上篇文章有些小伙伴问我怎么去看布局文件的，我这里交代先我分析界面的方法
1、 adb shell dumpsys activity top

2、 as自带的layout inspector(有些情况无法得到绘制)

但是显示效果最好
3、 Android Device Monitor 相信以前用eclipse时候adt经常用到的

好了废话不多说了，以上是我用到的，如果有更好的可以给我留言。😁~
首先terminal输入adb shell dumpsys activity top 如下

往下继续翻

然后咱们看看分析分析SnsTimeLineUI里面的代码逻辑
public void onCreate(Bundle bundle) {
...省略N多代码...
this.skT = this.rUA;
this.slh.a(this.sle, this.jzz, str, str2, this.slf, this.rWo, this.slg);
//这句话是初始化里面的列表等组建
this.slh.onCreate();
ae.byE().init();
this.mActionBar = getSupportActionBar();
com.tencent.mm.kernel.g.Ea();
com.tencent.mm.kernel.g.DX().fUP.a((int) com.tencent.mm.plugin.appbrand.jsapi.bio.face.c.CTRL_INDEX, (e) this);
com.tencent.mm.kernel.g.Ea();
com.tencent.mm.kernel.g.DX().fUP.a(682, (e) this);
com.tencent.mm.kernel.g.Ea();
com.tencent.mm.kernel.g.DX().fUP.a(218, (e) this);
...省略N多代码...
}
通过上面的代码可以找到
com.tencent.mm.plugin.sns.ui.bb
在这个文件里面就有我们刚才在terminal里面看到的很多关联的东西

所以关联起来可以开始编码了,里面注释的代码都是打印的关键信息，可以在一边调试一边看输出信息
/**

* @param classLoader
*/
private void hookWxMoments(final Context applicationContext, final ClassLoader classLoader) throws Error {
XposedHelpers.findAndHookMethod("com.tencent.mm.plugin.sns.ui.bb",

XposedHelpers.findAndHookMethod(mlvSuperClass,

view.setOnLongClickListener(new View.OnLongClickListener() {

for (int i = 0; i < msgLinear.getChildCount(); i++) {

String resourceName = applicationContext.getResources().getResourceName(mc.getId());
if (mc instanceof TextView) {
// mc.setVisibility(View.VISIBLE);
// ((TextView) mc).append("看雪论坛，看雪论坛++，看雪论坛+++");
//因为有些gettext 得到的是spanned 调toString会引起shutdown 所以用以下方式打印即可
// LogUtils.i(((TextView) mc).getText());
} else if (mc instanceof ViewStub) {
// ((ViewStub) mc).inflate();
} else if("com.tencent.mm:id/de_".equals(resourceName)){
ViewGroup vg = (ViewGroup)mc;
mc.setVisibility(View.VISIBLE);
if(vg.getChildCount()>0){

}
// LogUtils.i(mc, resourceName, "com.tencent.mm:id/de_");

}

});
}
}).setNeutralButton("不是的", null).show();
return false;

}

最终结果 如下图

去掉注释我把所有view都展示出来了，后面过滤注释无用代码后只留下点赞栏目的view即可
这个只是做了ui效果，后面会进行数据库保存记录，保证下次浏览到该条信息能够直接显示点赞数据，并且尽可能实现从好友列表选择点赞人
