问题
I'm getting the Could not find a method onClick(View) in the activity class android.support.v7.widget.TintContextWrapper for onClick handler on view class android.support.v7.widget.AppCompatButton
exception recently after adding the ability to select a dark or light theme for my app.
I do set the theme in the manifest and then I use following BaseActivity
:
public abstract class BaseActivity extends AppCompatActivity
{
private final int mLightTheme;
private final int mDarkTheme;
public BaseActivity(int lightTheme, int darkTheme)
{
mLightTheme = lightTheme;
mDarkTheme = darkTheme;
}
@Override
protected void onCreate(Bundle savedInstanceState)
{
setTheme(MainApp.getPrefs().darkTheme() ? mDarkTheme : mLightTheme);
super.onCreate(savedInstanceState);
}
}
Any ideas what else could cause this issue? I got the issue from a device running 4.2.2...
NOT working solutions
- similar issues suggest to remove the
theme
tag from the xml file => I'm not using it in my xml, so this is not the case for me

回答1:
Change android.support.v7.widget.AppCompatButton
to Button
.
It will work for u.
Other way.
You can use setOnClickListener
in Your Activity for Click event.
回答2:
For me magically worked setCompatVectorFromResourcesEnabled(true);
like this:
@Override
protected void onCreate(Bundle savedInstanceState) {
AppCompatDelegate.setCompatVectorFromResourcesEnabled(true);
super.onCreate(savedInstanceState);
...
}
Actually, it should be called only once and this could be done in Application class, not necessarily in Activity.
Honestly, I had this code line for other reasons but when tried to remove it, I got exactly this bug with onClick. So I put this line back and wow! Like a charm.
