整理一下appintro的简单用法

https://github.com/apl-devs/AppIntro/issues/264

在添加之前会出现这样的一个错误。

ArrayIndexOutOfBoundsException

需要删除的appintro的oncrate方法中的

PersistentBundle

remove PersistentBundle argument from your OnCreate method.

这是官网的教程。

@0 添加　根目录下的

allprojects {
    repositories {
        jcenter()

        maven { url 'https://jitpack.io' }
    }
}
app目录下的

dependencies {
    compile fileTree(dir: 'libs', include: ['*.jar'])
    testCompile 'junit:junit:4.12'
    compile 'com.android.support:appcompat-v7:25.3.1'

    compile 'com.github.apl-devs:appintro:v4.2.0'
}

@1 生成一个SampleSlide文件。https://github.com/apl-devs/AppIntro/blob/master/example/src/main/java/com/amqtech/opensource/appintroexample/util/SampleSlide.java

import android.os.Bundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;

public class SampleSlide extends Fragment {

    private static final String ARG_LAYOUT_RES_ID = "layoutResId";
    private int layoutResId;

    public static SampleSlide newInstance(int layoutResId) {
        SampleSlide sampleSlide = new SampleSlide();

        Bundle args = new Bundle();
        args.putInt(ARG_LAYOUT_RES_ID, layoutResId);
        sampleSlide.setArguments(args);

        return sampleSlide;
    }

    @Override
    public void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        if (getArguments() != null && getArguments().containsKey(ARG_LAYOUT_RES_ID)) {
            layoutResId = getArguments().getInt(ARG_LAYOUT_RES_ID);
        }
    }

    @Nullable
    @Override
    public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container,
                             @Nullable Bundle savedInstanceState) {
        return inflater.inflate(layoutResId, container, false);
    }
}

＠２新建一个引导页文件

import android.os.Bundle;
import android.os.PersistableBundle;
import android.support.annotation.Nullable;
import android.support.v4.app.Fragment;

import com.github.paolorotolo.appintro.AppIntro;

/**
 * Created by mt on 6/19/17.
 */
public class appintros extends AppIntro {

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        addSlide(SampleSlide.newInstance(R.layout.slideone));
        addSlide(SampleSlide.newInstance(R.layout.slidetwo));
        addSlide(SampleSlide.newInstance(R.layout.slidethree));

       // setFadeAnimation();

        setFlowAnimation();
       showSkipButton(false);
      //  showDoneButton(false);

        //showSkipButton(false);

    }


    @Override
    public void onSkipPressed(Fragment currentFragment) {
        super.onSkipPressed(currentFragment);
        //finish();
    }

    @Override
    public void onDonePressed(Fragment currentFragment) {
        super.onDonePressed(currentFragment);
        finish();
    }


    @Override
    public void onSlideChanged(@Nullable Fragment oldFragment, @Nullable Fragment newFragment) {
        super.onSlideChanged(oldFragment, newFragment);
       // finish();//这里需要注释掉

    }
}

并添加到配置文件中。

@3 主文件让引导页显示一次。

        Thread t = new Thread(new Runnable() {
            @Override
            public void run() {
                //  Initialize SharedPreferences
                SharedPreferences getPrefs = PreferenceManager
                        .getDefaultSharedPreferences(getBaseContext());

                //  Create a new boolean and preference and set it to true
                boolean isFirstStart = getPrefs.getBoolean("firstStart", true);

                //  If the activity has never started before...
                if (isFirstStart) {

                    //  Launch app intro
                    Intent intent = new Intent(MainActivity.this, appintros.class);
                    startActivity(intent);

                    //  Make a new preferences editor
                    SharedPreferences.Editor e = getPrefs.edit();

                    //  Edit preference to make it false because we don't want this to run again
                    e.putBoolean("firstStart", false);

                    //  Apply changes
                    e.apply();
                }
            }
        });

        // Start the thread
        t.start();

＠４j最后新建引导页布局文件即可。
