仿爱奇艺界面（四）
搜索Activity的java内容虽然不多，只是找到两个gridView然后分别给他们设置适配器，但是布局文件里面包含的信息还是很丰富的。
SearchActivity：
?
public class SearchActivity extends Activity {GridView mHotGridView, mHistoryGridView;//热门搜索和搜索历史@Overrideprotected void onCreate(Bundle savedInstanceState) {// TODO Auto-generated method stubsuper.onCreate(savedInstanceState);setContentView(R.layout.search_activity);prepareView();}private void prepareView() {mHotGridView = (GridView) findViewById(R.id.hot_search_grid);mHotGridView.setAdapter(new GridAdapter(this));mHistoryGridView = (GridView) findViewById(R.id.history_search_grid);mHistoryGridView.setAdapter(new GridAdapter(this));}}?接下来是适配器GridAdapter的代码，学习了gridView的话应该是轻车熟路了，把test1里面的倒霉熊什么的都写上去：
public class GridAdapter extends BaseAdapter {Context mContext;String[] test1 = new String[] { "开心魔法", "奋斗", "导火索", "碟中谍4", "碟中碟3","美人心计", "倒霉熊", "火影忍者", "喜洋洋", "北京爱情故事" };public GridAdapter(Context cnt) {this.mContext = cnt;}@Overridepublic int getCount() {// TODO Auto-generated method stubreturn test1.length;}@Overridepublic Object getItem(int arg0) {// TODO Auto-generated method stubreturn null;}@Overridepublic long getItemId(int arg0) {// TODO Auto-generated method stubreturn 0;}@Overridepublic View getView(int arg0, View arg1, ViewGroup arg2) {// TODO Auto-generated method stubif (arg1 == null) {arg1 = LayoutInflater.from(mContext).inflate(R.layout.search_grid_item, null);}TextView tv = (TextView) arg1.findViewById(R.id.title);tv.setText(test1[arg0]);return arg1;}}?布局文件里面用到的东西很多了，我把重点的讲下transparent这是图片重叠透明穿透，就是两张png的图片合在一块，不是覆盖。这里的效果就是摁下字，背景变了。

PS：上面有些东西就没全部贴出来了，待会把整个源码贴上去，自己找了。
