5.AutoCompleteTextView、自定义广播

新建信息

布局：自动出来的是系统的组件，里面是listview，写ontextchanglis也行
  1. <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  2.     android:layout_width="match_parent"
  3.     android:layout_height="match_parent"
  4.     android:padding="5dp"
  5.     android:orientation="vertical" >
  6. 。。。。。
  7.         <!--  android:completionThreshold="1" 当弹出建议框的时候，actv中输入的字符的个数  -->
  8.         <AutoCompleteTextView 
  9.             android:layout_width="0dp"
  10.             android:layout_weight="2"
  11.             android:layout_height="wrap_content"
  12.             android:id="@+id/actv"
  13.             android:textColor="@android:color/black"
  14.             android:completionThreshold="1"
  15.             android:background="@drawable/et_common_bg"
  16.             />
  17.         <ImageView 
  18.             android:layout_width="wrap_content"
  19.             android:layout_height="wrap_content"

  21.             android:id="@+id/iv_select_contact"
  22.             />
  23.     </LinearLayout>
  25.     
  26.     <EditText 
  27.         android:layout_width="match_parent"
  28.         android:layout_height="0dp"
  29.         android:layout_weight="2"
  30.         android:background="@drawable/et_common_bg"
  31.         android:id="@+id/et_input_msg"
  32.         android:gravity="top"//写上top默认就在上面
  33.         />
  35.     <Button

  43.         android:text="发送短信" />
  44.     
  45. </LinearLayout>

Tools 添加方法
  1. 	/**
  2. 	 * 发送短信
  3. 	 * @param ctx
  4. 	 * @param msg 短信内容
  5. 	 * @param address 收信人的电话号码
  6. 	 */
  7. 	public static void sendMessage(Context ctx, String msg, String address) {
  8. 		
  9. 		SmsManager smsManager = SmsManager.getDefault();
  10. 		//对短信内容进行切割，防止，内容过长。
  11. 		ArrayList<String> msgList = smsManager.divideMessage(msg);
  12. 		
  13. 		//用于启动广播的意图
  14. 		Intent intent = new Intent("com.itheima.smsmanager39.receive.SmsSendSuccessReceiver");
  15. 		
  16. 		PendingIntent sentIntent = PendingIntent.getBroadcast(ctx, 88, intent, PendingIntent.FLAG_ONE_SHOT);
  17. 		
  18. 		for (int i = 0; i < msgList.size(); i++) {
  19. 			String oneMsg = msgList.get(i);
  20. 			smsManager.sendTextMessage(
  21. 					address, // 收信人号码
  22. 					null, // 短信服务中心的号码
  23. 					oneMsg, // 要发送的内容
  24. 					sentIntent,  // 我们发送成功后的，隐式意图
  25. 					null); // 对方接收成功后的，隐式意图
  26. 		}
  27. 		
  28. 		insertMsg2msmDb(ctx,msg,address);
  29. 		
  30. 	}
  32. 	/**
  33. 	 * 将短信内容插入系统数据库
  34. 	 * @param ctx
  35. 	 * @param msg 短信内容
  36. 	 * @param address 收短信的号码 
  37. 	 */
  38. 	private static void insertMsg2msmDb(Context ctx, String msg, String address) {
  39. 		
  40. 		ContentValues values = new ContentValues();
  41. 		
  42. 		values.put("address", address); 
  43. 		
  44. 		values.put("body", msg); 
  45. 		
  46. 		values.put("type", MyConstants.TYPE_SEND); 
  47. 		
  48. 		ctx.getContentResolver().insert(MyConstants.URI_SMS, values);
  49. 		
  50. 	}
自定义广播，需要清单文件写action
  1. public class SmsSendSuccessReceiver extends BroadcastReceiver{
  3. 	@Override
  4. 	public void onReceive(Context context, Intent intent) {
  5. 		Toast.makeText(context, "短信已经发送成功", 0).show();
  6. 	}
  7. }
清单文件：注意输入的模式就变了，发送按钮在输入法上面了
  1.    <activity
  2.             android:name="com.itheima.smsmanager39.NewMessageUI"
  3.             android:label="@string/app_name" 
  4.             android:windowSoftInputMode="adjustResize">
  5.         </activity>
