通过导航抽屉在活动之间切换

Question

I have 2 activities which extend a base activity:

Class BaseActivity extends Activity
Class A extends BaseActivity
Class B extends BaseActivity

Now I have a button on A which allows the user to go to B , and a button on B which allows to go back to A .

So far, so good.
Now after reading this documentation, which is straightforward enough, I am implementing an additional activity between BaseActivity and A , B . The structure will be:

Class BaseActivity extends Activity
Class MyDrawer extends BaseActivity
Class A extends MyDrawer
Class B extends MyDrawer

The activity MyDrawer contains the code to use a Navigation Drawer. The problem I have is, I am not able to understand how do I use my Activities instead of Fragments in the Navigation Drawer. I want the users to be able to switch between activities through the drawer. Is this possible? or do I need to rewrite everything using Fragments instead of Activities?

Any help is appreciated.

Answer 1

Use intent's to switch between the activities. Refer to Navigation Drawer to switch between activities

public void selectItem(int position) {
Intent intent = null;
switch(position) {
    case 0:
        intent = new Intent(this, Activity_0.class);
        break;
    case 1:
        intent = new Intent(this, Activity_1.class);
        break;

    ...


    case 4: 
        intent = new Intent(this, Activity_4.class);
        break;

    default : 
        intent = new Intent(this, Activity_0.class); // Activity_0 as default
        break;
}

startActivity(intent);

}
