ContentProvider

<ContentProviderBinder name = "name1" dependency = "name2">
<ContentProviderBinder name = "name2">
triggers name1 name2 inquiry after inquiry ended, 
name1 name2 queries can use variables.
And if the data changes name2 re-query, it will trigger a re-query name1.
  • content provider provides application information query universal interface, define a new xml code to query content provider, and query the binding information to the variables used to display information about third-party applications, as long as third-party applications to provide the corresponding The content provider. For example, you can display weather information, e-mail, to-do, notes, etc., you can also write an application to query any information you want by content provider to provide to the lock screen to use.

  • VariableBinders: the definition of variables to bind to the source, currently only supports content provider.
  • ContentProviderBinder: Define a content provider and bind to it a source of variable
  • uri: content provider uri, which specifies the content provider selection
  • uriFormat: If uri need to add a variable, you can use the format, you need to work and uriParas
  • uriParas: Text element of the same format
  • columns: Column names need to query, separated by commas
  • where: query, with SQL
  • args: "where" parameters.
  • order: sorted, with SQL
  • countName: The number of queries structure is bound to the variable name
  • Variable: Given a bind variable
  • name: variable name
  • type: content provider data type: string / double / float / int / long
  • column: variable is bound to the name of the column.
  • row: number of rows variable is bound to, the default is 0.

Broadcast

  • BroadcastBinder: to receive broadcast messages, are <VariableBinders>, this function allows the interaction between the different modules Variety
  • You can get to carry the extra broadcast information and updates to the specified variable
  • Support Trigger: receiving the broadcast radio, updatable variables can trigger a number of command
    <BroadcastBinder name = "" action = "">
 <Variable name = "variable_name1" type = "int" extra = "testNum" default = "" />
 <Variable name = "variable_name2" type = "string" extra = "testStr" default = "" />
 <Trigger>
   <Command target = "" value = "" />
 </ Trigger>
</ BroadcastBinder>
  • action: Specifies the broadcast name
  • name: variable name
  • extra: broadcast broadcasting extra name
  • type: type string, int, integer, float, double, long

Examples

<VariableBinders>
   <BroadcastBinder action = "wallpaper_day">
     <Variable name = "number" type = "int" default = "1" />
