以编程方式设置gridview列宽度不起作用

I was having some problem when trying to set the grid view column width programmatically. My grid view has two columns and I wanted to set the column width specifically instead of the equal size. Here is my .xml file:

尝试以编程方式设置网格视图列宽时出现问题。我的网格视图有两列，我想专门设置列宽而不是相等的大小。这是我的.xml文件：

<GridView
    android:id="@+id/gridView"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:numColumns="2"
/>

And my code to check for the position to set the width programmatically:

我的代码检查以编程方式设置宽度的位置：

 adapter = new ArrayAdapter<String>(this.getContext(), android.R.layout.simple_list_item_1, items) {
        @Override
        public View getView(int position, View convertView, ViewGroup parent) {
            TextView cell = (TextView) super.getView(position, convertView, parent);

            if (position % 2 == 0) {
                cell.setLayoutParams(new LinearLayout.LayoutParams(200, LinearLayout.LayoutParams.WRAP_CONTENT, (float) 0.2));
            } else {
                cell.setLayoutParams(new LinearLayout.LayoutParams(700, LinearLayout.LayoutParams.WRAP_CONTENT, (float) 0.7));
            }
            return cell;
        }

However, it becomes like this. The second column does not expand to fit the full width although I already set the width to 700.

但是，它变成了这样。虽然我已经将宽度设置为700，但第二列不会扩展以适应整个宽度。

Any ideas? Thanks in advanced!

有任何想法吗？先谢谢了！

Try to used Recyclerview it only add one line you can make one or more column in equal size..

尝试使用Recyclerview它只添加一行，你可以制作一个或多个相同大小的列。

  /**
 * this method initialized view control.
 */
private void initView() {
    mRvData = findViewById(R.id.amRvData);


    // below code set layout and scrolling in vertical
   // mRvData.setLayoutManager(new LinearLayoutManager(this));

    // if you want to scroll as horizontal way used below code.
    // mRvData.setLayoutManager(new LinearLayoutManager(this,LinearLayoutManager.HORIZONTAL,false));

    // if you want to show grid layout used below code
     mRvData.setLayoutManager(new GridLayoutManager(this,2,LinearLayoutManager.VERTICAL,false));

    mRvData.setItemAnimator(new DefaultItemAnimator());
    mRvData.addItemDecoration(new DividerItemDecoration(this, LinearLayoutManager.VERTICAL));

}
