Question

I want to implement a click listener for a button on my main view. My code is something like below

protected void onCreate(Bundle savedValues) {
    ...
    // Capture our button from layout
    Button button = (Button)findViewById(R.id.btnFinish);
    // Register the onClick listener with the implementation above
    button.setOnClickListener(mFinishListener);
    ...
}

private OnClickListener mFinishListener = new OnClickListener() {
    public void onClick(View v) {
      // do something when the button is clicked
    }
};

But shows me error as follows

The method setOnClickListener(View.OnClickListener) in the type View is not applicable for the arguments (DialogInterface.OnClickListener)  MobileTrackerActivity.java  /MobileTracker/src/com/example/mobiletracker    line 37 Java Problem

I have no idea what to do. Please help.

Answer 1

You are not using the correct interface to instantiate the mFinishLinstener variable…

It is possible you have an import specifying DialogInterface and that is confusing the view.

Try specifying View.OnClickListener explicitly.

private View.OnClickListener mFinishListener = new View.OnClickListener() {
    public void onClick(View v) {
      // do something when the button is clicked
    }
};
