public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.vitesse);
gpsManager = new GPSManager();
gpsManager.startListening(getApplicationContext());
gpsManager.setGPSCallback(this);
Typeface tf = Typeface.createFromAsset(getAssets(),
"font/DS-DIGI.TTF");
TextView loding =(TextView)findViewById(R.id.info_message);
loding.setTypeface(tf);
AlphaAnimation fadeIn = new AlphaAnimation(0.0f , 1.0f ) ;
AlphaAnimation fadeOut = new AlphaAnimation( 1.0f , 0.0f ) ;
loding.startAnimation(fadeIn);
loding.startAnimation(fadeOut);
fadeIn.setDuration(500);
fadeOut.setDuration(1200);
fadeOut.setStartOffset(1200+fadeIn.getStartOffset()+1200);
measurement_index = AppSettings.getMeasureUnit(this);
}
我想重复这个 textview loding 动画,直到从 GPS 获得信息
