我正在做一个类似于算盘的时钟。我的问题是我无法理解为什么我的图像每秒都会重置，而不是继续向右。我的想法是我可能需要使用不同类型的动画？到目前为止，这是我的代码：
public class MainActivity extends Activity implements AnimationListener {
Button start, stop;
TextView time;
LinearLayout layout;
Animation movement;
private Handler mHandler = new Handler();
private long startTime;
private long elapsedTime;
private final int REFRESH_RATE = 1000;
private String seconds;
private long secs;
private boolean stopped = false;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
start = (Button) findViewById(R.id.buttonStart);
start.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
// Start animation on each image
if(stopped){
startTime = System.currentTimeMillis() - elapsedTime;
}
else{
startTime = System.currentTimeMillis();
}
mHandler.removeCallbacks(startTimer);
mHandler.postDelayed(startTimer, 0);
}
});
stop = (Button) findViewById(R.id.buttonStop);
stop.setOnClickListener(new View.OnClickListener() {
public void onClick(View view) {
mHandler.removeCallbacks(startTimer);
stopped = true;
}
});
time = (TextView) findViewById(R.id.textTime);
// Get the layouts
layout = (LinearLayout) findViewById(R.id.linearLayout1);
// Create animation for right image
movement = AnimationUtils.loadAnimation(this, R.layout.animation_test);
movement.setAnimationListener(this);
}
// Listen for animations to be finished
// There are more efficient ways, I'm just being lazy.
public void onAnimationEnd(Animation animation) {
// or do whatever it is you wanted to do here, like launch another activity?
}
public void onAnimationRepeat(Animation animation) {
}
public void onAnimationStart(Animation animation) {
}
private Runnable startTimer = new Runnable() {
public void run() {
elapsedTime = System.currentTimeMillis() - startTime;
update(elapsedTime);
mHandler.postDelayed(this,REFRESH_RATE);
}
};
private void update (float time){
secs = (long)(time/1000);
layout.startAnimation(movement);
secs = secs % 60;
seconds=String.valueOf(secs);
if(secs == 0){
seconds = "00";
}
if(secs <10 && secs > 0){
seconds = "0"+seconds;
}
/* Setting the timer text to the elapsed time */
((TextView)findViewById(R.id.textTime)).setText(seconds);
}
}
我的animation.xml如下
<translate xmlns:android="http://schemas.android.com/apk/res/android"
android:fromXDelta="0"
android:toXDelta="15%p"
android:fromYDelta="0"
android:toYDelta="0%"
android:duration="500"
android:zAdjustment="top"/>
我处于停滞状态，一直在尝试通读开发部分，但我找不到正确的解决方案，或者必须忽略某些东西。
