如何在启动画面活动后打开fragement活动 [英] How to open fragement activity on after splash screen activity

问题描述

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：



< pre lang =java> 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.widget.ImageView;
public class SplashScreen extends AppCompatActivity {
    public MediaPlayer mp;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
       try {
//           getSupportActionBar().hide();

//           getWindow().setFlags(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.
