BaseActivity
public abstract class BaseActivity extends AppCompatActivity implements View.OnClickListener,ViewPager.OnPageChangeListener,RadioGroup.OnCheckedChangeListener{ @Override protected void onCreate(@Nullable Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(getLayoutId()); findId(); initData(); } /** * 获取布局的id * @return */ protected abstract int getLayoutId(); /** * 找到控件的id */ protected abstract void findId(); /** * 初始化数据的操作 */ protected abstract void initData();}封装完成之后，创建一个activity继承baseActivity，并重写里面的方法
public class SecondActivity extends BaseActivity { private Button button; private Button button_02; private RadioGroup radioGroup; /** * 关联当前activity显示的布局的id * @return */ @Override protected int getLayoutId() { return R.layout.second_layout; } /** * 找到当前activity上面的控件 */ @Override protected void findId() { button = (Button) findViewById(R.id.button_01); button_02 = (Button) findViewById(R.id.button_02); radioGroup = (RadioGroup) findViewById(R.id.radio_group); } /** * 有关数据有关逻辑的操作写在这里面 */ @Override protected void initData() { //设置点击事件 button.setOnClickListener(this); button_02.setOnClickListener(this); //radioGroup监听 radioGroup.setOnCheckedChangeListener(this); } /** * radioGroup的事件 * @param radioGroup * @param i */ @Override public void onCheckedChanged(RadioGroup radioGroup, int i) { switch (i){ } } @Override public void onClick(View view) { switch (view.getId()){ case R.id.button_01: break; case R.id.button_02: break; } } @Override public void onPageScrolled(int position, float positionOffset, int positionOffsetPixels) { } @Override public void onPageSelected(int position) { } @Override public void onPageScrollStateChanged(int state) { }}BaseFragment
public abstract class BaseFragment extends Fragment implements View.OnClickListener{ @Nullable @Override public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) { View view = initView(inflater,container); return view; } /** * 关联布局,,,并且找到控件id的操作 * @param inflater * @param container * @return */ protected abstract View initView(LayoutInflater inflater, ViewGroup container); @Override public void onActivityCreated(@Nullable Bundle savedInstanceState) { super.onActivityCreated(savedInstanceState); //逻辑的操作 initData(); } protected abstract void initData();}封装完成之后，创建一个fragment继承封装的basefragment，重写里面的方法
public class FragmnetNews extends BaseFragment { @Override protected View initView(LayoutInflater inflater, ViewGroup container) { View view = inflater.inflate(R.layout.second_layout,container,false); //找到id return view; } @Override protected void initData() { //获取数据 //设置适配器 } @Override public void onClick(View view) { }}封装json方法
在解析的时候调用
public class JsonUtil { public static Gson gson = new Gson(); /** * DataDataBean dataDataBean = gson.fromJson(s,DataDataBean.class); * * 这一一种解析数据的格式,,,{}对应,解析出来是一个实体类对象 */ public static <T> T parseJson(String json,Class<T> tClass){ T t = gson.fromJson(json, tClass); return t; } /** * List<DataDataBean> listData = gson.fromJson(s,type); * * 这是第二种,解析出来是一个list集合 */}
