创建Contentprovider，

创建Contentprovider:

1. 创建一个provider----ExampleContentProvider

设计Content URIs(a. 设计authority b. 设计path c.处理content URI IDs d.Content URI patterns

)定义MIME Types（getType()One of the required methods that you must implement for any provider. getStreamTypes()A method that you're expected to implement if your provider offers files.）

ContentValues values = new ContentValues() ;values.put("WORD", "abcd") ;Uri uri = this.getContentResolver().insert(Uri.parse("content://com.hualu.contentprovider/mains"),values) ;String id = uri.getPathSegments().get(1) ;Cursor cAll = this.getContentResolver().query(Uri.parse("content://com.hualu.contentprovider/mains"), null, null, null,null);Cursor c = this.getContentResolver().query(Uri.parse("content://com.hualu.contentprovider/main/1"), null, null, null,null);Toast.makeText(this, "insert success id = " + id + " ," +" \r\n All = " + cAll.getCount() + " , " +"\r\n one = " + c.getCount(),Toast.LENGTH_SHORT).show() ;
