ScrollView下 GridView 顯示不完全

重寫GridView

public class HFGridView extends GridView {
    public HFGridView(Context context) {
        super(context);
    }
    public HFGridView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }
    public HFGridView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }
    @Override
    public void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        int expandSpec = MeasureSpec.makeMeasureSpec(Integer.MAX_VALUE >> 2,MeasureSpec.AT_MOST);
        super.onMeasure(widthMeasureSpec, expandSpec);
    }
}

Layout使用

    <YourPackageName.HFGridView
        android:id="@+id/gv_use"
        style="@style/search_grid_view"
        android:numColumns="4" />

程式內宣告使用

HFGridView gv = (HFGridView) findViewById(R.id.gv_use);
gv.setOnItemClickListener(new GridView.OnItemClickListener() {
    @Override
    public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
             //do something
    }
});
