安卓(Android)九宫格布局介绍

1、界面如下：

2、代码介绍：

  1、布局文件gridview_item.xml

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="center"
    android:orientation="vertical" >

    <ImageView
        android:id="@+id/img"
        android:layout_width="60dp"
        android:layout_height="60dp"
        android:layout_marginTop="10dp"
        android:src="@drawable/xmgn407" />
    <TextView
        android:id="@+id/text"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="2dp"
        android:layout_gravity="center"
        android:textColor="#FFF"
        android:text="文字"
        />

</LinearLayout>

2、activity代码

public class MainActivity extends AppCompatActivity {
    private List<Map<String, Object>> dataList;
    private SimpleAdapter adapter;
    private GridView gridView;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        gridView = (GridView) findViewById(R.id.gridview);
        //初始化数据
        initData();
        String[] from = {"imgId", "text"};
        int[] to = {R.id.img, R.id.text};
        //调用自带的九宫格初始化适配器
        adapter = new SimpleAdapter(this, dataList, R.layout.gridview_item, from, to);

        gridView.setAdapter(adapter);

        gridView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
            @Override
            public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
                                    long arg3) {
                AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
                builder.setTitle("提示").setMessage(dataList.get(arg2).get("text").toString()).create().show();
            }
        });
    }

    void initData() {
        //图标
        int icno[] = {
                R.drawable.xmgn407, R.drawable.xmgn407, R.drawable.xmgn407,
                R.drawable.xmgn407, R.drawable.xmgn407, R.drawable.xmgn407,
                R.drawable.xmgn407, R.drawable.xmgn407, R.drawable.xmgn407
        };
        //图标下的文字
        String name[] = {"图标1", "图标1", "图标1", "图标1", "图标1", "图标1", "图标1", "图标1", "图标1"};
        dataList = new ArrayList<Map<String, Object>>();
        for (int i = 0; i < icno.length; i++) {
            Map<String, Object> map = new HashMap<String, Object>();
            map.put("imgId", icno[i]);
            map.put("text", name[i]);
            dataList.add(map);
        }
    }
}
