根目录下新建一个类继承application,调用xUtils3初始化方法 public class AtguiguApplication extends Application { @Override public void onCreate() { super.onCreate(); //xUtils3初始化 x.Ext.init(this); // 是否输出debug日志, 开启debug会影响性能. x.Ext.setDebug(true); } } manifest配置application name <application android:name=".AtguiguApplication"
@ContentView(R.layout.activity_xutils3_main) public class XUtils3MainActivity extends Activity { @ViewInject(R.id.tv_title) private TextView textView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // setContentView(R.layout.activity_xutils3_main); // x.view().inject(XUtils3MainActivity.this); x.view().inject(this); //设置标题 textView.setText("xUtils3的使用"); } @Event(value = {R.id.btn_annotation,R.id.btn_net,R.id.btn_image,R.id.btn_image_list}) private void getEvent(View view){ switch (view.getId()){ case R.id.btn_annotation: // Toast.makeText(XUtils3MainActivity.this, "注解模块被点击了", Toast.LENGTH_SHORT).show(); Intent intent = new Intent(XUtils3MainActivity.this, FragmentXUtils3Activity.class); startActivity(intent); break; case R.id.btn_net: Toast.makeText(XUtils3MainActivity.this, "网络模块被点击了", Toast.LENGTH_SHORT).show(); break; case R.id.btn_image: Toast.makeText(XUtils3MainActivity.this, "加载单张图片被点击了", Toast.LENGTH_SHORT).show(); break; case R.id.btn_image_list: Toast.makeText(XUtils3MainActivity.this, "加载列表图片被点击了", Toast.LENGTH_SHORT).show(); break; } } }
@ContentView(R.layout.activity_xutils3_fragment) public class FragmentXUtils3Activity extends FragmentActivity { @ViewInject(R.id.tv_title) private TextView textView; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // setContentView(R.layout.activity_xutils3_fragment); x.view().inject(this); textView.setText("在Fragment中使用注解"); //1.得到FragmentManger FragmentManager fm = getSupportFragmentManager(); //2.开启事务 FragmentTransaction tt = fm.beginTransaction(); //3.替换Fragment tt.replace(R.id.fl_content,new DemoFragment()); //4.提交 tt.commit(); } }
