本文介绍了如何在启动画面活动后打开fragement活动的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述 29岁程序员，3月因学历无情被辞！ Hello Guys，我想知道如何在启动画面活动后打开片段活动，在启动画面中我在启动画面中使用动画请帮助我如何打开它。 提前致谢。 我的尝试： package com.complainprotectioncell; import android.content.Intent; import android.media.MediaPlayer; import android.os.Bundle; import android.support.v7.app.AppCompatActivity; import android.util.Log; import android.view.animation.Animation; import android.view.animation.AnimationUtils; import android.widget.ImageView; public class SplashScreen extends AppCompatActivity { public MediaPlayer mp; @ Override protected void onCreate（Bundle savedInstanceState）{ super .onCreate（savedInstanceState）; 尝试 { // getSupportActionBar（）。hide（）; // requestWindowFeature（Window.FEATURE_NO_TITLE）; // getWindow（）。setFlags（WindowManager.LayoutParams.FLAG_FULLSCREEN， // WindowManager.LayoutParams.FLAG_FULLSCREEN）; setContentView（R.layout。 front_splash_screen）; mp = MediaPlayer.create（ this ，R.raw.bgr_be_happy）; mp.start（）; startAnimation（）; } catch （例外情况） { Log.e（ 异常， 找到1 + ex）; } } public void startAnimation（ ） { 尝试 { final ImageView imageView =（ImageView ）findViewById（R.id.imageView）; final 动画animation_1 = AnimationUtils.loadAnimation（getBaseContext（），R.anim.rotate）; final 动画animation_2 = AnimationUtils.loadAnimation（getBaseContext（），R.anim.antirotate）; final 动画animation_3 = AnimationUtils.loadAnimation（getBaseContext（），R.anim.abc_fade_out）; imageView.startAnimation（animation_2）; animation_2.setAnimationListener（ new Animation.AnimationListener（）{ @ Override public void onAnimationStart（动画动画）{ } @覆盖 public void onAnimationEnd（动画动画）{ imageView.startAnimation（animation_1）; } @ Override public void onAnimationRepeat（动画动画）{ } }）; animation_1.setAnimationListener（ new Animation.AnimationListener（）{ @ Override public void onAnimationStart（动画动画）{ } @覆盖 public void onAnimationEnd（动画动画）{ 尝试 { startActivity（ new Intent（getApplicationContext（），Login。 class ））; finish（）; // imageView.startAnimation（animation_3）; // mp.release（）; } catch （Exception ex）{ Log.e（ Exception Splash，ex + ）; // Toast.makeText（SplashScreen.this，抱歉，事情变得错了，Toast.LENGTH_SHORT） .show（）; } } @覆盖 public void onAnimationRepeat（动画动画）{ } }）; } catch （例外情况） { Log.e（ 异常， 找到2）; } } @覆盖 protected void onStop（）{ super .onStop（）; 尝试 { if （mp！= null&& mp。 isPlaying（））{ mp.stop（）; mp.release（）; mp = null; } } catch （例外情况） { Log.e（ 发现异常，ex + ）; } } } 解决方案 我采用了一种与众不同的方法我的一个应用程序，因为它应该立即就绪，甚至在布局膨胀之前。因此，我没有使用布局，而是将启动画面的背景指定为活动的主题背景。 因此，我在 AndroidManifest.xml中将主要活动更改为 SplashActivity 文件，如： < activity android：name =。MainActivity android：label =@ string / app_name android：theme =@ style / AppTheme.NoActionBar> < / activity> < activity android：name =。SplashActivity android：theme =@ style / SplashTheme> < intent-filter> < action android：name =android.intent.action.MAIN/> < category android：name =android.intent.category.LAUNCHER/> < / intent-filter> < / activity> SplashActivity 的背景/主题如下： < style name =SplashThemeparent =Theme.AppCompat.NoActionBar> < item name =android：windowBackground> @ drawable / background_splash< / item> < / style> ... <？xml version =1.0encoding =utf-8？> < layer-list xmlns：android =http://schemas.android.com/apk/res/android> < item android：drawable =@ color / grey/> < item> < bitmap android：gravity =centerandroid：src =@ mipmap / ic_launcher/> < / item> < / layer-list> SplashActivity 类看起来像： 公共类SplashActivity扩展AppCompatActivity { @Override protected void onCreate（Bundle savedInstanceState） { super.onCreate（savedInstanceState）; Intent intent = new Intent（this，MainActivity.class）; startActivity（intent）; 完成（）; } } 然后在 MainActivity 中，按照您的意愿做任何事情。可能不是你想要的，但这也是谷歌现在这样做的方式。 