public class TextInterface extends RelativeLayout{

    private topbarClickListener listener;
    private Button mBtn;

    public interface topbarClickListener{

        public void leftClick();
        public void rightClick();
    }

    public void setOnTopBarClickListener(topbarClickListener listener){

        this.listener = listener;
    }

    public TextInterface(Context context, AttributeSet attrs) {
        super(context, attrs);

        mBtn.setOnClickListener(new OnClickListener() {
            @Override
            public void onClick(View v) {
                listener.leftClick();
                listener.rightClick();
            }
        });
    }

}

调用

private TextInterface textInterface;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);


    textInterface.setOnTopBarClickListener(new TextInterface.topbarClickListener() {
        @Override
        public void leftClick() {

        }

        @Override
        public void rightClick() {

        }
    });
