android - 如何让customAdapter填充gridview高度

Question

我正在开发数独应用程序。布局为 9x9 GridView。每个 GridView 包含 9 个由 customAdapter 提供的 Textview。我想让 9 个 TextView 填充每个 GridView 的高度。怎么办？

这就是我现在拥有的

这是 myGridAdapter:

public class myGridAdapter extends BaseAdapter {

private Context context;
private String[] mobileValues;

public myGridAdapter(MainActivity mainActivity, String[] arrayEmpty) {
    this.context = mainActivity;
    this.mobileValues = arrayEmpty;
}

public View getView(int position, View convertView, ViewGroup parent) {

    LayoutInflater inflater = (LayoutInflater) context
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

    View gridView;

    if (convertView == null) {

        gridView = new View(context);

        // get layout from text_item.xml
        gridView = inflater.inflate(R.layout.text_item, null);

        // set value into textview
        TextView textView = (TextView) gridView
                .findViewById(R.id.grid_item_label);
        textView.setText(mobileValues[position]);

    } else {
        gridView = (View) convertView;
    }

    return gridView;
}
.....
}

这是每个文本项的 XML

<?xml version="1.0" encoding="utf-8"?>
<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="fill_parent"
android:gravity="center"
android:orientation="vertical" >

<TextView
    android:id="@+id/grid_item_label"
    android:layout_width="match_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/cell_shape"
    android:text="@string/_1"
    tools:ignore="InefficientWeight"
    android:textSize="12sp" >
</TextView>

</LinearLayout>

这是每个 TextView 的形状

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools">
<solid android:color="#FFFFFF"/>
<stroke android:width="1dp" android:color="#777777" />
</shape>

我希望我的 Gridview 像这样

您可以将在 GridView 的适配器中膨胀的 TextView 的每个 LinearLayout 的高度设置为 screenHeight/3。

在 textView 的 xml 膨胀后的 getView 中，将膨胀后的 View 转换为 LinearLayout 并将其高度设置为:

LayoutInflater li = getLayoutInflater();
LinearLayout ll = (LinearLayout) li.inflate(R.layout.menu_items, null);

int screenHeight = ((Activity) context).getWindowManager()
                    .getDefaultDisplay().getHeight();

ll.setMinimumHeight(screenHeight/3);

             "1", "2", "3", "1", "2", "3", "1", "2", "3" ,
             "1", "2", "3", "1", "2", "3", "1", "2", "3" ,
             "1", "2", "3", "1", "2", "3", "1", "2", "3" ,
             "1", "2", "3", "1", "2", "3", "1", "2", "3" ,
             "1", "2", "3", "1", "2", "3", "1", "2", "3" ,
             "1", "2", "3", "1", "2", "3", "1", "2", "3" ,
             "1", "2", "3", "1", "2", "3", "1", "2", "3" ,
             "1", "2", "3", "1", "2", "3", "1", "2", "3" };

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        requestWindowFeature(Window.FEATURE_NO_TITLE);
        setContentView(R.layout.activity_main);

        GridView gridView = (GridView) findViewById(R.id.gridView1);

        gridView.setAdapter(new myGridAdapter(this, str));

        gridView.setOnItemClickListener(new OnItemClickListener() {
            public void onItemClick(AdapterView<?> parent, View v,
                    int position, long id) {

            }

        });

    }

    public class myGridAdapter extends BaseAdapter {

        private Context context;
        private String[] mobileValues;

        public myGridAdapter(MainActivity mainActivity, String[] arrayEmpty) {
            this.context = mainActivity;
            this.mobileValues = arrayEmpty;
        }

        public View getView(int position, View convertView, ViewGroup parent) {

            LayoutInflater inflater = (LayoutInflater) context
                    .getSystemService(Context.LAYOUT_INFLATER_SERVICE);

            LinearLayout gridView;

            if (convertView == null) {

                // get layout from text_item.xml
                gridView = (LinearLayout)inflater.inflate(R.layout.text_item, null);

                int screenHeight = ((Activity) context).getWindowManager()
                        .getDefaultDisplay().getHeight();

                gridView.setLayoutParams(new GridView.LayoutParams(GridView.LayoutParams.MATCH_PARENT, screenHeight/9));


                //gridView.setMinimumHeight(screenHeight/9);
                // set value into textview
                TextView textView = (TextView) gridView
                        .findViewById(R.id.grid_item_label);
                textView.setText(mobileValues[position]); 

            } else {
                gridView = (LinearLayout) convertView;
            }

            return gridView;
        }

        @Override
        public int getCount() {
            // TODO Auto-generated method stub
            return mobileValues.length;
        }

        @Override
        public Object getItem(int position) {
            // TODO Auto-generated method stub
            return null;
        }

        @Override
        public long getItemId(int position) {
            // TODO Auto-generated method stub
            return 0;
        }
    }

}

在 getView 中我所做的是将 text_item.xml 膨胀 9x9 次，其中我动态地将 text_item 的布局高度设置为 screenHeight/9。让我知道它是否适合您。
