Question

你好，我是android的新手，所以我想知道如何获取android中的时间间隔所以请帮我找到这个程序的时间间隔？我的老师说时间戳减去一次到另一个时间？去做吧？

public class MainActivity extends Activity {

    private Button myLocation;
    private TextView myAddress;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        myLocation = (Button) findViewById(R.id.location);
        myAddress = (TextView) findViewById(R.id.address);

        myLocation.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View v) {
                getMyLocationAddress();
            }
        });

    }

    public void getMyLocationAddress() {

        Geocoder geocoder= new Geocoder(this, Locale.ENGLISH);

        try {
            // Place your latitude and longitude
            List<Address> addresses = geocoder.getFromLocation(28.437582, 76.995242, 1);

            if (addresses != null) {
                Address fetchedAddress = addresses.get(0);
                StringBuilder strAddress = new StringBuilder();
                for (int i = 0; i < fetchedAddress.getMaxAddressLineIndex(); i++) {
                    strAddress.append(fetchedAddress.getAddressLine(i)).append("\n");
                }
                myAddress.setText("I am at: " + strAddress.toString());
            } else
              myAddress.setText("No location found..!");
        } catch (IOException e) {
             e.printStackTrace();
             Toast.makeText(getApplicationContext(),"Could not get a address..!",Toast.LENGTH_LONG).show();
        }
    }
}

目前还不清楚你在问什么，但是你可以得到当前的时间（从1970年开始）：

long time= System.currentTimeMillis();

如果获取当前时间并执行您选择的操作并与保存的实例进行比较：

long start = long time= System.currentTimeMillis();
//Do method calls
long totalTimeSinceStart = System.currentTimeMillis() - start;

我怎样才能得到这个程序的时间间隔？
