Android仿微信activity滑动关闭效果

android仿微信activity滑动关闭功能

1.利用具体利用v4包下的slidingpanelayout实现透明的activity，代码如下：

baseactivity:
public class baseslidecloseactivity extends appcompatactivity implements
  slidingpanelayout.panelslidelistener {

 @override
 protected void oncreate(bundle savedinstancestate) {
  initslidebackclose();
  super.oncreate(savedinstancestate);
 }

 private void initslidebackclose() {
  if (issupportswipeback()) {
   slidingpanelayout slidingpanelayout = new slidingpanelayout(this);
   // 通过反射改变moverhangsize的值为0，
   // 这个moverhangsize值为菜单到右边屏幕的最短距离，
   // 默认是32dp，现在给它改成0
   try {
    field overhangsize = slidingpanelayout.class.getdeclaredfield("moverhangsize");
    overhangsize.setaccessible(true);
    overhangsize.set(slidingpanelayout, 0);
   } catch (exception e) {
    e.printstacktrace();
   }
   slidingpanelayout.setpanelslidelistener(this);
   slidingpanelayout.setsliderfadecolor(getresources()
     .getcolor(android.r.color.transparent));

   // 左侧的透明视图
   view leftview = new view(this);
   leftview.setlayoutparams(new viewgroup.layoutparams(viewgroup.layoutparams.match_parent, viewgroup.layoutparams.match_parent));
   slidingpanelayout.addview(leftview, 0);

   viewgroup decorview = (viewgroup) getwindow().getdecorview();


   // 右侧的内容视图
   viewgroup decorchild = (viewgroup) decorview.getchildat(0);
   decorchild.setbackgroundcolor(getresources()
     .getcolor(android.r.color.white));
   decorview.removeview(decorchild);
   decorview.addview(slidingpanelayout);

   // 为 slidingpanelayout 添加内容视图
   slidingpanelayout.addview(decorchild, 1);
  }
 }

 protected boolean issupportswipeback() {
  return true;
 }

 @override
 public void onpanelslide(view panel, float slideoffset) {

 }

 @override
 public void onpanelopened(view panel) {
  finish();
 }

 @override
 public void onpanelclosed(view panel) {

 }
}

activity 透明style：
