老套路看下效果图：
上面是穿山甲的广告页面,需求是添加自定义布局到别人SDK的页面，SDK内部不支持这样方式。怎么办呢？
思路：实际上我们可以换位思考下，如果能拿到这个广告页的activity页面，在这个拿到的activity页面添加自定义布局不就好了。
看下如何获取当前activty:下面这个方法要在application中初始化
/**
* 监听Activity变化
*/
private void initActivityLifecycleCallbacks() {
registerActivityLifecycleCallbacks(new ActivityLifecycleCallbacks() {
@Override
public void onActivityCreated(Activity activity, Bundle savedInstanceState) {
//每次都添加activity到栈中
ActivityManager.getInstance().addActivity(activity);
Log.i("wsc", String.format("ActivityLifecycleCallbacks ---- onActivityCreated %s", activity.getLocalClassName()));
}
@Override
public void onActivityStarted(Activity activity) {
if (activityCount == 0) {
ActivityManager.getInstance().setAppInBackGround(false);
Log.i("wsc", String.format("ActivityLifecycleCallbacks ---- onActivityStarted 回到前台 %s ", activity.getLocalClassName()));
AppRecordUtils.getInstance().startRecord();
}
activityCount++;
Log.i("wsc", String.format("ActivityLifecycleCallbacks ---- onActivityStarted %s ", activity.getLocalClassName()));
}
@Override
public void onActivityResumed(Activity activity) {
Log.i("wsc", String.format("ActivityLifecycleCallbacks ---- onActivityResumed %s ", activity.getLocalClassName()));
}
@Override
public void onActivityPaused(Activity activity) {
Log.i("wsc", String.format("ActivityLifecycleCallbacks ---- onActivityPaused %s ", activity.getLocalClassName()));
}
@Override
public void onActivityStopped(Activity activity) {
activityCount--;
if (activityCount == 0) {
ActivityManager.getInstance().setAppInBackGround(true);
Log.i("wsc", String.format("ActivityLifecycleCallbacks ---- onActivityStopped app 在后台运行%s ", activity.getLocalClassName()));
AppRecordUtils.getInstance().stopRecord();
}
Log.i("wsc", String.format("ActivityLifecycleCallbacks ---- onActivityStopped %s ", activity.getLocalClassName()));
}
@Override
public void onActivitySaveInstanceState(Activity activity, Bundle outState) {
}
@Override
public void onActivityDestroyed(Activity activity) {
ActivityManager.getInstance().removeActivity(activity);
Log.i("wsc", String.format("ActivityLifecycleCallbacks ---- onActivityDestroyed %s ", activity.getLocalClassName()));
}
});
}看下自己写ActivityManager

将自定义布局添加到activity的方法：
new Handler().postDelayed(new Runnable() {
@Override
public void run() {
Log.i("kk", ActivityManager.getInstance().getCurrentActivity().getComponentName().getClassName() + "pppp");
addViewToContent(ActivityManager.getInstance().getCurrentActivity());
}
}, 300); public void addViewToContent(final Activity activity) {
if (activity == null) {
return;
}
activity.getWindow().getDecorView().post(new Runnable() {
@Override
public void run() {
FrameLayout frameLayout = (FrameLayout) activity.findViewById(Window.ID_ANDROID_CONTENT);
View addView = View.inflate(activity, R.layout.ad_page_add_view, null);
FrameLayout.LayoutParams layoutParams = new FrameLayout.LayoutParams(
FrameLayout.LayoutParams.WRAP_CONTENT,
RelativeLayout.LayoutParams.WRAP_CONTENT,
Gravity.RIGHT);
layoutParams.topMargin = CommonUtil.dip2px(activity,80);
addView.setLayoutParams(layoutParams);
frameLayout.addView(addView);
}
});
}看下xml布局：
