我有一个循环进度条,我想要用它来测量速度,就像汽车车速表,但我不知道如何做到这一点SOMETHING LIKE THIS。或者如果可以使用循环进度条。所以我正在做的是将速度存储在一个变量中,并使用progressbar.setProgress来获得速度。但它没有用,因为我觉得不对,所以欢迎任何建议或建议。
MainActivity:
public class MainActivity extends AppCompatActivity {
ProgressBar mprogressBar;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mprogressBar = (ProgressBar) findViewById(R.id.circular_progress_bar);
ObjectAnimator anim = ObjectAnimator.ofInt(mprogressBar, "progress", (int)speeeeed, 25);
Log.e("valor de speed", Double.toString(speeeeed));
mprogressBar.setProgress((int) speeeeed);
anim.setDuration(15000);
anim.setInterpolator(new DecelerateInterpolator());
anim.start();
}
LocationListener locationListener = new LocationListener() {
public void onLocationChanged(Location location) {
float Real =(location.getSpeed()*3600/1000);
String convertedSpeed = String.format("%.2f",Real);
TVKm.setText(convertedSpeed);
}
public void onStatusChanged(String provider, int status,
Bundle extras) {
}
public void onProviderEnabled(String provider) {
}
public void onProviderDisabled(String provider) {
}
};
