如何在Android Studio中设置关于页面库 [英] How to set the about page library in android studio

问题描述

我正在尝试使用

编译'com.github.medyo:android-about-page:1.0.2'

compile 'com.github.medyo:android-about-page:1.0.2'

但是我收到了我在github中给出的设置的运行时错误 这是我的Java代码:

But I am getting a run time error I have set as it is given in the github here is my java code:

import android.os.Bundle;
import android.support.v7.app.AppCompatActivity;
import android.view.View;
import mehdi.sakout.aboutpage.AboutPage;
import mehdi.sakout.aboutpage.Element;

public class MainActivity extends AppCompatActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Element versionElement = new Element();
    versionElement.setTitle("Version 6.2");

    Element adsElement = new Element();
    adsElement.setTitle("Advertise with us");

    View aboutPage = new AboutPage(this)
            .isRTL(false)
            .setImage(R.drawable.wall)
            .addItem(versionElement)
            .addItem(adsElement)
            .addGroup("Connect with us")
            .addEmail("[e-mail]")
            .addFacebook("the.medy")
            .addTwitter("medyo80")
            .addYoutube("UCdPQtdWIsg7_pi4mrRu46vA")
            .addPlayStore("com.ideashower.readitlater.pro")
            .addInstagram("medyo80")
            .addGitHub("medyo")
            .create();

    setContentView(aboutPage);
}

} 有人可以告诉我要对我的代码进行哪些更改以设置支持库.我正在尝试从 https://github.com/medyo/android-about-page 我已经同步了gradle. gradle文件

推荐答案

In order to use this Library you need to use jcenter.

As it defines Available on Jcenter, Maven and JitPack.

因此，如下所示修改您的Build.Gradle.

So modify your Build.Gradle as below.

apply plugin: 'com.android.application'

buildscript {
    repositories {
        jcenter()
    }
}

这是您需要使用的代码.

public class MainActivity extends AppCompatActivity {

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

        Element versionElement = new Element();
        versionElement.setTitle("Version 6.2");

        Element adsElement = new Element();
        adsElement.setTitle("Advertise with us");

        View aboutPage = new AboutPage(this)
                .isRTL(false)
                .setImage(R.drawable.dummy_image)
                .addItem(versionElement)
                .addItem(adsElement)
                .addGroup("Connect with us")
                .addEmail("[e-mail]")
                .addFacebook("the.medy")
                .addTwitter("medyo80")
                .addYoutube("UCdPQtdWIsg7_pi4mrRu46vA")
                .addPlayStore("com.ideashower.readitlater.pro")
                .addInstagram("medyo80")
                .addGitHub("medyo")
                .create();

        setContentView(aboutPage);
    }
}

注意:不需要setContentView(R.layout.activity_main)来编写代码，因为库是自动生成的.

Note: setContentView(R.layout.activity_main) is not Required to write in code because library Generating it Automatically.
