如何在抽屜式導航圖標添加到項目

Question

我想有圖標旁邊，我在我的抽屜式導航欄中的項目，我已經建立了這樣的：

Titles = getResources().getStringArray(R.array.array1); 
    Icons = getResources().getIntArray(R.array.icons); 
    mDrawerLayout = (DrawerLayout)findViewById(R.id.Welcome); 
    mDrawerList = (ListView) findViewById(R.id.left_drawer); 
    mDrawerLayout.setDrawerShadow(R.drawable.drawer_shadow, GravityCompat.START); 
    mDrawerList.setAdapter(new ArrayAdapter<String>(this, R.layout.drawer_list_item, Titles)); 

我知道這個過程必須涉及添加圖像視圖到文本視圖，位於drawer_list_item的XML中，但我不知道該怎麼做。什麼是完成這個最好的方法？

這是我drawer_list_item.xml：

<TextView xmlns:android="http://schemas.android.com/apk/res/android" 
android:id="@android:id/text1" 
android:layout_width="match_parent" 
android:layout_height="wrap_content" 
android:textAppearance="?android:attr/textAppearanceListItemSmall" 
android:gravity="center_vertical" 
android:paddingLeft="16dp" 
android:paddingRight="16dp" 
android:textColor="#111" 
android:background="?android:attr/activatedBackgroundIndicator" 
android:minHeight="?android:attr/listPreferredItemHeightSmall"/> 

Answer 1

抽屜式導航欄基本上是一個列表視圖。用你想要的任何佈局（text + imageview）創建一個drawer_item.xml並將其傳遞給arrayAdapter。然後，當填充listView（在getview方法中）時，將imageView分配給您選擇的drawable。

**R.layout.my drawer_list_item.xml** 

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

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="60dp" > 

    <ImageView 
     android:id="@+id/flag" 
     android:layout_width="40dp" 
     android:layout_height="40dp" 
     android:paddingLeft="10dp" 
     android:paddingTop="10dp" 
     android:paddingRight="10dp" 
     android:paddingBottom="10dp" 
     android:layout_alignParentLeft="true" 
     android:layout_centerVertical="true" 
     android:contentDescription="@string/app_name" /> 

    <TextView 
     android:id="@+id/country" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_toRightOf="@id/flag" 
     android:layout_centerVertical="true" 
     android:textSize="15sp" /> 

    <TextView 
     android:id="@+id/count" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_marginRight="10dp" 
     android:layout_alignParentRight="true" 
     android:layout_centerVertical="true" 
     android:gravity="center" 
     android:padding="0dp" 
     android:background="@color/DarkGray" 
     android:textSize="15sp" /> 

</RelativeLayout> 


**java code** 

private SimpleAdapter mAdapter; 
    private List<HashMap<String,String>> mList ; 
    final private String ITEM = "item"; 
    final private String FLAG = "flag"; 
    final private String COUNT = "count"; 
    String[] mCountries =new String[]{"item 1","item 2","item3"} ; 
    int[] mFlags = new int[]{ 
      R.drawable.abc_ic_clear, 
      R.drawable.abc_ic_clear, 
      R.drawable.abc_ic_clear, 

    }; 
String[] mCount = new String[]{ 
"1", "2", "3" }; 


    @Override 
    public void onCreate(Bundle savedInstanceState) { 
     super.onCreate(savedInstanceState); 


     mList = new ArrayList<HashMap<String,String>>(); 
     for(int i=0;i<3;i++){ 
      HashMap<String, String> hm = new HashMap<String,String>(); 
      hm.put(ITEM, mCountries[i]); 
      hm.put(COUNT, mCount[i]); 
      hm.put(FLAG, Integer.toString(mFlags[i])); 
      mList.add(hm); 
     } 
    } 


**set adapter for ListView** 

@Override 
public View onCreateView(LayoutInflater inflater, ViewGroup container, 
     Bundle savedInstanceState) { 
    mDrawerListView = (ListView) inflater.inflate(
      R.layout.fragment_navigation_drawer, container, false); 
    mDrawerListView.setOnItemClickListener(new AdapterView.OnItemClickListener() { 
     @Override 
     public void onItemClick(AdapterView<?> parent, View view, int position, long id) { 
      selectItem(position); 
     } 
    }); 

    String[] from = { FLAG,ITEM,COUNT }; 


    int[] to = { R.id.flag , R.id.country , R.id.count}; 

    mAdapter = new SimpleAdapter(getActionBar().getThemedContext(), mList, R.layout.my drawer_list_item, from, to); 
    mDrawerListView.setAdapter(mAdapter); 
    mDrawerListView.setItemChecked(mCurrentSelectedPosition, true); 
    return mDrawerListView; 
}
