如何使用导航抽屉上的项目打开其他活动

Question

I am creating a guide app, and I want other users to tap on an item on the navigation drawer, how can I make it open another activity? This is the MainApplication.java:

 package net.agiann.paliachora_guide;

import android.app.Application;
import android.test.ApplicationTestCase;

    /**
     * <a href="http://d.android.com/tools/testing/testing_android.html">Testing Fundamentals</a>
     */
    public class ApplicationTest extends ApplicationTestCase<Application> {
        public ApplicationTest() {
            super(Application.class);
        }
    }

Answer 1

 navigationView.setNavigationItemSelectedListener(new NavigationView.OnNavigationItemSelectedListener() {

            // This method will trigger on item Click of navigation menu
            @Override
            public boolean onNavigationItemSelected(MenuItem menuItem) {


                //Checking if the item is in checked state or not, if not make it in checked state
                if (menuItem.isChecked()) menuItem.setChecked(false);
                else menuItem.setChecked(true);

                //Closing drawer on item click
                drawerLayout.closeDrawers();

                //Check to see which item was being clicked and perform appropriate action
                switch (menuItem.getItemId()) {


                    //Replacing the main content with ContentFragment Which is our Inbox View;
                    case R.id.drawer_home:

                        Intent intent=new Intent(HomeActivity.this, HomeActivity.class);
                        startActivity(intent);

                        finish();
                        return true;

                    // For rest of the options we just show a toast on click


                    default:
                        Toast.makeText(getApplicationContext(), "Somethings Wrong", Toast.LENGTH_SHORT).show();
                        return true;

                }
            }
        });

try this:

implement your activity NavigationView.OnNavigationItemSelectedListener

public boolean onNavigationItemSelected(MenuItem item) {
    // Handle navigation view item clicks here.
    int resultCode = GooglePlayServicesUtil
            .isGooglePlayServicesAvailable(this);
    int id = item.getItemId();

    if (id == R.id.nav_home) {
        Intent intent=new Intent(this,HomeActivity.class);
        startActivity(intent);
    }else if(second codition){

    }

    DrawerLayout drawer = (DrawerLayout) findViewById(R.id.drawer_layout);
    drawer.closeDrawer(GravityCompat.START);
    return true;
}

            @Override
            public boolean onNavigationItemSelected(MenuItem menuItem) {

                switch (menuItem.getItemId()) {
                    case R.id.nav_item_Animation:
                      Intent intent=new Intent(this,MainActivity.class);
    startActivity(intent);
                        break;
                    case R.id.nav_item_loginScreen:
                       Intent intent=new Intent(this,LoginActivity.class);
    startActivity(intent);
                        break;
}
                return false;
});
