求高手解惑！

at lux.aust.android_sample_file2.MainActivity.onCreate(MainActivity.java:22) 你的MainActivity 22行包的错，看log应该是setContentView 把你的layout的代码贴出来看看，应该是layout离引用了一个应用不到的资源

怎么改啊

[Fuuqiu]

空指针异常?是不是没有注册activity或者控件引入错误

[-图-]

没找到资源文件 getResources().getAssets().open("test2.txt");

[dielianxian]

Debug 跟踪 tv1.setText(getFromRaw("test1.txt")); tv2.setText(getFromAsset("test2.txt")); 这两个方法里 方法体里应该获取到异常了

[踩屎3号]

setContentView之前没有加上这行代码：super.onCreate(savedInstanceState);

[叹了口丶气]

和你遇到一样的问题。。在空指针那个地方加个try catch 可以过
