Android 所有活动中的导航抽屉

我正在使用导航抽屉的导航视图…抽屉中有某些菜单项，当我单击某个特定活动时，会打开一个新活动，我也想从该活动中打开导航抽屉。。我尝试了一种方法，将我的主要活动（具有抽屉的活动）扩展到活动（或第二个活动）…并将其添加到第二个活动中，而不是setcontentview。。但问题是我的第二个活动xml就在mainactivity.xml之上。。我看到了两个活动（mainactivity.xml上方的secondactivity）如何仅显示抽屉中的secondactivity

LayoutInflater layoutInflater = (LayoutInflater)getSystemService(Context.LAYOUT_INFLATER_SERVICE);
        View activityView = layoutInflater.inflate(R.layout.activity_credits, null,false);
        // add the custom layout of this activity to frame layout.
        drawerLayout.addView(activityView);

您可以通过创建一个公共类BaseActivity.java来完成此任务，并将导航抽屉的代码放在这个类中。并使用BaseActivity.java扩展类，在其中显示导航抽屉

public class BaseActivity extends AppCompatActivity  {

    public Toolbar toolbar;                              // Declaring the Toolbar Object

    protected boolean useToolbar() {
        return true;
    }


    @Override

        DrawerLayout fullView = (DrawerLayout) getLayoutInflater().inflate(R.layout.drawer_main, null);
        FrameLayout activityContainer = (FrameLayout) fullView.findViewById(R.id.frame);
        getLayoutInflater().inflate(layoutResID, activityContainer, true);

        super.setContentView(fullView);
        toolbar = (Toolbar) fullView.findViewById(R.id.tool_bar);

        setSupportActionBar(toolbar);
        getSupportActionBar().setTitle("");
        toolbar.setTitle("");
        this.getSupportActionBar().setElevation(0);

        getSupportActionBar().setLogo(R.drawable.ic_arrahm);
        //  toolbar.setLogo(R.drawable.ic_main);
        if (useToolbar()) {
            setSupportActionBar(toolbar);

                switch (menuItem.getItemId()) {
                    case R.id.edit_profile:                   
                        return true;
                    case R.id.change_password:
                        return true;
                    default:
                        Toast.makeText(getApplicationContext(), "Work in progress", Toast.LENGTH_SHORT).show();
                        return true;
                }
            }
        });

        // Initializing Drawer Layout and ActionBarToggle
        drawerLayout = (DrawerLayout) findViewById(R.id.drawerLayout);
        View header = navigationView.getHeaderView(0);
        TextView tvName = (TextView) header.findViewById(R.id.name);
        TextView tvEmail = (TextView) header.findViewById(R.id.email);
        String name = Preferences.getDataFromStringPreferences(context,Constants.USER_DETAILS, Constants.USER_NAME);

        if (name != null) {
            tvName.setText(name);
        }


        ActionBarDrawerToggle actionBarDrawerToggle = new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.openDrawer, R.string.closeDrawer) {

            @Override
            public void onDrawerClosed(View drawerView) {
                // Code here will be triggered once the drawer closes as we dont want anything to happen so we leave this blank
                super.onDrawerClosed(drawerView);

    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        return mDrawerToggle.onOptionsItemSelected(item);
