similar problem, it happens only on Android Lollipop, whilst it works fine on the older versions. Looks like a bug or undocumented feature in 5.0.

Make sure that in the layout file where your ImageButton resides there is noandroid:theme set, i.e. nothing like this:

android:theme="@style/Base.Theme.AppCompat.Light"

Instead, define your application theme in AndroidManifest.xml application element:

<application...android:theme="@android:style/Theme.Holo.Light"...  >

Solution 2:

i can't find what is the real problem, maybe some incompatiblity between eclipse and api 21 or something else.

for now i just set an onClickListener for that button.

Solution 3:

finally i found the problem.

all i need is to associate the xml layout to an activity. for this in the design tab of xml layout make sure you selected the right activity.

Solution 4:

It happens when you have declared the public void onClick(View view) method inside the fragment instead of activity

Solution 5:

Be sure that your onClick method

publicvoidphotoDetailButtonMethod(View theButton)
{
  //something
}

is written outside onCreate() method and in your Activity class.
