複選框在CheckedTextView的Android

Question

不顯示我試圖創建一個列表是這樣的：

<image><text>  <checkbox>. 

到目前爲止，文本和圖像顯示，但該複選框沒有。大部分代碼都適合在這裏： http://www.learn2crack.com/2013/10/android-custom-listview-images-text-example.html

activity_filter_restaurants.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:paddingBottom="@dimen/activity_vertical_margin" 
    android:paddingLeft="@dimen/activity_horizontal_margin" 
    android:paddingRight="@dimen/activity_horizontal_margin" 
    android:paddingTop="@dimen/activity_vertical_margin"> 

<ListView 
    android:id="@+id/listFilter"

    android:layout_height="wrap_content"> 
</ListView> 
</RelativeLayout> 

list_filter_restaurants.xml

     LayoutInflater inflater = context.getLayoutInflater(); 
     View rowView= inflater.inflate(R.layout.list_filter_restaurants, null, true); 

     chktxtTitle = (CheckedTextView) rowView.findViewById(R.id.checkedTextView); 

     chktxtTitle.setOnClickListener(new View.OnClickListener(){

       if(chktxtTitle.isChecked()) 
        chktxtTitle.setChecked(false); 
       else

     ImageView imageView = (ImageView) rowView.findViewById(R.id.imgfilter); 
     chktxtTitle.setText(options[position]);

FilterRestaurants.java

     super.onCreate(savedInstanceState); 

     requestWindowFeature(Window.FEATURE_CUSTOM_TITLE); 
     getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.header_food); 

     setContentView(R.layout.activity_filter_restaurants); 

     CustomList adaptor = new CustomList(FilterRestaurants.this,options,optionsId); 

     filterlist = (ListView) findViewById(R.id.listFilter); 
     filterlist.setAdapter(adaptor); 
     // filterlist.setChoiceMode(ListView.CHOICE_MODE_SINGLE); 
     filterlist.setChoiceMode(ListView.CHOICE_MODE_NONE); 
     filterlist.setOnItemClickListener(new AdapterView.OnItemClickListener(){ 
      @Override 
      public void onItemClick(AdapterView<?> parent, View view, int position, long id){ 
       Toast.makeText(FilterRestaurants.this,"Yoy clicked at "+options[+ position],Toast.LENGTH_SHORT).show(); 
      } 
     }); 
    } 

Answer 1

有一個更簡單的實現你正在嘗試做什麼。你可以試試這個。您不需要適配器，可以放開filterlist.java類和list_filter_restaurants.xml文件。只需在您的xml文件中有一個CheckedTextView對象，下面的代碼將在CheckedTextView的左側設置一個圖像。

Drawable imageDrawable = getBaseContext().getResources.getDrawable(R.drawable.your_image_name); 

((CheckedTextView) chktxtTitle).setCompoundDrawables(imageDrawable,null,null,null); 

Answer 2

看你的代碼，我發現以下不一致：

1. getWindow().setFeatureInt(Window.FEATURE_CUSTOM_TITLE, R.layout.header_food);在filterresturants.java應高於setContentView()
2. 裏面你FilterList.java您提供錯誤的佈局資源ID在構造函數的super()和01中方法。將其更改爲R.layout.list_filter_restaurants xml
3. 最後從docs開始，您需要在CheckedTextView內部適配器中將setChoiceMode()設置爲none。
