ナビゲーションドロワーのアイテムを使用して他のアクティビティを開く方法

Question

ガイドアプリを作成していて、他のユーザーがナビゲーションドロワーのアイテムをタップするようにするには、どうすれば別のアクティビティを開くことができますか？ これはMainApplication.javaです：

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; 

       } 
      } 
     }); 

Answer 2

これを試してみてください。

あなたが、ここではテストスイートを掲載しませ

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) { 
       mDrawerLayout.closeDrawers(); 
       switch (menuItem.getItemId()) { 
        case R.id.nav_item_Animation: 
         Intent intent=new Intent(this,MainActivity.class); 
    startActivity(intent); 
         break;

         Intent intent=new Intent(this,LoginActivity.class); 
    startActivity(intent); 
         break; 
} 
       return false;
