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" ><ImageViewandroid:id="@+id/iv_image"android:layout_width="wrap_content"android:layout_height="60dp"android:src="@drawable/app" /><TextViewandroid: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 {@Overridepublic int getCount() {// TODO Auto-generated method stubreturn titles.length;}@Overridepublic Object getItem(int position) {// TODO Auto-generated method stubreturn null;}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn 0;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubView 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() {@Overridepublic void onItemClick(AdapterView<?> parent, View view,int position, long id) {// TODO Auto-generated method stub
                ConsoleItemClick(position);}});

6、显示
