화면 중앙에 거치 뷰를 중앙에 배치하는 방법은 무엇입니까?

Question

화면 중간에 gridview를 가운데에 배치하는 데 문제가 있습니다. 오른쪽 하단은 왼쪽보다 더 많은 여백이 있습니다. gridview를 상대적인 위치에 놓고 중심에 두는 것을 포함하여 모든 것을 시도했습니다.

activity_main.xml 문제의

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
       xmlns:tools="http://schemas.android.com/tools" 
       android:layout_width="match_parent" 
       android:layout_height="90dp" 
       android:gravity="center" 
       android:orientation="vertical" 
       android:minHeight="90dp" 
       android:padding="16dp" 
       android:background="#EEEEEE"> 



     <TextView 
      android:id="@+id/text_1" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      tools:text="test text" 
      android:maxLines="2" 
      /> 


</LinearLayout>

grid_item.xml : 오른쪽에 빈 공간을 많이가 볼 수 있습니다. enter image description here

RelativeLayout의 아이 뷰 안드로이드 : layout_centerInParent는 = "true"를

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" android:layout_width="match_parent" 
    android:layout_height="90dp"> 
    <TextView 
     android:id="@+id/text_1" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerInParent="true" 
     android:text="text" 
     android:maxLines="2" 
     /> 

</RelativeLayout> 

Answer 3

If you want to keep same space then you have to set dynamic property of gridview like this. 

    /** 
    * Set gridView data according to device width. 
    */ 
    private void InitilizeGridLayout() { 
     Resources r = getResources(); 
     float padding = TypedValue.applyDimension(TypedValue.COMPLEX_UNIT_DIP, 2, r.getDisplayMetrics()); 

     columnWidth = (int) ((getScreenWidth() - ((3 + 1) * padding))/3); 

     gvGallery.setNumColumns(3); 
     gvGallery.setColumnWidth(columnWidth); 
     gvGallery.setStretchMode(GridView.NO_STRETCH); 
     gvGallery.setPadding((int) padding, (int) padding, (int) padding, (int) padding); 
     gvGallery.setHorizontalSpacing((int) padding); 
     gvGallery.setVerticalSpacing((int) padding); 
    }

당신이 RelativeLayout의 내부의 GridView를 넣어 그냥 true로의 GridView의 layout_centerInParent을 설정하기 위해 필요한이 방법을 시도 사용 ..

<?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="match_parent"> 

    <GridView 
      android:id="@+id/grid" 
      android:layout_width="match_parent" 
      android:layout_height="match_parent" 
      android:numColumns="7" 
      android:columnWidth="40dp" 
      android:verticalSpacing="1dp" 
      android:horizontalSpacing="1dp" 
      android:paddingTop="2dp" 
      android:stretchMode="columnWidth" 
      android:background="#696969" 
      android:layout_centerInParent="true" /> 

</RelativeLayout>
