android - 当尝试使用 addView 获取 : "Skipped 63 frames! The application may be doing too much work on its main thread" 添加 layoutinflater

Question

我正在尝试在 onItemSelected 时添加预制布局。线路有问题:

selectLayout.addView(v);

当我删除这段代码时，它正在运行。

这也是我所有的代码。

    }

</LinearLayout>

Answer 1

您的 LinearLayout id 是

 android:id="@+id/selectLayout"

但是你有这个

selectLayout = (LinearLayout) findViewById(R.id.saffet);

所以改成

selectLayout = (LinearLayout) findViewById(R.id.selectLayout);

The application may be doing too much work on its main thread.

您的主线程是 ui 线程。作为 commonsware 建议使用 traceview。您是否有其他 Activity 进行一些密集计算，因为我在 Select.java 中看不到很多计算。如果是这样，请使用 thread 或 asynctask。
