Android DrawerLayout在點擊圖標時崩潰

Question

所以我想了解DrawerLayout。首先，我創建了它，並且它運行良好。然後我嘗試通過添加左上角的圖標來操作它，這樣可以顯示/隱藏列表。 問題是，當我啓動應用程序時，列表已顯示，當我試圖通過單擊圖標來隱藏它時，應用程序崩潰。下面是我的文件： activity_main.xml中：

<android.support.v4.widget.DrawerLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/DrawerLayout1" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent"> 

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

     <ListView 
      android:id="@+id/ListView1" 
      android:layout_width="241dp" 
      android:layout_height="match_parent" 
      android:layout_gravity="start" 
      android:choiceMode="singleChoice" 
      android:divider="#666" 
      android:dividerHeight="1dp" 
      android:background="#333" 
      android:paddingLeft="15sp" 
      android:paddingRight="15sp"/> 
    </FrameLayout> 


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

Item_Layout：（佈局在列表中的項目（各一個））：

<?xml version="1.0" encoding="utf-8"?> 

<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/Element" 
     android:layout_width="match_parent" 
     android:layout_height="wrap_content" 
     android:textColor="#fff" 
     android:textSize="20sp" 
     android:gravity="center_vertical" 
     android:paddingStart="14.5sp" 
     android:paddingEnd="14.5sp" 
     android:minHeight="35sp"/> 

MainActivity.java：

package com.example.drawerlisttest; 

import android.app.Activity; 
import android.content.res.Configuration; 
import android.os.Bundle; 
import android.support.v4.app.ActionBarDrawerToggle; 
import android.support.v4.view.GravityCompat; 
import android.support.v4.widget.DrawerLayout; 
import android.view.Menu; 
import android.view.MenuItem; 
import android.widget.ArrayAdapter; 
import android.widget.ListView; 

public class MainActivity extends Activity { 

    String[] ListElement; 
    ListView List; 
    DrawerLayout DLayout; 
    ActionBarDrawerToggle ABDT; 

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

     ListElement = getResources().getStringArray(R.array.StringList); 
     List = (ListView)findViewById(R.id.ListView1); 
     List.setAdapter(new ArrayAdapter<String>(this, R.layout.item_layout, ListElement)); 

     //Set the Icon: 
     DLayout = (DrawerLayout)findViewById(R.id.DrawerLayout1); 
     ABDT = new ActionBarDrawerToggle(this, DLayout, R.drawable.ic_drawer, R.string.drawer_open, R.string.drawer_close); 

     //Faire de l'actionBarDrawerToggle un DrawerListener de DrawerLayout 
     DLayout.setDrawerListener(ABDT); 
     getActionBar().setDisplayHomeAsUpEnabled(true); 

     //Add the shodow to the right after displying the list 
     DLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); 
    } 

    @Override 
    public void onConfigurationChanged(Configuration newConfig){ 
     super.onConfigurationChanged(newConfig); 
     ABDT.onConfigurationChanged(newConfig); 
    } 

    @Override 
     public boolean onOptionsItemSelected(MenuItem item) { 

      // call ActionBarDrawerToggle.onOptionsItemSelected(), if it returns true 
      // then it has handled the app icon touch event 
      if (ABDT.onOptionsItemSelected(item)) { 
       return true; 
      } 
      return super.onOptionsItemSelected(item); 
     } 
}

正如你所看到的，日誌說了一些關於重力的東西，我在佈局文件中查找它，並且沒有這樣的節點，但是沒有重力=左或類似的東西...

至於string.xml，好;我不認爲這是必要的重要...

謝謝。

嘗試從您的FrameLayout中刪除您的listView。

<android.support.v4.widget.DrawerLayout 
xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@+id/DrawerLayout1" 
android:layout_width="match_parent" 
android:layout_height="match_parent"> 

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

<ListView 
    android:id="@+id/ListView1" 
    android:layout_width="241dp" 
    android:layout_height="match_parent" 
    android:layout_gravity="start" 
    android:choiceMode="singleChoice" 
    android:divider="#666" 
    android:dividerHeight="1dp" 
    android:background="#333" 
    android:paddingLeft="15sp" 
    android:paddingRight="15sp"/> 

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