求助！！！getString(）返回的值是字符创类型吗？
while(mqCur.moveToNext()){
String myname=null;
String mynumber=null;
String a="alian";
myname=mqCur.getString(mqCur.getColumnIndex(People.NAME));
mynumber=mqCur.getString(mqCur.getColumnIndex(People.NUMBER));
if(myname=a)
{
Toast.makeText(this,myname+" "+mynumber, Toast.LENGTH_SHORT).show();
}
