我要评论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：
