Banner的使用

首先第一步就是进行依赖包

这个是okhttp的依赖包

compile 'com.squareup.okio:okio:1.5.0'compile 'com.squareup.okhttp3:okhttp:3.2.0'compile 'com.squareup.okhttp3:logging-interceptor:3.4.1'

解析的时候的依赖包compile 'com.google.code.gson:gson:2.8.2'

banner的依赖包compile 'com.youth.banner:banner:1.4.9'

glide的依赖包
compile 'com.github.bumptech.glide:glide:3.7.0'

添加所需要的权限

<uses-permissio android:name="android.permission.INTERNET"></uses-permission>

<uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE"></uses-permission>

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"></uses-permission>

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>

添加utils工具包

添加布局文件

<com.youth.banner.Banner    xmlns:app="http://schemas.android.com/apk/res-auto"    android:id="@+id/banner"    android:layout_width="match_parent"    android:layout_height="150dp" />

添加activity的文件

public class MainActivity extends AppCompatActivity {    String  mpath="http://api.tianapi.com/social/?key=71e58b5b2f930eaf1f937407acde08fe&num=20";    private Banner banner;    private ArrayList<String> mlist;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main);        banner = (Banner) findViewById(R.id.banner);        mlist=new ArrayList<>();        boolean b = NetWorkUtils.isNetWorkAvailable(this);        if(!b){            Toast.makeText(MainActivity.this,"网络未连接",Toast.LENGTH_SHORT).show();        }        getDate();    }    private void getDate() {        OkHttp3Utils.getInstance().doGet(mpath, new GsonObjectCallback<NewWord>() {            @Override            public void onUi(NewWord newWord) {                for(int i=0; i<newWord.getNewslist().size();i++){                    String ad1s = newWord.getNewslist().get(i).getPicUrl();                    mlist.add(ad1s);                }                //设置图片加载器                banner.setImageLoader(new geLoader());                banner.setImages(mlist);                banner.start();            }            @Override            public void onFailed(Call call, IOException e) {            }        });    }    public class geLoader extends ImageLoader {        @Override        public void displayImage(Context context, Object path, ImageView imageView) {            Glide.with(context).load(path).into(imageView);        }    }
这样衣蛾简单的就做出来了
