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

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="5dp"
    android:orientation="vertical" >
。。。。。
        <!--  android:completionThreshold="1" 当弹出建议框的时候，actv中输入的字符的个数  -->
        <AutoCompleteTextView 
            android:layout_width="0dp"
            android:layout_weight="2"
            android:layout_height="wrap_content"
            android:id="@+id/actv"
            android:textColor="@android:color/black"
            android:completionThreshold="1"
            android:background="@drawable/et_common_bg"
            />
        <ImageView 
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:background="@drawable/select_contact_bg"
            android:id="@+id/iv_select_contact"
            />
    </LinearLayout>
    
    <EditText 
        android:layout_width="match_parent"
        android:layout_height="0dp"
        android:layout_weight="2"
        android:background="@drawable/et_common_bg"
        android:id="@+id/et_input_msg"
        android:gravity="top"//写上top默认就在上面
        />
    <Button
        android:id="@+id/btn_send_msg"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_gravity="center_horizontal"
        android:background="@drawable/btn_common_bg"
        android:paddingLeft="10dp"
        android:paddingRight="10dp"
        android:text="发送短信" />
    
</LinearLayout>

代码

public class NewMessageUI extends Activity implements OnClickListener {
	private AutoCompleteTextView actv;
	private ImageView selectContact;
	
	private EditText inputMsg;
	
	protected void onCreate(android.os.Bundle savedInstanceState) {
		super.onCreate(savedInstanceState);
		
		setContentView(R.layout.activity_new_message);
		
		actv = (AutoCompleteTextView) findViewById(R.id.actv);
		selectContact = (ImageView) findViewById(R.id.iv_select_contact);
		inputMsg = (EditText) findViewById(R.id.et_input_msg);
		selectContact.setOnClickListener(this);
		findViewById(R.id.btn_send_msg).setOnClickListener(this);
		
		adapter = new ACTVAdapter(this, null);
		actv.setAdapter(adapter);
		
		adapter.setFilterQueryProvider(new FilterQueryProvider() {
			@Override
			/**
			 * 当actv 中的内容发生改变时，回调此方法 
			 * @param constraint
			 * @return
			 */
			public Cursor runQuery(CharSequence constraint) {
				
				System.out.println(constraint);
				
				Cursor cursor = getContentResolver().query(MyConstants.URI_CONTACTS, projection, "data1 like '%"+constraint+"%'", null, null);
				return cursor;
			}
		});
		
	}
	/**
	 * 要查询的列
	 */
	private String[] projection = {
			"_id","data1","display_name"
	};
	
	private final int INDEX_NAME=2;
	private final int INDEX_NUMBER=1;
	
	private ACTVAdapter adapter;
	
	class ACTVAdapter extends CursorAdapter{
		public ACTVAdapter(Context context, Cursor c) {
			super(context, c);
		}
		@Override
		/**
		 * 该方法在点击actv中弹出的listView时，将返回值设置给 actv 
		 */
		public CharSequence convertToString(Cursor cursor) {
			return cursor.getString(INDEX_NUMBER);
		}
		
		
		@Override
		public View newView(Context context, Cursor cursor, ViewGroup parent) {
			View view = View.inflate(context, R.layout.list_item_actv, null);
			
			return view;
		}
		@Override
		public void bindView(View view, Context context, Cursor cursor) {
			
			TextView name = (TextView) view.findViewById(R.id.tv_name_actv);
			TextView number = (TextView) view.findViewById(R.id.tv_number_actv);
			
			name.setText(cursor.getString(INDEX_NAME));
			number.setText(cursor.getString(INDEX_NUMBER));
		}
	}
	
	
	
	@Override
	public void onClick(View v) {
		switch (v.getId()) {
		case R.id.btn_send_msg:// 发送短信的按钮
			String address = actv.getText().toString();
			if(TextUtils.isEmpty(address.trim())){
				Toast.makeText(this, "请输入收件人号码", 0).show();
				return ;
			}
			String msg = inputMsg.getText().toString();
			if(TextUtils.isEmpty(msg.trim())){
				Toast.makeText(this, "请输入短信内容", 0).show();
				return ;
			}
			
			// 开始发送短信
			Tools.sendMessage(this, msg, address);
			
			// 清空输入框 
			inputMsg.setText("");
			
			break;
		case R.id.iv_select_contact:// 点击选择联系人的图片
			
			Intent intent = new Intent();
			intent.setAction("android.intent.action.PICK");//不能显示启动，因为有可能系统程序的类名改变了
			intent.setData(Uri.parse("content://com.android.contacts/contacts"));
//			startActivity(intent);
			startActivityForResult(intent, 99);
			
			break;
		default:
			break;
		}
	};
	@Override
	protected void onActivityResult(int requestCode, int resultCode, Intent data) {
		
		String stringExtra = data.getStringExtra("phone");
		System.out.println("stringExtra::"+stringExtra);
		
		Uri uri = data.getData();
		
		Cursor cursor = getContentResolver().query(uri, new String[]{"_id"}, null, null, null);
//		Tools.printCursor(cursor);
		cursor.moveToNext();// 返回的cursor默认指向-1行 ，
		int contactId = cursor.getInt(0); // 仅查询一列，所以列的索引值 输入 0
		
		Cursor cursor2 = getContentResolver().query(MyConstants.URI_CONTACTS, new String[]{"data1"}, " contact_id = "+contactId, null, null);
		cursor2.moveToNext();// 返回的cursor默认指向-1行 ，
		
		String number = cursor2.getString(0);
		
		actv.setText(number);
		
	}
	
	
}

Tools 添加方法

	/**
	 * 发送短信
	 * @param ctx
	 * @param msg 短信内容
	 * @param address 收信人的电话号码
	 */
	public static void sendMessage(Context ctx, String msg, String address) {
		
		SmsManager smsManager = SmsManager.getDefault();
		//对短信内容进行切割，防止，内容过长。
		ArrayList<String> msgList = smsManager.divideMessage(msg);
		
		//用于启动广播的意图
		Intent intent = new Intent("com.itheima.smsmanager39.receive.SmsSendSuccessReceiver");
		
		PendingIntent sentIntent = PendingIntent.getBroadcast(ctx, 88, intent, PendingIntent.FLAG_ONE_SHOT);
		
		for (int i = 0; i < msgList.size(); i++) {
			String oneMsg = msgList.get(i);
			smsManager.sendTextMessage(
					address, // 收信人号码
					null, // 短信服务中心的号码
					oneMsg, // 要发送的内容
					sentIntent,  // 我们发送成功后的，隐式意图
					null); // 对方接收成功后的，隐式意图
		}
		
		insertMsg2msmDb(ctx,msg,address);
		
	}
	/**
	 * 将短信内容插入系统数据库
	 * @param ctx
	 * @param msg 短信内容
	 * @param address 收短信的号码 
	 */
	private static void insertMsg2msmDb(Context ctx, String msg, String address) {
		
		ContentValues values = new ContentValues();
		
		values.put("address", address); 
		
		values.put("body", msg); 
		
		values.put("type", MyConstants.TYPE_SEND); 
		
		ctx.getContentResolver().insert(MyConstants.URI_SMS, values);
		
	}

自定义广播，需要清单文件写action

public class SmsSendSuccessReceiver extends BroadcastReceiver{
	@Override
	public void onReceive(Context context, Intent intent) {
		Toast.makeText(context, "短信已经发送成功", 0).show();
	}
}

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

   <activity
            android:name="com.itheima.smsmanager39.NewMessageUI"
            android:label="@string/app_name" 
            android:windowSoftInputMode="adjustResize">
        </activity>
