public abstract class BaseActivity extends AppCompatActivity {
    @Override
    protected void onCreate(@Nullable Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(getLayoutResId());
        //初始化view
        initView(savedInstanceState);
        //載入資料
        initData();
    }

    protected abstract void initData();

    protected abstract void initView(Bundle savedInstanceState);

    protected abstract int getLayoutResId();
}

 

1.2.fragment的基類

    }

    @Override
    public void onViewCreated(@NonNull View view, @Nullable Bundle savedInstanceState) {
        super.onViewCreated(view, savedInstanceState);
        //初始化view
        initView(view);

            urlConnection.setRequestMethod("GET");
            //設定超時
            urlConnection.setReadTimeout(5000);
            urlConnection.setConnectTimeout(5000);
            //獲取請求碼
            int responseCode = urlConnection.getResponseCode();
            if(responseCode==200){
                result = stream2String(urlConnection.getInputStream());
            }
        } catch (MalformedURLException e) {
            e.printStackTrace();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return result;
    }
    //將位元組流轉換為字元流
    private String stream2String(InputStream inputStream) throws IOException {
        StringBuilder builder = new StringBuilder();
        BufferedReader br = new BufferedReader(new InputStreamReader(inputStream));
        for (String tmp = br.readLine();tmp!=null;tmp=br.readLine()){
            builder.append(tmp);
        }
        return builder.toString();
    }
    //執行網路請求返回bean
    public <E> E getRequest(String urlStr,Class clazz){

        return (E) gson.fromJson(getRequest(urlStr),clazz);
    }
    //定義介面
    public interface CallBack<E>{
        void onSuccess(E e);
    }
    @SuppressLint("StaticFieldLeak")
    public void getRequest(String urlStr, final Class clazz, final CallBack callBack){
        new AsyncTask<String,Void,Object>(){
            @Override
            protected Object doInBackground(String... strings) {
                return getRequest(strings[0],clazz);
            }

            @Override
            protected void onPostExecute(Object o) {
                callBack.onSuccess(o);
            }
        }.execute(urlStr);
    }
}

3.二次取樣工具類

package com.example.zonghelianxi02.util;

import android.annotation.SuppressLint;
import android.graphics.Bitmap;
import android.graphics.BitmapFactory;
import android.os.AsyncTask;

public class BitmapUtil {
    private static BitmapUtil instance;

    public BitmapUtil() {
    }

    public static BitmapUtil getInstance() {
        if(instance==null){
            instance = new BitmapUtil();
        }
        return instance;
    }
    //二次取樣請求
    public Bitmap selectBitmap(String imagePath,int width,int height){
        //第一次只加載寬高資訊
        BitmapFactory.Options options = new BitmapFactory.Options();
        options.inJustDecodeBounds = true;
        BitmapFactory.decodeFile(imagePath,options);
        //根據原始寬高和請求寬高計算取樣lv
        options.inSampleSize = Math.max(options.outWidth/width,options.outHeight/height);
        //設定真正載入圖片
        options.inJustDecodeBounds = false;
        return BitmapFactory.decodeFile(imagePath,options);
    }
    //定義介面
    public interface CallBack{
        void onBitmap(Bitmap bitmap);
    }
    //回撥請求
    @SuppressLint("StaticFieldLeak")
    public void selectBitmap(String imagePath, final int width, final int height, final CallBack callBack){
        new AsyncTask<String,Void,Bitmap>(){
            @Override
            protected Bitmap doInBackground(String... strings) {
                return selectBitmap(strings[0],width,height);
            }
            @Override
            protected void onPostExecute(Bitmap bitmap) {
                callBack.onBitmap(bitmap);
            }
        }.execute(imagePath);
    }
}

4.二次取樣在values裡建一個dimens.xml

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <dimen name="leftIconSize">100dp</dimen>
</resources>

5.輪播圖小圓點

5.1預設圓點
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval"
    >
    <size
        android:width="8dp"
        android:height="8dp"
        />
    <solid
        android:color="#909090"
        />
</shape>

5.2選中圓點
<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval"
    >
    <size
        android:width="8dp"
        android:height="8dp"
        />
    <solid
        android:color="#900000"
        />
</shape>

5.3select
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/shape_sel_dot" android:state_selected="true"/>
    <item android:drawable="@drawable/shape_normal_dot"/>
</selector>

用到的bean類
1首頁bean

package com.example.zonghelianxi02.model;

import java.util.List;

public class HomeBean {

    private int code;
    private String msg;
    private List<NewslistBean> newslist;
    private final int SUCCESS_CODE=200;
    public boolean isSuccess(){
        return SUCCESS_CODE == code;
    }
    public int getCode() {
        return code;
    }

    public void setCode(int code) {
        this.code = code;
    }

    public String getMsg() {
        return msg;
    }

    public void setMsg(String msg) {
        this.msg = msg;
    }

    public List<NewslistBean> getNewslist() {
        return newslist;
    }

    public void setNewslist(List<NewslistBean> newslist) {
        this.newslist = newslist;
    }

    public static class NewslistBean {

        private String ctime;
        private String title;
        private String description;
        private String picUrl;
        private String url;

        public String getCtime() {
            return ctime;
        }

        public void setCtime(String ctime) {
            this.ctime = ctime;
        }

        public String getTitle() {
            return title;
        }

        public void setTitle(String title) {
            this.title = title;
        }

        public String getDescription() {
            return description;
        }

        public void setDescription(String description) {
            this.description = description;
        }

        public String getPicUrl() {
            return picUrl;
