如何触摸特定现在的位置在图像视图 [英] How to touch the specific postion in the image view
问题描述
我在AppKISS ME，其中当用户触摸的背景图像左侧，在那里他接触到形象背后的嘴唇贴合工作....我想，只要用户触摸以外的图像女孩的脸上，贴显示不出来...粘贴只显示在脸上我怎么能只为脸部做？请帮助我，我用Google搜索，但没有找到任何东西。

您需要重新present图像作为几何形的脸，如方形或圆形。假设你重新presented它作为中心的圆（C1，C2）和半径r。现在每次用户触摸的ImageView，你会得到触摸点的X和Y。你计算之间（C1，C2）和（x，y）的距离。如果该距离大于r则用户触摸的点的圆外，面对外的意思。如果该距离小于r，则用户触摸了面部内，则显示的糊状物。
如果你看看图片，脸再由具有在中心的黄圈psented $ P $（XC，YC）和半径r。现在说用户触摸的点触摸1（XT，YT）的ImageView的。你计算（XC，YC）和（XT，YT）之间的距离。如果该距离大于半径r大于所述触摸是外循环，因此面外。另一方面，如果用户触摸在点触摸2.距离将小于面部内的半径，以便
两个点（X1，Y1）和（X2，Y2）之间距离计算公式为： sqroot（（X2-X1）^ 2 +（Y2-Y1）^ 2）
希望这有助于。让我知道如果你有任何问题。
I am working on the App "KISS ME" , in which when a user touch the background image a paste of the lips left behind where he touches the image .... I want that whenever a user touches the image other than the face of the girl , the paste don't show up ...Paste only shows on the face how can i do it only for the face??? Kindly help me out i have googled it but couldn't find anything
Here is my Main.java
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);

spool.setOnLoadCompleteListener(new OnLoadCompleteListener() {
@Override
public void onLoadComplete(SoundPool soundPool, int sampleId,
int status) {
Log.i("OnLoadCompleteListener", "Sound " + sampleId
+ " loaded.");
boolean loaded = true;
}
});
linearLayout.setOnTouchListener(this);
}
@Override

You need to represent the face in the image as a geometric shape such as a square or a circle. Say you represented it as a circle with center (c1,c2) and radius r. Now everytime the user touches the imageView, you will get the x and y of the touch point. You calculate the distance between (c1,c2) and (x,y). If the distance is greater than r then the user touched a point outside the circle, meaning outside the face. If the distance was less than r, then the user touch was inside the face, then you show up the paste.
If you look at the picture, the face is represented by the yellow circle that has a center at (xc, yc) and a radius r. Say now the user touches the ImageView at the point Touch 1 (xt,yt). You calculate the distance between (xc, yc) and (xt, yt). If the distance is greater than the radius r then the touch was outside the circle, so outside the face. On the other hand, if user touches at point Touch 2. The distance will be less than the radius so inside the face.
Distance formula between two points (x1,y1) and (x2,y2) is: sqroot((x2−x1)^2+(y2−y1)^2)
Hope this helps. Let me know if you have any questions.
