Listenansicht innerhalb der Liste Anzeigen in android

Question

Ich benutze eine Listenansicht in einem Listenansicht, und beide Listenansicht teilen denselben Listeneintrag. Es funktioniert gut, aber wenn die Höhe des Artikels in der Listenansicht erhöht wird, wird der Inhalt nicht umgebrochen und ein Scrollview eingefügt, der nicht der Anforderung entspricht. Bitte beachten Sie die folgenden Codes

activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="match_parent" 
    android:layout_height="match_parent" 
    android:background="#ffffff" 
    android:orientation="vertical"> 

    <ListView 
     android:id="@+id/list_comments" 
     android:layout_width="match_parent" 
     android:layout_height="match_parent" 
     android:layout_marginLeft="10dp" 
     android:layout_marginRight="10dp" 
     android:layout_marginTop="10dp" 
     android:divider="@android:color/transparent" 
     android:dividerHeight="5dp" />

bitte auf den markierten Bereich der Bildlistenansicht Höhe sehen, ist nicht der eigentliche Inhalt

jede Hilfe zu wickeln

Answer 1

Das Problem ist, dass Sie die Rolle nicht von beiden Listenansicht zu einem Zeitpunkt, bekommen. wenn du was du beide gleichzeitig machst. Sie müssen eine benutzerdefinierte Listenansicht erstellen, indem Sie etwas Ähnliches anstelle Ihrer Listenansicht (in der Liste) versuchen.

public class NonScrollListView extends ListView { 
    public NonScrollListView(Context context) { 
     super(context); 
    } 

    public NonScrollListView(Context context, AttributeSet attrs) { 
     super(context, attrs); 
    } 

    public NonScrollListView(Context context, AttributeSet attrs, int defStyle) { 
     super(context, attrs, defStyle); 
    } 

    @Override 
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { 
     int heightMeasureSpec_custom = MeasureSpec.makeMeasureSpec(
       Integer.MAX_VALUE >> 2, MeasureSpec.AT_MOST); 
     super.onMeasure(widthMeasureSpec, heightMeasureSpec_custom); 
     ViewGroup.LayoutParams params = getLayoutParams(); 
     params.height = getMeasuredHeight(); 
    } 
} 

Answer 2

Ihr sind einige Punkte, die Sie beheben müssen appericiated würde zu .

• eine richtige Höhe so zu Ihrem ListView Gib, dass es innerhalb dieser boundry bewegen kann, wird wrap_content nie für ListView empfohlen. Also besser, um etwas Höhe zu Ihrem ListView zu setzen.

• Listview innerhalb einer ListView wird nicht die Benutzererfahrung gut geben. Versuchen Sie eine Arbeit oder besser zu verwenden RecyclerView. RecyclerView ist im Falle einer verschachtelten Liste besser in der Leistung.

Hoffe, es hilft :)
