Android：SNS客户端开发五：发送微博界面设计

之前的我们已经通过OAuth认证，通过了新浪的授权并且取得了用户相关的信息。今天开始我们来发送一条微博试试。首先是发送微博界面的布局设计。先看布局代码：

我们为底部的GridView添加一个适配器，用来显示底部按钮相关内容

/*
 * 发送微博，评论，转发页面底部GridView工具栏Adapter
 */
public class BottomBarAdapter extends BaseAdapter{

	private ArrayList> data;
	private Context context;
	private String[] menuNameArray;
	private int[] imageResourceArray;
	
	
	public BottomBarAdapter(String[] menuNameArray,
			int[] imageResourceArray, Context context){
		this.imageResourceArray = imageResourceArray;
		this.menuNameArray = menuNameArray;
		this.context = context;
	}
	
	@Override
	public int getCount() {
		// TODO Auto-generated method stub
		return imageResourceArray.length;
	}

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

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

	@Override
	public View getView(int position, View convertView, ViewGroup parent) {
		// TODO Auto-generated method stub
		LayoutInflater flater = (LayoutInflater)context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
		convertView = flater.inflate(R.layout.bottombar, null);
		TextView textview = (TextView)convertView.findViewById(R.id.buttombarText);
		ImageView imageview = (ImageView)convertView.findViewById(R.id.buttombarImage);
	//	HashMap button = data.get(position);
		String name = menuNameArray[position];
		int pic = imageResourceArray[position];
		if(name!=""){
			textview.setText(name);
		}else{
			textview.setVisibility(View.GONE);
		}
		imageview.setImageResource(pic);
		return convertView;
	}

}

 接下来在addStatusActivity上我们来实现这个布局，并为GridView添加适配器

public class AddStatusActivity extends Activity {

	private Context context;
private GridView statusTool;
	/** 底部菜单图片 **/
	int[] detail_toolbar_image_array = { R.drawable.pic, R.drawable.at,
			R.drawable.topic, R.drawable.face };
	/** 底部菜单文字 **/
	String[] detail_toolbar_name_array = { "", "", "", "" };

	private final int TOOLBAR_ITEM_PIC = 0;// 图片
	private final int TOOLBAR_ITEM_AT = 1;// @
	private final int TOOLBAR_ITEM_TOPIC = 2;// 话题
	private final int TOOLBAR_ITEM_EMMOTION = 3;// 表情

protected void onCreate(Bundle savedInstanceState) {
		// TODO Auto-generated method stub
		super.onCreate(savedInstanceState);
		setContentView(R.layout.addstatus);
                                this.context = this;
		setView();

	}
/*
 * 建立视图
 */
	private void setView() {
	statusTool = (GridView) findViewById(R.id.statusTool);
	statusTool.setAdapter(new BottomBarAdapter(detail_toolbar_name_array,detail_toolbar_image_array, context));
	}
}

  注： 我们可以在布局文件中看到有一个id为thumbImage的ImageView，以及一个id为statusCount的TextView。这两个控件分别是用来显示在写微博时添加的图片，以及统计微博已经输入的字数。具体的实现方法将在后面的几篇博文中提到。我们先来看看效果图
