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
/** * Author:DoctorWei * Time:2018/11/3 11:16 * Description:基类Fragment * email:[email protected] */ 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
/** * Author:DoctorWei * Time:2018/11/2 18:33 * Description:定义一个Activity的基类 用于加载 * 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()) {
default:
break;
case R.id.app_rl_tab_main:
HomeFragment homeFragment=findFragment(HomeFragment.class);
Bundle newBundle=new Bundle();
newBundle.putString(Extra.FRAGMENT_FROM,"主页来自:"+getTopFragment().getClass());
start(homeFragment, SupportFragment.SINGLETASK);
break;

popTo(HomeFragment.class, false, new Runnable() {

}
break;

popTo(FunctionFragment.class, false, new Runnable() {

}else{

}
break;
case R.id.app_rl_tab_video://消息
MessageFragment messageFragment=findFragment(MessageFragment.class);

popTo(MessageFragment.class, false, new Runnable() {

});
}else{
start(messageFragment,SupportFragment.SINGLETASK);
}
break;
