Android的列表視圖多列有一個複選框

現在我的代碼使用R.佈局。 simple_list_item_multiple_choice，它的工作完美的罰款。因爲我還需要第二TextView的，我試圖創建具有2的TextView和1個複選框我自己的XML。Android的列表視圖多列有一個複選框

我需要在我的列表視圖2動作：OnClickListener將打開一個新的活動，OnLongClickLisener將檢查/取消選中。

這是問題所在，如果我添加一個複選框，我失去了點擊我的ListView的能力，我只能點擊複選框。

這裏是我的代碼一個簡單的版本：（現在我還沒有改變的Checkmark代碼，因爲我不能讓它與我的新3列版本工作）

Main2Acitvity：

if (POSITION == 1){ 

     setContentView(R.layout.activity_main2); 
     Log.d(TAG, "onCreate: Started."); 
     mActionBarToolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(mActionBarToolbar); 
     getSupportActionBar().setTitle("Stigmate"); 

     ImageView = (ImageView)findViewById(R.id.imageView2); 
     ImageView.setImageResource(R.drawable.r_stigmate); 
     listView = (ListView)findViewById(R.id.listView); 

     Person john = new Person("Première cicatrice","V.0"); 
     Person john1 = new Person("Première cicatrice","V.0"); 
     Person john2= new Person("Première cicatrice","V.0"); 
     Person john3 = new Person("Première cicatrice","V.0"); 

     ArrayList<Person> peopleList = new ArrayList<>(); 
     peopleList.add(john); 
     peopleList.add(john1); 
     peopleList.add(john2); 
     peopleList.add(john3); 

     PersonListAdapter adapter = new PersonListAdapter(this, R.layout.adapter_view_layout, peopleList);

這裏的問題是，如果我添加一個複選框，我失去了點擊對我的能力ListView和我只可以點擊複選框。

添加android:descendantFocusability="blocksDescendants"到RelativeLayout的你activity_main2.xml的

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     ..... 
    android:descendantFocusability="blocksDescendants 
    tools:context="com.carte.alex.test3.MainActivity">

在複選框元素添加android:focusable="false"。
