ContentProvider共享XML数据

APP-A：

String[] columns = new String[] { "UserId", "Name", "Identity" };
MatrixCursor stringCursor = new MatrixCursor(columns);
String row[] = new String[3];
row[0] = "";
row[1] = "";
row[2] = "";
stringCursor.addRow(row);
return stringCursor;

其他调用APP

Uri uri = Uri.parse("content://xxxx/shareData");
Cursor cursor = getContentResolver().query(uri,null,null,null,null);

if(cursor.moveToFirst()){
    String UserId = cursor.getString(cursor.getColumnIndex("UserId"));
    Log.e("Main2Activity", "onClick: "+UserId );
    String Name = cursor.getString(cursor.getColumnIndex("Name"));
    Log.e("Main2Activity", "onClick: "+Name );
    String Identity = cursor.getString(cursor.getColumnIndex("Identity"));
    Log.e("Main2Activity", "onClick: "+Identity );
}
cursor.close();
