This is my xml, this is located inside a fragment that appears in my activity.
<FrameLayout
android:id="@+id/frame1"
android:layout_width="wrap_content"
android:layout_height="115dp"
android:layout_margin="2dp"
android:layout_weight="0.33">
<ImageView
android:id="@+id/whoamiwith"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:scaleType="fitCenter"
android:src="@drawable/default_image" />
</FrameLayout>
And this is my java code :
@Override
public void onClick(View click) {
if (click == profileBtn) {
whoamiwith.setBackgroundResource(R.drawable.image_i_wanna_put);
}
}
I am trying to change the image source of the image view. There are no syntax errors but when I click the button the emulator is giving me a force close and on the logcat it says:
java.lang.NullPointerException
It's pointing to the line:
whoamiwith.setBackgroundResource(R.drawable.loginbtn);
whoamiwith.setImageResource(R.drawable.loginbtn);
