支持任意view的平移缩放手势工具
github：GestureViewBinder 喜欢的记得给个star呦～有什么问题或者建议也希望能够指点一下，感激不尽！
使用时在app也就是根目录下的build.gradle中添加maven仓库地址
allprojects {
repositories {
...
maven { url 'https://jitpack.io' }
}
}然后在项目的build.grale中添加依赖
implementation 'com.github.GeniusLiu:GestureViewBinder:1.0.1'最后通过一行代码使用
GestureViewBinder.bind(this, groupView, targetView);如果你想让view充满group且大小不能小于group
gestureViewBinder.setFullGroup(true)
@Override protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) { setMeasuredDimension(3000, 3000); }
当设置view大小后，缩放中心点位置不对，希望可以有个解决的办法
public class OutLayout extends RelativeLayout {
private boolean mScrolling;
private float StartX, EndX;
private float StartY, EndY;
public OutLayout(Context context) {
this(context, null);
}
public OutLayout(Context context, AttributeSet attrs, int defStyleAttr) {
super(context, attrs, defStyleAttr);
}
public OutLayout(Context context, AttributeSet attrs) {
this(context, attrs, 0);
}
@Override
public boolean onInterceptTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
StartX = event.getX();
StartY = event.getY();
mScrolling = false;
break;
case MotionEvent.ACTION_MOVE:
if (Math.abs(StartX - event.getX()) >= ViewConfiguration.get(getContext()).getScaledTouchSlop() || Math.abs(StartY - event.getY()) >= ViewConfiguration.get(getContext()).getScaledTouchSlop()) {
mScrolling = true;
} else {
mScrolling = false;
}
break;
case MotionEvent.ACTION_UP:
mScrolling = false;
break;
}
return mScrolling;
}
@Override
public boolean onTouchEvent(MotionEvent event) {
switch (event.getAction()) {
case MotionEvent.ACTION_DOWN:
return true;
case MotionEvent.ACTION_MOVE:
break;
case MotionEvent.ACTION_UP:
EndX = event.getX();
EndY = event.getY();
if (StartX != EndX || StartY != EndY) {
view.isReturn = false;
} else {
view.isReturn = true;
}
break;
}
return super.onTouchEvent(event);
}
}
///////////------------------------------view 自己的事件 根据上面动态改变返回值
static boolean isReturn;
@Override
public boolean onTouchEvent(MotionEvent pMotionEvent) {
return isReturn;
}
需要实现一个unbind或者暂停bind的功能，而且现在1.0.1的引用没有作用，停止绘画开始缩放没效果
使用GestureViewBinder时用到的问题，父布局使用的RelativeLayout，子布局是自定义view，在自定义view中需要响应onTouchEvent事件的MotionEvent.ACTION_UP方法，这个要怎么处理？
能不能按照双指中间点缩放
