我正在尝试使用以下方法获取电话:

private String getMyPhoneNumber() {
    TelephonyManager mTelephonyMgr;

    mTelephonyMgr = (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE); 
    //String imsi = mTelephonyMgr.getSubscriberId();
    String phnNo = mTelephonyMgr.getLine1Number();
    if (phnNo == null) {
        phnNo = getNoFromWatsApp();
    }
    return phnNo;
}

private String getNoFromWatsApp(){
    AccountManager am = AccountManager.get(this);
    Account[] accounts = am.getAccounts();
    String phoneNumber = "";

    for (Account ac : accounts) {
        String acname = ac.name;
        String actype = ac.type;
        // Take your time to look at all available accounts
        if(actype.equals("com.whatsapp")) {
            phoneNumber = ac.name;
        }
    }
    return phoneNumber;
}

但每次我得到一个空电话号码.我甚至试图从WhatsApp获得电话号码,但它正在返回"WhatsApp"而不是电话号码.有没有其他方法可以解决这个问题？

我Tileview使用TileView库显示一个大图像

现在我想在特定的瓷砖上显示时在矩形边界显示一个圆圈.

如何点击哪个瓷砖？以及如何显示BitMmap上面的那个瓷砖？

public class LargeImageTileViewActivity extends TileViewActivity {
    TileView tileView;
    @Override
    public void onCreate( Bundle savedInstanceState ) {

        super.onCreate( savedInstanceState );

        // multiple references
        tileView = getTileView();

        // by disabling transitions, we won't see a flicker of background color when moving between tile sets
        tileView.setTransitionsEnabled( false );

        // size of original image at 100% scale
        tileView.setSize( 2835, 4289 );

        // detail levels
        tileView.addDetailLevel( 1.000f, "tiles/painting/1000/%col%_%row%.jpg");
        tileView.addDetailLevel( 0.500f, "tiles/painting/500/%col%_%row%.jpg");
        tileView.addDetailLevel( 0.250f, "tiles/painting/250/%col%_%row%.jpg");
        tileView.addDetailLevel( 0.125f, …
