如何實現從右側

Question

我已經創建了打開的抽屜菜單中創建以下this tutorial

一個導航抽屜但我需要的是，我需要從右側打開同一個抽屜菜單。任何人都知道如何做到這一點？

以下是我的XML

<android.support.v4.widget.DrawerLayout xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools" 
xmlns:app="http://schemas.android.com/apk/res-auto" 
android:id="@+id/drawer" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:fitsSystemWindows="true" 
tools:context=".MainActivity"> 

<LinearLayout 
    android:layout_height="match_parent" 
    android:layout_width="match_parent" 
    android:orientation="vertical" 
    > 
    <include 
     android:id="@+id/toolbar" 
     layout="@layout/tool_bar" 
    /> 
    <FrameLayout 
     android:id="@+id/frame" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent"> 

    </FrameLayout> 

</LinearLayout> 
<android.support.design.widget.NavigationView 
    android:id="@+id/navigation_view" 
    android:layout_height="match_parent" 
    android:layout_width="wrap_content" 
    android:layout_gravity="right" 
    app:headerLayout="@layout/header" 
    app:menu="@menu/drawer" 
    /> 

和代碼

// Initializing Drawer Layout and ActionBarToggle 
    drawerLayout = (DrawerLayout) findViewById(R.id.drawer); 
    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); 
     } 

     @Override 
     public boolean onOptionsItemSelected(MenuItem item) { 
      if (item != null && item.getItemId() == android.R.id.home) { 
       if (drawerLayout.isDrawerOpen(Gravity.RIGHT)) { 
        drawerLayout.closeDrawer(Gravity.RIGHT); 
       } else { 
        drawerLayout.openDrawer(Gravity.RIGHT); 
       } 
      } 
      return false; 
     } 

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

      super.onDrawerOpened(drawerView); 
     } 

    }; 

Answer 1

代替android:layout_gravity="start"

<android.support.design.widget.NavigationView 
     android:id="@+id/navigation_view" 
     android:layout_height="match_parent" 
     android:layout_width="wrap_content" 
     android:layout_gravity="end" 
     app:headerLayout="@layout/header" 
     app:menu="@menu/drawer" 
     /> 

在Java活動文件//添加這些行試試這個在您的導航視圖

android:layout_gravity="end"，它會工作

@Override 
    public boolean onOptionsItemSelected(MenuItem item) { 

     switch (item.getItemId()) { 
      case android.R.id.home: 
       if (mDrawer.isDrawerOpen(Gravity.RIGHT)) { 
        mDrawer.closeDrawer(Gravity.RIGHT); 
       } else { 
        mDrawer.openDrawer(Gravity.RIGHT); 
       } 
       return true; 
      case R.id.action_settings: 
       return true; 
     } 

最後更新：

我改變了一些行您的示例項目（MainActivity.java），現在它正在工作，使用此代碼。

不要忘記在你的xml文件中寫android:layout_gravity="end"來代替android:layout_gravity="start"。

package com.android4dev.navigationview; 


import android.support.design.widget.NavigationView; 
import android.support.v4.widget.DrawerLayout; 
import android.support.v7.app.ActionBar; 
import android.support.v7.app.ActionBarDrawerToggle; 
import android.support.v7.app.AppCompatActivity; 
import android.os.Bundle; 
import android.support.v7.widget.Toolbar; 
import android.view.Gravity; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.widget.Toast; 


public class MainActivity extends AppCompatActivity { 

    Toolbar toolbar; 
    NavigationView navigationView; 
    DrawerLayout drawerLayout; 

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

     toolbar=(Toolbar)findViewById(R.id.toolbar); 
     navigationView=(NavigationView)findViewById(R.id.navigation_view); 
     drawerLayout=(DrawerLayout)findViewById(R.id.drawer); 


     // Set a Toolbar to replace the ActionBar. 
     setToolbarAsActionBar(); 
     // Setup drawer view 
     setupDrawerContent(navigationView); 

