仿爱奇艺界面（4）

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

	@Override
	protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.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;
	}

	@Override
	public int getCount() {
		// TODO Auto-generated method stub
		return test1.length;
	}

	@Override
	public Object getItem(int arg0) {
		// TODO Auto-generated method stub
		return null;
	}

	@Override
	public long getItemId(int arg0) {
		// TODO Auto-generated method stub
		return 0;
	}

	@Override
	public View getView(int arg0, View arg1, ViewGroup arg2) {
		// TODO Auto-generated method stub
		if (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。