Hello Guys, I want to know how can I open my fragment activity after splash screen activity and in my splash screen I am using animation in my splash screen please help me how can I open it.Thanks in Advance.What I have tried:package com.complainprotectioncell;import android.content.Intent;import android.media.MediaPlayer;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.util.Log;import android.view.animation.Animation;import android.view.animation.AnimationUtils;import android.widget.ImageView;public class SplashScreen extends AppCompatActivity { public MediaPlayer mp; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); try {// getSupportActionBar().hide();// requestWindowFeature(Window.FEATURE_NO_TITLE);// getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,// WindowManager.LayoutParams.FLAG_FULLSCREEN); setContentView(R.layout.front_splash_screen); mp = MediaPlayer.create(this, R.raw.bgr_be_happy); mp.start(); startAnimation(); }catch(Exception ex) { Log.e("Exception" , "Found 1" + ex); } } public void startAnimation() {try { final ImageView imageView = (ImageView) findViewById(R.id.imageView); final Animation animation_1 = AnimationUtils.loadAnimation(getBaseContext(), R.anim.rotate); final Animation animation_2 = AnimationUtils.loadAnimation(getBaseContext(), R.anim.antirotate); final Animation animation_3 = AnimationUtils.loadAnimation(getBaseContext(), R.anim.abc_fade_out); imageView.startAnimation(animation_2); animation_2.setAnimationListener(new Animation.AnimationListener() { @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { imageView.startAnimation(animation_1); } @Override public void onAnimationRepeat(Animation animation) { } }); animation_1.setAnimationListener(new Animation.AnimationListener() { @Override public void onAnimationStart(Animation animation) { } @Override public void onAnimationEnd(Animation animation) { try { startActivity(new Intent(getApplicationContext(), Login.class)); finish(); //imageView.startAnimation(animation_3); //mp.release(); } catch (Exception ex) { Log.e("Exception Splash", ex + "");// Toast.makeText(SplashScreen.this, "Sorry, Something went Wrong", Toast.LENGTH_SHORT).show(); } } @Override public void onAnimationRepeat(Animation animation) { } });}catch(Exception ex){ Log.e("Exception" , "Found 2");} } @Override protected void onStop() { super.onStop(); try { if (mp != null && mp.isPlaying()) { mp.stop(); mp.release(); mp = null; } }catch(Exception ex) { Log.e("Exception Found", ex + ""); } }} 解决方案 I took a far different approach with a splash screen for one of my apps because it should be ready immediately, even before a layout is inflated. So instead of using a layout, I specified the splash screen's background as the activity's theme background.So, I changed the main activity to be SplashActivity in the AndroidManifest.xml file, like:<activity android:name=".MainActivity" android:label="@string/app_name" android:theme="@style/AppTheme.NoActionBar"></activity><activity android:name=".SplashActivity" android:theme="@style/SplashTheme" > <intent-filter> <action android:name="android.intent.action.MAIN" /> <category android:name="android.intent.category.LAUNCHER" /> </intent-filter></activity>The background/theme for the SplashActivity looks like:<style name="SplashTheme" parent="Theme.AppCompat.NoActionBar"> <item name="android:windowBackground">@drawable/background_splash</item></style>...<?xml version="1.0" encoding="utf-8"?><layer-list xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@color/gray"/> <item> <bitmap android:gravity="center" android:src="@mipmap/ic_launcher"/> </item></layer-list>The SplashActivity class then looks like:public class SplashActivity extends AppCompatActivity{ @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); Intent intent = new Intent(this, MainActivity.class); startActivity(intent); finish(); }}Then in MainActivity, do whatever you want as normal. May not be exactly what you are looking for, but it is the way Google is doing this now, too. 这篇关于如何在启动画面活动后打开fragement活动的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持！ 上岸，阿里云！
