fragment中怎么读取数据库的数据

d broadcastUpdate(final String action,final BluetoothGattCharacteristic characteristic){

final Intent intent = new Intent(action)

if(UUID_HEART_RATE_MEASUREMENT.equals(characteristic.getUuid())){

int flag = characteristic.getProperties()

int format = -1

if((flag &0x01)!= 0){

format = BluetoothGattCharacteristic.FORMAT_UINT16

Log.d(TAG,"Heart Rate format UINT16.")

}else{

format = BluetoothGattCharacteristic.FORMAT_UINT8

Log.d(TAG,"Heart Rate format UINT8.")

}

fragment可以在xml中添加，也可以直接新建ListViewFragemnt extends Fragment ，在这种方法的OnCreateView方法中，使用layoutinflator加载xml文件View，返回View，然后就是根据View去初始化ListView，数据直接从数据库取出，在适配器Adapter中更新显示数据。

View view = inflater.inflate(R.layout.fragment_record, null)

这句话应该是View view = inflater.inflate(R.layout.fragment_record, container,false)
