我想合并两个android项目,一个是Main,另一个是Library.但是我在这方面遇到了一些麻烦:
Button modificarC;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
this.requestWindowFeature(Window.FEATURE_NO_TITLE);
setContentView(R.layout.activity_menu_calificaciones);
modificarC = (Button) findViewById(R.id.btn_aseso); //HERE
我尝试了Project Clean ...我的依赖项上也有android-support-v4.jar
这是我的追踪:
