Question

I am trying to launch the mobile network settings screen in android 4.1 with a button click. On the button click I am getting “Could not find a method onOKclicked(View) in the activity class.” My code is below. Any help would be appreciated!

public void onOKclicked (Intent intent){
    startActivityForResult(new Intent(android.provider.Settings.ACTION_NETWORK_OPERATOR_SETTINGS), 0);
    startActivity(intent);
}

<activity android:name="android.provider.Settings.ACTION_NETWORK_OPERATOR_SETTINGS"></activity>

<Button
    android:id="@+id/btnOK"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_centerHorizontal="true"
    android:layout_centerVertical="true"
    android:text="@string/OkButton" 
    android:onClick="onOKclicked" />

Answer 1

It is looking for a function named onOKclicked with a View as parameter (the button)

public void onOKclicked (View v){
    startActivityForResult(new Intent(android.provider.Settings.ACTION_NETWORK_OPERATOR_SETTINGS), 0);
}
