Onclick To Call Interface Method From Mainactivity

I need to perform onClick to call the onItemSelected listener method of another class.I don't know how to call that method in Image button onClick listener.So that it will move to

Solution 1:

You may create your own listener and add the block of code that you want to execute on click in your own listener.

Create your Interface like

InterfaceMyListener{
    publicvoid myClickListener(String content);
}

Now implement this in your MainActivity

publicclassMainActivityextendsActionBarActivityimplementsOnTabChangeListener,ItemSelectedListener,MyListener {
    publicvoidmyClickListener(String content){
        action_bar_hometext.setText(content);
        FragmentManagermanager= getSupportFragmentManager();
        FragmentTransactionft= manager.beginTransaction();
        HomeFirstFragmentnewFragment=newHomeFirstFragment();
        ft.replace(R.id.realtabcontent, newFragment);
        ft.addToBackStack(null);
        ft.commit();
    }
}

Solution 2:

You need to register your MainActivity class in the LayoutActivity class, so that LayoutActivity class can invoke the interface's method.

Add this to your LayoutActivity.java:

privatestaticItemSelectedListener mListener = null;

publicstaticvoidregister(ItemSelectedListener listener){
    mListener = listener;
}

@OverridepublicvoidonClick(View v) {

    switch (v.getId()) {

        case R.id.btn_click:
            if(mListener!=null){
                // ADD THIS LINE
                mListener.onItemSelected(POS/*Your position*/, CONTENT/*Your content*/);
            }

         break;
    }
}

Now, in your MainActivity class, register it to the LayoutActivity class and follows:

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    LayoutActivity.register(this);
}

Hope it helps! :)
