Question

我有一个像这样的2列列表布局：

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

<LinearLayout
     xmlns:android="http://schemas.android.com/apk/res/android"
     android:paddingTop="4dip"
     android:paddingBottom="6dip"
     android:layout_marginLeft="10dp"     
     android:layout_width="fill_parent"

     android:layout_height="wrap_content"
     android:orientation="horizontal">

     <TextView android:id="@+id/TRAIN_CELL"
         android:layout_width="275dip"
         android:layout_height="wrap_content"
         android:textSize="16sp"/>

     <TextView android:id="@+id/TO_CELL"
         android:layout_width="25dip"
         android:textSize="20sp"
         android:textStyle="bold" 
         android:gravity="center"
         android:textColor="@color/light_best_blue"
         android:layout_height="wrap_content"  
         android:layout_weight="1"/>

</LinearLayout>

但是行：android：layout_marginLeft =“10dp”不会产生和添加空间的效果。此外，屏幕本身有左边距，但列表也没有响应。

有没有办法确保屏幕左侧有间距？

谢谢！

以下是代码：

private List<HashMap<String, String>> fillMaps;
private SimpleAdapter adapter;

ListView list = null;

    list = (ListView) findViewById(android.R.id.list);

    // My data
    fillMaps = new ArrayList<HashMap<String, String>>();

    adapter = new SimpleAdapter(this, fillMaps, R.layout.questions_list,
            new String[] {"train", "to"}, 
            new int[] {R.id.TRAIN_CELL,  R.id.TO_CELL});        
    //adapter = new ArrayAdapter<Question>(this, R.layout.user_question_list, questions);

    setListAdapter ( adapter );

    ListView lv = getListView();
    lv.setTextFilterEnabled(true);

后来我填充了这个列表：

                            HashMap<String, String> map = new HashMap<String, String>();                                
                            JSONObject o = obj.getJSONObject(i);

                            String question_id = o.getString("question_id");
                            String question = o.getString("question");
                            String questioner_id = o.getString("member_id");
                            String first_name = o.getString("first_name");
                            String last_name = o.getString("last_name");

                            Question q = new Question ( );
                            q.setQuestion(question);
                            q.setQuestionId(question_id);
                            q.setQuestionByMemberId( questioner_id );

                            q.setAuthorName(first_name + " " + last_name );

                            map.put("train", question);

                            //map.put("from", ">");
                            map.put("to", ">");

                            fillMaps.add(map);
                            questions.add( q );

尝试更改

 android:layout_marginLeft="10dp"

到

 android:layout_paddingLeft="10dp"

Android - 如何在2列布局的左侧添加间距？
