android gridview适合屏幕大小

Question

我的应用程序的gridview有一个图像和每个网格下面的文本。 我需要确保网格的完整列表适合屏幕（底部没有溢出）。

下面是我定义我的GridView

<GridView xmlns:android="http://schemas.android.com/apk/res/android" 
     android:id="@+id/gridview" android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:numColumns="3" 
     android:stretchMode="columnWidth" 
     android:layout_below="@+id/text1view" 
        android:gravity="center" 
        android:background="@drawable/home_bg" 

           /> 

和每个网格产品：

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:id="@+id/GridItem" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:orientation="vertical" 
    android:gravity="center_horizontal" 
    > 

    <ImageView android:id="@+id/grid_item_image" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:padding="0dip" 
     android:layout_margin="0dip" 
     > 
    </ImageView> 

    <TextView android:id="@+id/grid_item_text" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
      android:textColor="#000000" 
      android:padding="0dip" 
     android:gravity="center_horizontal" 
     android:layout_below="@+id/grid_item_image" 
     android:layout_alignParentBottom="true" 
     > 
    </TextView> 

</LinearLayout> 

我尝试了好几种方法可以设置网格视图布局PARAM，但我没有得到正确的输出。请在这里帮助我。 gridview的适配器代码是

public View getView(final int position, View convertView, ViewGroup parent) { 
    ViewHolder holder; 

    if (convertView == null) { 
     LayoutInflater mInflater = (LayoutInflater) mContext 
       .getSystemService(Context.LAYOUT_INFLATER_SERVICE); 
     convertView = mInflater.inflate(R.layout.griditems, null); 
     holder = new ViewHolder(); 
     holder.text1 = (TextView) convertView 
       .findViewById(R.id.grid_item_text); 
     Log.i(TAG, holder.text1.toString()); 
     holder.image = (ImageView) convertView 
       .findViewById(R.id.grid_item_image); 

     // if it's not recycled, initialize some attributes 
     holder.image.setImageResource(gridItemIds[position]); 
     holder.text1.setText(gridTitles[position]); 
     int h = mContext.getResources().getDisplayMetrics().densityDpi; 
     convertView.setLayoutParams(new GridView.LayoutParams(h-50, h-20)); 
     //holder.image.setScaleType(ImageView.ScaleType.CENTER_CROP); 
     //holder.image.setScaleType(ImageView.ScaleType.FIT_XY); ...... 

Answer 1

尝试

android:layout_width="fill_parent" 
android:layout_height="fill_parent" 

为你的GridView，而不是WRAP_CONTENT！

Answer 2

试试这个： -

grid_item.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout 
    xmlns:android="http://schemas.android.com/apk/res/android" 
    android:orientation="vertical" 
    android:layout_width="match_parent" 
android:layout_height="match_parent"> 
<LinearLayout android:id="@+id/linearLayout1" android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:gravity="center"> 
<ImageView android:id="@+id/imgIcon" android:src="@drawable/icon" android:layout_width="wrap_content" android:layout_height="wrap_content"></ImageView> 
<TextView android:text="TextView" android:id="@+id/txtDesc" android:layout_height="wrap_content" android:layout_width="wrap_content"></TextView> 
</LinearLayout> 
</LinearLayout> 

gridview.xml

<?xml version="1.0" encoding="utf-8"?> 
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" 
android:orientation="vertical" 
android:layout_width="fill_parent" 
android:layout_height="fill_parent" 
> 
<GridView xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/mobGrid" 
android:layout_width="match_parent" 
android:layout_height="match_parent" 
android:padding="10dp" 
android:verticalSpacing="10dp" 
android:horizontalSpacing="10dp" 
android:numColumns="auto_fit" 
android:columnWidth="60dp" 
android:stretchMode="columnWidth" 
android:gravity="center" 
/> 
</LinearLayout>