     // Set the menu icon instead of the launcher icon. 
     final ActionBar ab = getSupportActionBar(); 
     ab.setHomeAsUpIndicator(R.drawable.ic_menu); 
     ab.setDisplayHomeAsUpEnabled(true); 
     //ab.setDisplayShowTitleEnabled(false); 

     Menu menu = navigationView.getMenu(); 
     MenuItem item = menu.findItem(R.id.starred); 
     selectDrawerItem(item); 

    } 

    private void setToolbarAsActionBar() { 
     setSupportActionBar(toolbar); 
    } 

    @Override 
    public boolean onCreateOptionsMenu(Menu menu) { 
     getMenuInflater().inflate(R.menu.menu_main, menu); 
     return true; 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 

     switch (item.getItemId()) { 
      case android.R.id.home: 
       if (drawerLayout.isDrawerOpen(Gravity.RIGHT)) { 
        drawerLayout.closeDrawer(Gravity.RIGHT); 
       } else { 
        drawerLayout.openDrawer(Gravity.RIGHT); 
       } 
       return true; 
      case R.id.action_settings: 
       return true; 
     } 
     return super.onOptionsItemSelected(item); 
    } 

    private void setupDrawerContent(NavigationView navigationView) { 

     navigationView.setNavigationItemSelectedListener(
       new NavigationView.OnNavigationItemSelectedListener() { 
        @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); 

         selectDrawerItem(menuItem); 
         return true; 
        } 
       }); 
    } 

    public void selectDrawerItem(MenuItem menuItem) { 
     // Create a new fragment and specify the planet to show based on 
     // position 

     switch (menuItem.getItemId()) { 

      case R.id.inbox: 
       Toast.makeText(getApplicationContext(), "Inbox Selected", Toast.LENGTH_SHORT).show(); 
       ContentFragment fragment = new ContentFragment(); 
       android.support.v4.app.FragmentTransaction fragmentTransaction = getSupportFragmentManager().beginTransaction(); 
       fragmentTransaction.replace(R.id.frame, fragment); 
       fragmentTransaction.commit(); 
       break; 

      case R.id.starred: 
       Toast.makeText(getApplicationContext(), "Stared Selected", Toast.LENGTH_SHORT).show(); 
       break; 

      case R.id.sent_mail: 
       Toast.makeText(getApplicationContext(), "Send Selected", Toast.LENGTH_SHORT).show(); 
       break; 

      case R.id.drafts: 
       Toast.makeText(getApplicationContext(), "Drafts Selected", Toast.LENGTH_SHORT).show(); 
       break; 

      case R.id.allmail: 
       Toast.makeText(getApplicationContext(), "All Mail Selected", Toast.LENGTH_SHORT).show(); 
       break; 

      case R.id.trash: 
       Toast.makeText(getApplicationContext(), "Trash Selected", Toast.LENGTH_SHORT).show(); 
       break; 

      case R.id.spam: 
       Toast.makeText(getApplicationContext(), "Spam Selected", Toast.LENGTH_SHORT).show(); 
       break; 

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

     } 

     drawerLayout.closeDrawers(); 
    } 

    private ActionBarDrawerToggle setupDrawerToggle() { 
     return new ActionBarDrawerToggle(this, drawerLayout, toolbar, R.string.openDrawer, R.string.closeDrawer); 
    } 

} 

Answer 2

這是可能的。您必須在導航抽屜設置android:layout_gravity="right"，改變它的嚴重性：

mDrawerToggle = new ActionBarDrawerToggle(this, mDrawerLayout, 
      R.drawable.ic_drawer, R.string.drawer_open, 
      R.string.drawer_close) { 

     @Override 
     public boolean onOptionsItemSelected(MenuItem item) { 
      if (item != null && item.getItemId() == android.R.id.home) { 
       if (mDrawerLayout.isDrawerOpen(Gravity.RIGHT)) { 
        mDrawerLayout.closeDrawer(Gravity.RIGHT); 
       } else { 
        mDrawerLayout.openDrawer(Gravity.RIGHT); 
       } 
      } 
      return false; 
     } 
    }; 

這應該工作！
