我正在制作一个应用程序,根据发件人编号在收件箱中搜索邮件.这是我的代码:

public void onClick(View v)
{
    Toast.makeText(this, "search", Toast.LENGTH_LONG).show();
    final Uri SMS_INBOX = Uri.parse("content://sms/inbox");

    String[] colList = {"address", "body"};

    Cursor c = getContentResolver().query(SMS_INBOX, colList, null, null,"DATE desc");

    String yz= String.valueOf(c.getCount());
    Toast.makeText(this, yz, Toast.LENGTH_LONG).show();

    if(c.moveToFirst())
    {
        Toast.makeText(this, searchtxt.getText(), Toast.LENGTH_LONG).show();

        for(int i=0;i<c.getCount();i++)
        {
            String number=c.getString(c.getColumnIndexOrThrow("address")).toString();
            boolean match = number.toUpperCase().indexOf(searchtxt.getText().toString()) != -1; 

            if (match)
            {
                Toast.makeText(this, String.valueOf(i), Toast.LENGTH_LONG).show();
                String  body= c.getString(c.getColumnIndexOrThrow("body")).toString();
                tv.setText(tv.getText() + "\n" + body);
            }
            c.moveToNext();
        }
    }
    else
    {
        Toast.makeText(this, "Inside else", Toast.LENGTH_LONG).show();
    }

    c.close();
}

上面的代码工作正常,但它检索收件箱中的所有邮件.我希望它应该只检索那些与发件人号码匹配的邮件.为此,我尝试使用LIKE子句进行查询,但是使用它返回0条记录.使用LIKE子句的正确方法是什么.这是我尝试使用LIKE的代码
