Android开发学习笔记-GridView的动态显示

1、添加GridItem布局文件

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="wrap_content"    android:layout_height="wrap_content"    android:gravity="center"    android:orientation="vertical" >    <ImageView        android:id="@+id/iv_image"        android:layout_width="wrap_content"        android:layout_height="60dp"                android:src="@drawable/app" />    <TextView        android:id="@+id/tv_title"        android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:text="设置中心" /></LinearLayout>

2、主界面添加GridView

 <GridView         android:id="@+id/grid_main"         android:layout_width="wrap_content"        android:layout_height="wrap_content"        android:numColumns="3"        >            </GridView>

3、添加自定义适配器类,并对自定义griditem布局文件中的控件进行设置值

protected class MyGridAdapter extends BaseAdapter {        @Override        public int getCount() {            // TODO Auto-generated method stub            return titles.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;        }        @Override        public View getView(int position, View convertView, ViewGroup parent) {            // TODO Auto-generated method stub            View view = View.inflate(MainActivity.this, R.layout.list_item_main, null);            TextView title =  (TextView) view.findViewById(R.id.tv_title);            title.setText(titles[position]);                        return view;        }

4、设置主界面中的GridItem

private GridView grid_main;private MyGridAdapter adapter;private static String []titles = {"设置中心1","设置中心2","设置中心3","设置中心4","设置中心5","设置中心6","设置中心7","设置中心8","设置中心9"};....grid_main = (GridView) findViewById(R.id.grid_main);adapter = new MyGridAdapter();grid_main.setAdapter(adapter);

5、添加item点击事件

grid_main.setOnItemClickListener(new OnItemClickListener() {            @Override            public void onItemClick(AdapterView<?> parent, View view,                    int position, long id) {                // TODO Auto-generated method stub                ConsoleItemClick(position);            }        });
