问题描述
嘿家伙,我有一个关于如何使一个按钮,随机移动的问题每秒
Hey Guys i have a Question about how to make a button randomly move every second
黑瓦是一个按钮
所以我要让它在随机移动的每一秒或更快
so i want to make it move randomly in every second or more fast
这是我的XML
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:background="@drawable/backgroundblank" >
<Button
android:id="@+id/Button01"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:background="@drawable/black1" />
</RelativeLayout>
这是在code
public class tested extends Activity {
Button buttonblack;
int score=0;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.tested);
buttonblack = (Button)findViewById(R.id.black1);
buttonblack.setOnClickListener(new View.OnClickListener() {
public void onClick(View v){
//score+10(i dont know how to make score +10 if the button clicked)
//if the button clicked
//Do some logic here
}
});
if (score = 100){
//the speed of move are increase more fast
}
}
有人能帮助我吗?
anyone can help me?
推荐答案
首先,你应该得到的屏幕尺寸
First you should get the screen size
public static Point getDisplaySize(@NonNull Context context) {
Point point = new Point();
WindowManager manager = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
manager.getDefaultDisplay().getSize(point);
return point;
}
然后,你应该得到一个随机x和随机y位置的按钮即可进入,使得其仍然在屏幕上
Then you should get a random x and random y position for the button to go to so that its still on screen
private void setButtonRandomPosition(Button button){
int randomX = new Random().nextInt(getDisplaySize(this).x);
int randomY = new Random().nextInt(getDisplaySize(this).y);
button.setX(randomX);
button.setY(randomY);
}
最后,要做到这一点每一秒
Finally to make this happen every second
private void startRandomButton(Button button) {
Timer timer = new Timer();
timer.schedule(new TimerTask() {
@Override
public void run() {
setButtonRandomPosition(button);
}
}, 0, 1000);//Update button every second
}
在上创建运行它像这样
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
WindowManager.LayoutParams.FLAG_FULLSCREEN);
setContentView(R.layout.tested);
buttonblack = (Button)findViewById(R.id.black1);
startRandomButton(blackbutton);
}
