你可能想试试开源tinybus。有了它，震动检测就像这样简单。

public class MainActivity extends Activity {

    private Bus mBus;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        ...

        // Create a bus and attach it to activity
        mBus = TinyBus.from(this).wire(new ShakeEventWire());
    }

    @Subscribe
    public void onShakeEvent(ShakeEvent event) {
        Toast.makeText(this, "Device has been shaken", 
                Toast.LENGTH_SHORT).show();
    }

    @Override
    protected void onStart() {
        super.onStart();
        mBus.register(this);
    }

    @Override
    protected void onStop() {
        mBus.unregister(this);
        super.onStop();
    }
}

它采用地震仪进行振动检测。
