管理Fragment的框架Fragmentation

1.fragment的出现本来是为了解决android适配的，但是如果使用Fragment开发app可以使软件更流畅

但是fragment的管理比较麻烦，个人建议使用Fragmentation框架对Fragment进行统一管理

1.所有的Fragment都要集成SurpportFragment

public abstract class BaseFragment extends SupportFragment {
    private BaseActivity mActivity;

    @Override
    public void onAttach(Context context) {
        super.onAttach(context);
        mActivity= (BaseActivity) context;
    }
    @Override
    public void onDetach() {
        super.onDetach();
        mActivity=null;
    }
    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
        View view=inflater.inflate(getLayoutId(),container,false);
        return view;
    }

    @Override
    public void onViewCreated(View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        init(view);
    }

    @Override
    public void onActivityCreated(@Nullable Bundle savedInstanceState) {
        super.onActivityCreated(savedInstanceState);
        initData(savedInstanceState);
    }
    protected abstract int getLayoutId();

    protected abstract void init(View view);

    protected abstract void initData(Bundle savedInstanceState);

2.所有的Activity都要继承SurpportActivity

/**

 * email:[email protected]
 */
public abstract class BaseActivity extends SupportActivity {
    @Override
    public void onCreate( Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(getLayoutId());
        initView();
        initData(savedInstanceState);
    }

    protected abstract void initData(Bundle savedInstanceState);

    protected abstract void initView();

    protected abstract int getLayoutId();

    //写一个全局的跳转
    public  void openActivityWithIntent(@NonNull Class activity,@NonNull Bundle bundle){
        Intent intent=new Intent(this,activity);
        if (bundle!=null) {
            intent.putExtras(bundle);
        }
        startActivity(intent);
    }
    public Bundle getIntentBundle(){
        Bundle bundle = getIntent().getExtras();
        return bundle;
    }
}

3.在Acitivity调用Fragment
 

public class MainActivity extends BaseActivity implements View.OnClickListener {

    private ImageView mAppIvTabMain;
    /**
     * 首页
     */
    private TextView mAppTvTabMain;
    private RelativeLayout mAppRlTabMain;
    private ImageView mAppIvTabBeauty;
    /**
     * 美女
     */
    private TextView mAppTvTabBeauty;
    private RelativeLayout mAppRlTabBeauty;
    private ImageView mAppIvTabFunction;
    /**
     * 功能
     */
    private TextView mAppTvTabFunction;
    private RelativeLayout mAppRlTabFunction;
    private ImageView mAppIvTabVideo;
    /**
     * 消息
     */
    private TextView mAppTvTabVideo;
    private RelativeLayout mAppRlTabVideo;
    private ImageView mAppIvTabSetting;
    /**
     * 我的
     */
    private TextView mAppTvTabSetting;
    private RelativeLayout mAppRlTabSetting;
    private LinearLayout mLlBottom;
    //存储imageView和TextView的集合
    ImageView[] imageViews = new ImageView[5];
    TextView[] textViews = new TextView[5];

    @Override
    protected void initData(Bundle savedInstanceState) {
        if (savedInstanceState == null) {
            loadRootFragment(R.id.fl_container, HomeFragment.newInstance()); //activity初始加载HomeFragment
        }
    }

    @Override
    protected void initView() {
        mAppIvTabMain = (ImageView) findViewById(R.id.app_iv_tab_main);
        mAppTvTabMain = (TextView) findViewById(R.id.app_tv_tab_main);
        imageViews[0] = mAppIvTabMain;
        textViews[0] = mAppTvTabMain;
        mAppRlTabMain = (RelativeLayout) findViewById(R.id.app_rl_tab_main);
        mAppRlTabMain.setOnClickListener(this);
        mAppIvTabBeauty = (ImageView) findViewById(R.id.app_iv_tab_beauty);
        mAppTvTabBeauty = (TextView) findViewById(R.id.app_tv_tab_beauty);
        imageViews[1] = mAppIvTabBeauty;
        textViews[1] = mAppTvTabBeauty;
        mAppRlTabBeauty = (RelativeLayout) findViewById(R.id.app_rl_tab_beauty);
        mAppRlTabBeauty.setOnClickListener(this);
        mAppIvTabFunction = (ImageView) findViewById(R.id.app_iv_tab_function);
        mAppTvTabFunction = (TextView) findViewById(R.id.app_tv_tab_function);
        imageViews[2] = mAppIvTabFunction;
        textViews[2] = mAppTvTabFunction;
        mAppRlTabFunction = (RelativeLayout) findViewById(R.id.app_rl_tab_function);
        mAppRlTabFunction.setOnClickListener(this);
        mAppIvTabVideo = (ImageView) findViewById(R.id.app_iv_tab_video);
        mAppTvTabVideo = (TextView) findViewById(R.id.app_tv_tab_video);
        imageViews[3] = mAppIvTabVideo;
        textViews[3] = mAppTvTabVideo;
        mAppRlTabVideo = (RelativeLayout) findViewById(R.id.app_rl_tab_video);
        mAppRlTabVideo.setOnClickListener(this);
        mAppIvTabSetting = (ImageView) findViewById(R.id.app_iv_tab_setting);
        mAppTvTabSetting = (TextView) findViewById(R.id.app_tv_tab_setting);
        imageViews[4] = mAppIvTabSetting;
        textViews[4] = mAppTvTabSetting;
        mAppRlTabSetting = (RelativeLayout) findViewById(R.id.app_rl_tab_setting);
        mAppRlTabSetting.setOnClickListener(this);
        mLlBottom = (LinearLayout) findViewById(R.id.ll_bottom);

    }

    @Override
    protected int getLayoutId() {
        return R.layout.activity_main;
    }

    @Override
    public void onClick(View v) {
        switch (v.getId()) {
