如何使用android-support-v7-appcompat

天真的以为跟v4一样，把jar包放入自个儿的项目即可，不出各位看官所料，报错了，喜欢看官方的可以看这里 support library setup

当直接把jar包放入，错误信息如下：

其实错误信息中很赤裸裸的告诉咱了，缺style，关键是为什么会缺呢？

java.lang.NoClassDefFoundError: android.support.v7.appcompat.R$styleable

其实v7中有大量的style，也就是说简单添加jar包并没有引入style，所以只能以library的形式添加到自个儿的项目中，步骤如下：



选择自己SDK下的sdk/extras/android/support/v7/appcompat，导入项目，记得勾选


然后在自己的项目中操作如下，注意红框部分：



然后点击绿色部分，添加v4,v7的jar包：



然后：



没记错的话，应该大功告成了，下课~
