Could not find a method onClick(View) in the activ

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.
