android項目實戰(zhàn)-多媒體開發(fā)shhmvmplayer播放器

yer該項目采用的是MVPv層和p層的解耦使用目前比較流行的2、Ssh歡迎界面的完界面需求分析：1全屏2執(zhí)行縮放動畫3設(shè)置動畫，執(zhí)行動畫完畢界面跳1<stylename="AppTheme.FullScreen"<item2fromXScale,fromYScaleX,Y的縮放，0.01.0 動畫最終縮放的倍數(shù)，1.01.0 兩個都為3設(shè)置動畫，執(zhí)行動畫完畢界面跳animation.setAnimationListener(newAnimation.AnimationListener(){publicvoidonAnimationStart(Animationanimation)}publicvoidonAnimationEnd(Animationanimation)startActivity(newIntent(S}publicvoidonAnimationRepeat(Animationanimation)}UI4.4以下版本、4.4、5.0以上版本，創(chuàng)建：values-v19,values-<stylename="AppTheme" <stylename="AppTheme" <item<item<stylename="AppTheme" <item<item<!--Android5.x<item1compile'com.roughike:bottom- app:bb_tabXmlResource="@xml/bottombar_tabs" 被選中的Tab的顏色 Tab切換時的動畫效果 未被選中的Tab的 未被選中的Tab的顏色 加載對應(yīng)的Tab資源2Bottombartab條目點擊publicvoidonTabSelected(@IdResinttabId)//tabIdFragmentFragmentfragment}1主要是對數(shù)據(jù)的緩存進行處理（框架才用Glide）newThread(newRunnable(){publicvoidrun()}2時不會發(fā)送給該用戶（適用于支持用戶登錄）3Wifi下加載網(wǎng)絡(luò)NetworkInfomobNetInfoActivity=connectivityManager.getActiveNetworkInfo();intnetType=mobNetInfoActivity.getType();returnnetType== 1styles中創(chuàng)建繼承自@android:style/Animation.ActivityStyle<stylename="ActivityAnimations"<item2、在對應(yīng)的樣式中配置windowAnimationStyle屬<item1aptprojectgradle//Addpluginbuildscript{dependenciesclasspath'com.neenbedankt.gradle.plugins:android-}}2、aptmodlegradle//Applyapplyplugin:'com.neenbedankt.android-3dagger2//AddDaggerdependenciesdependencies{compile'com.apt'com.} 1Type{Typesuperclass=subclass.getGenericSuperclass();if(superclassinstanceofClass){thrownewRuntimeException("Missingtype}return}public{type=}2ItHeiMaHttpheiMaHttpItHeiMaHttp.getInstance().addHead("參數(shù)名稱","參數(shù)").//加頭addParam("參數(shù)名稱參數(shù)WSCallBack<Bean>JSON,StringheiMaHttp.get("BASE_URL",newWSCallBack<Bean>(){publicvoidonFailure(Callcall,Exceptione)//}publicvoidonSuccess(Beanbean)//}1HttpManagerhttpManager=addParam("offset",offset+"").addParam("size",size+"");publicvoidonFailure(Callcall,Exceptione){}publicvoidonSuccess(List<Bean>Been){}2Bean中的TypeIconfinalinttag;Stringtype=ifACTIVITY".equalsIgnoreCase(type)打開頁面tag=0;}elseif(" tag=1;

app:tabSelectedTextColor="@android:color/white"http://tab被選的文本顏色 //tab沒有被選的文本顏色app:tabMode="scrollable"設(shè)置可以滑動 2、根據(jù)獲取到的數(shù)據(jù)初始化Vie ge的Adpaterfor(inti=0;i<data.size();i++){}3 05、”MV”ITEM1、MV中的Vie ger的條目都是Fragment的形式，在Fragment中要根據(jù)對應(yīng)的code獲取對應(yīng)的類型數(shù)據(jù)，所以在Fragment初始化的時候就傳入對應(yīng)的codepublicstaticMvItemFragmentgetInstance(Stringcode)MvItemFragmentmvItemFragment=newMvItemFragment();Bundlebundle=newBundle();returnmvItemFragment;}//獲取codepublicvoidonCreate(@NullableBundlesavedInstanceState){code=(String)}//根據(jù)codepublicvoidgetData(Stringcode,intoffset,intsize)addParam("area",code).addParam("offset",""+offset).addParam("size",""+size);publicvoidonFailure(Callcall,Exceptione)}publicvoidonSuccess(MvItemBeanmvItemBean)}}06、”MV”ITEM//publicvoidonRefresh(){}//加載publicvoidonScrolled(RecyclerViewrecyclerView,intdx,intdy)}框和加載框才用比較火的compile 12、用戶按下返回publicvoidonBackPressed(){}super.onBackPressed();4、顯示finalMaterialDialog.Builderbuilder=newpublicvoidonClick(@NonNullMaterialDialogdialog,@NonNullDialogActionwhich){}publicvoidonClick(@NonNullMaterialDialogdialog,@NonNullDialogAction{}1Fragment//publicvoidshowDialog()MaterialDialog.Builderbuilder=newMaterialDialog.Builder(getActivity());gress(true,0);}//publicvoidif(dialog!=}MainActivitydispatchTouchEventcaselastY=ev.getRawY();floatmoveX=ev.getRawX();floatmoveY=ev.getRawY();offsetX=moveX-lastX;offsetY=moveY-floatintposition=if(absY>absX&&offsetY>10&&!isShowBottomBar&&//BottomBar}elseif(absY>absX&&offsetY<-10&&isShowBottomBar&&//BottomBar}2//privatevoidenterBottomBar(){isShowBottomBar=true;ObjectAnimatoroa=ObjectAnimator.ofFloat(bottomBar,"translationY",((float)bottomBar.getHeight()),0f);}//isShowBottomBar=ObjectAnimatoroa=ObjectAnimator.ofFloat(bottomBar,"translationY",0f,((float)}1RecyclerViewz StaggeredGridLayoutManager(2,StaggeredGridLayoutManager.VERTICAL);2、處理在滾動時移位的問 int1、條目點擊的處publicvoidonClick(Viewv)IntentmIntent=newIntent();switch(tag){casecasecasecase1:casecasecase2:case}} <item<solid<item//<item<solid器才用的是基于ijkyer的1、引入相應(yīng)的器23、根據(jù)Id獲取資源信息并通過器04MVPP1Dagger2實現(xiàn)層與層之間的2publicvoidquery(Contextcontext,MyCursorAdaptercursorAdapter)Uriuri=MediaStore.Audio.Media.MediaStore.Audio.Media.DURATION,MyQueryHandlermyQueryHandler=new//token:}05、獲取SD卡的權(quán)1，判斷是否申請了SD卡的權(quán)PackageManager.PERMISSION_DENIED2,申請SDK卡的權(quán)ActivityFragmentz3，權(quán)限申請結(jié)果protectedvoid

mediayer.setDataSource(musicItem.path);media}catch(IOExceptione){}}、 mond方法中接收數(shù)publicint mand(Intentintent,intflags,intstartId){inttemp=intent.getIntExtra("currentMusic", ying()&¤tMusic==temp){notifyy();}elsecurrentMusic=musicList=//開始.music .}}return}//設(shè)置準備的 Mediayer.OnPreparedListener Mediayer.OnPreparedListener(){publicvoidonPrepared(Mediayermp){}//設(shè)置完成的
