仿腾讯手机管家火箭发射
好久没有写过博客了，前段时间一个项目中用到了浮点（漂浮在窗体上），于是突发灵感发现可以实现类似于腾讯手机管家火箭升空效果
实现步骤：1：新建一个类 名为RocketView(用来显示浮点，当手指拖动浮点变成火箭图标)
2：新建一个类 名LaunchView（火箭发射台，当手指拖动RocketView浮点到指定位置释放手指后 火箭深空）
3：在activity中调用RocketView的显示浮点方法进行演示
4：总结

/**

*/
public class LaunchView extends RelativeLayout{
private static final String TAG = LaunchView.class.getSimpleName();
private WindowManager wm;
private WindowManager.LayoutParams wlp;
private Context ctx;
public int x;//发射台的x坐标
public int y;//发射台的y坐标
public int r;//待中心点的半径
private Handler handler=new Handler(){
public void handleMessage(android.os.Message msg) {
};
};
public ImageView ivfire;
public LaunchView(Context context) {
this(context, null);
}
public LaunchView(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
public LaunchView(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
ctx=context;
wm=(WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
wlp=new WindowManager.LayoutParams();
ViewGroup.LayoutParams vlp=new ViewGroup.LayoutParams(-1,DimensionUtil.dip2px(context, 108));
this.setLayoutParams(vlp);
this.setBackgroundResource(R.drawable.rocket_base);
ivfire = new ImageView(context);
ivfire.setScaleType(ScaleType.FIT_XY);
setImageFire();
RelativeLayout.LayoutParams rlp=new RelativeLayout.LayoutParams((int) (DimensionUtil.getWidth(context)/4.5)*2,(int) (DimensionUtil.getWidth(context)/4.5));
rlp.addRule(CENTER_IN_PARENT);
this.addView(ivfire, rlp);
r=(int) (DimensionUtil.getWidth(context)/4.5);
x=DimensionUtil.getWidth(context)/2;
y=DimensionUtil.getHeight(context)-r;
Log.i(TAG, "x:"+x+" y:"+y+" r:"+r);
}
public void setImageFire( ){
ivfire.setBackgroundResource(R.drawable.rocket_fire1);
}
public void isShowFire(boolean isshow){
ivfire.setVisibility(isshow?View.VISIBLE:View.GONE);
}
public void addToWindow(){
wlp.flags=WindowManager.LayoutParams.FLAG_NOT_TOUCH_MODAL|WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE;
wlp.type=WindowManager.LayoutParams.TYPE_PHONE;
wlp.gravity=Gravity.LEFT|Gravity.TOP;
wlp.format=PixelFormat.RGBA_8888;
wlp.width=this.getLayoutParams().width;
wlp.height=this.getLayoutParams().height;
wlp.x=0;
wlp.y=DimensionUtil.getHeight(ctx);
wm.addView(this,wlp);
}
public void removeView(){
wm.removeView(this);
}
}
3：在activity中调用RocketView的显示浮点方法进行演示
RocketView rocketView=new RocketView(this.getApplicationContext()); rocketView.setLaunchView(new LaunchView(this.getApplicationContext())); rocketView.addToWindow();
4：总结
浮点的实现主要使用到android api的WindowManager，以及对WIndowManager.LayoutParams的一些参数的熟悉。
作者能力有限，特别是设计模式方面 不是很懂，希望高手多多指点
