使用導航抽屜更改佈局

當我在Android Studio中啓動一個新的「導航抽屜」項目時，已經有一些代碼。如何通過使用抽屜中的按鈕來更改佈局？使用導航抽屜更改佈局

抽屜式導航欄看起來像這樣

期待您的MainActivity XML，你會發現結構如下喜歡：

<android.support.v4.widget.DrawerLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
xmlns:tools="http://schemas.android.com/tools 
android:id="@+id/drawer_layout" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
tools:context=".MainActivity"> 

<FrameLayout android:id="@+id/container" 
android:layout_width="match_parent" 
android:layout_height="match_parent" /> 

<!-- you can custom your layout here in LinearLayout--> 
<LinearLayout android:id="@+id/navigation_drawer" 
android:layout_width="240dp" 
android:layout_height="match_parent" 
android:layout_gravity="start" 
tools:layout="@layout/fragment_navigation_drawer" > 

<!-- you can add a button here--> 
<Button 
    android:id="@+id/Button1" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:text="mButton"/> 

</LinearLayout> 
</android.support.v4.widget.DrawerLayout>

，你可以定製你的片段視圖，或者不是用此處爲一個Linearlayout，並在佈局中填充按鈕。

mLinearLayout = (LinearLayout) findViewById(R.id.navigation_drawer); 
mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout); 

mButton = (DrawerLayout) findViewById(R.id.Button1); 
mButton.setOnClickListener(new OnClickListener() { 

     @Override 
     public void onClick(View arg0) { 
      // TODO Auto-generated method stub 
      //close DrawerLayout here 
      mDrawerLayout.closeDrawer(mLinearLayout); 
     } 
    });

您可以使用一個片段取代的FrameLayout：

FragmentTransaction fragmentTransaction1 = fragmentManager 
        .beginTransaction(); 
      fragmentTransaction1.replace(R.id.content_frame, 
        overviewFragment); 
      fragmentTransaction1.commit();

你能給我一些代碼，我怎麼可以從例如去佈局1到佈局2通過抽取導航抽屜並按例如。按鈕圖庫？ – Validor

在你的Activy中，設置onclickListener on Button和mDrawerLayout.closeDrawer（mLinearLayout）; – fozua

試試這個代碼：

我們不應該用碎片處理每個佈局嗎？爲了照顧每個佈局可能需要的所有後臺工作？ – Cedric
