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：
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@color/White" android:orientation="vertical" > <RelativeLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:background="@drawable/bg" android:gravity="center" android:orientation="horizontal" > <ImageButton android:id="@+id/send_left" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:background="@drawable/pre" > </ImageButton> <LinearLayout android:id="@+id/send_middle" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_toLeftOf="@+id/send_right" android:layout_toRightOf="@id/send_left" android:gravity="center" android:orientation="vertical" > <ImageButton android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/newstatus" android:gravity="center" > </ImageButton> </LinearLayout> <ImageButton android:id="@+id/send_right" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:background="@drawable/send" > </ImageButton> </RelativeLayout> <RelativeLayout android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_weight="1" > <EditText android:id="@+id/editStatus" android:layout_width="fill_parent" android:layout_height="fill_parent" android:padding="3dip" android:background="@color/White" android:gravity="top" android:hint="您想说点什么呢..."> </EditText> <ImageView android:id="@+id/thumbImage" android:layout_height="wrap_content" android:layout_width="wrap_content" android:padding="3dip" android:layout_alignBottom="@id/editStatus" android:layout_alignLeft="@id/editStatus" /> <TextView android:id="@+id/statusCount" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignBottom="@id/editStatus" android:layout_alignRight="@id/editStatus" /> </RelativeLayout> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" > <GridView android:id="@+id/statusTool" android:layout_width="fill_parent" android:layout_height="30dip" android:background="@drawable/maintab_toolbar_bg" android:gravity="center" android:numColumns="4" > </GridView> </LinearLayout></LinearLayout>
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<HashMap<String,Object>> 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;}@Overridepublic int getCount() {// TODO Auto-generated method stubreturn imageResourceArray.length;}@Overridepublic Object getItem(int arg0) {// TODO Auto-generated method stubreturn imageResourceArray[arg0];}@Overridepublic long getItemId(int position) {// TODO Auto-generated method stubreturn position;}@Overridepublic View getView(int position, View convertView, ViewGroup parent) {// TODO Auto-generated method stubLayoutInflater 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<String,Object> 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 stubsuper.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
