Volley，Glide，Swiperefreshlayout 简单使用

1. AndroidManifest.xml 添加网络权限

    <uses-permission android:name="android.permission.INTERNET" />
     <!--usesCleartextTraffic 使用明文网络流量 不添加 API 28或更高级别的应用会报错-->
    <application android:usesCleartextTraffic="true">

2. build.gradle 添加引用库

dependencies {
     //HTTP 请求
    implementation 'com.android.volley:volley:1.2.1'
    //加载网络图片
    implementation 'com.github.bumptech.glide:glide:4.13.2'
    annotationProcessor 'com.github.bumptech.glide:compiler:4.13.2'
    //上拉刷新下拉加载
    implementation "androidx.swiperefreshlayout:swiperefreshlayout:1.1.0"
}

3. Volley 的使用请求文本

  3.1 布局文件 activty_main.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">
    <ScrollView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        app:layout_constraintBottom_toBottomOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintTop_toTopOf="parent">

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            android:orientation="vertical" >

            <TextView
                android:id="@+id/textView"
                android:layout_width="match_parent"
                android:layout_height="wrap_content"
                android:text="TextView"
                android:textSize="16sp" />
        </LinearLayout>
    </ScrollView>
</androidx.constraintlayout.widget.ConstraintLayout>

  3.2 测试方法

    //Volley 请求文本
    private void stringRequest() {
        String url = "http://www.baidu.com";
        //String url = "https://pixabay.com/api/?key=30070990-cfc31c9f778ceeef4009d910d&q=yellow+flowers&image_type=photo";
        TextView textView = findViewById(R.id.textView);
        RequestQueue queue = Volley.newRequestQueue(this);
        StringRequest stringRequest = new StringRequest(Request.Method.GET, url, new Response.Listener<String>() {
            @Override
            public void onResponse(String response) {
                Log.e(TAG, response);
                textView.setText(response);
            }
        }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {
                Log.e(TAG, "onErrorResponse", error);
            }
        });
        queue.add(stringRequest);
    }

4. Volley 的使用请求显示图片

  4.1 布局文件 activity_image.xml

<?xml version="1.0" encoding="utf-8"?>
<androidx.swiperefreshlayout.widget.SwipeRefreshLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/swipeRefreshLayout"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <androidx.constraintlayout.widget.ConstraintLayout
        android:layout_width="match_parent"
        android:layout_height="match_parent">

        <ImageView
            android:id="@+id/imageView"
            android:layout_width="0dp"
            android:layout_height="160dp"
            app:layout_constraintBottom_toTopOf="@+id/imageView2"
            app:layout_constraintEnd_toEndOf="@+id/imageView2"
            app:layout_constraintStart_toStartOf="@+id/imageView2"
            app:layout_constraintTop_toTopOf="parent"
            tools:srcCompat="@tools:sample/avatars" />

        <com.android.volley.toolbox.NetworkImageView
            android:id="@+id/imageView2"
            android:layout_width="0dp"
            android:layout_height="160dp"
            app:layout_constraintBottom_toTopOf="@+id/imageView3"
            app:layout_constraintEnd_toEndOf="@+id/imageView3"
            app:layout_constraintStart_toStartOf="@+id/imageView3"
            app:layout_constraintTop_toBottomOf="@+id/imageView"
            tools:srcCompat="@tools:sample/avatars" />

        <ImageView
            android:id="@+id/imageView3"
            android:layout_width="0dp"
            android:layout_height="160dp"
            app:layout_constraintBottom_toBottomOf="parent"
            app:layout_constraintEnd_toEndOf="parent"
            app:layout_constraintStart_toStartOf="parent"
            app:layout_constraintTop_toBottomOf="@+id/imageView2"
            tools:srcCompat="@tools:sample/avatars" />
    </androidx.constraintlayout.widget.ConstraintLayout>

</androidx.swiperefreshlayout.widget.SwipeRefreshLayout>

  4.2 测试方法

    //Volley 请求图片 2
    private void imageNetworkRequest(String url) {
        NetworkImageView imageView = findViewById(R.id.imageView2);
        RequestQueue queue = Volley.newRequestQueue(this);
        ImageLoader imageLoader = new ImageLoader(queue, new ImageLoader.ImageCache() {
            private LruCache<String, Bitmap> cache = new LruCache<>(50);

            @Nullable
            @Override
            public Bitmap getBitmap(String url) {
                return cache.get(url);
            }

            @Override
            public void putBitmap(String url, Bitmap bitmap) {
                cache.put(url, bitmap);
            }
        });
        imageView.setImageUrl(url, imageLoader);
    }

    //Volley 请求图片 1
    private void imageRequest(String url) {
        ImageView imageView = findViewById(R.id.imageView);
        RequestQueue queue = Volley.newRequestQueue(this);
        ImageLoader imageLoader = new ImageLoader(queue, new ImageLoader.ImageCache() {
            private LruCache<String, Bitmap> cache = new LruCache<>(50);

            @Nullable
            @Override
            public Bitmap getBitmap(String url) {
                return cache.get(url);
            }

            @Override
            public void putBitmap(String url, Bitmap bitmap) {
                cache.put(url, bitmap);
            }
        });
        imageLoader.get(url, new ImageLoader.ImageListener() {
            @Override
            public void onResponse(ImageLoader.ImageContainer response, boolean isImmediate) {
                imageView.setImageBitmap(response.getBitmap());
            }

            @Override
            public void onErrorResponse(VolleyError error) {
                Log.e(TAG, "onErrorResponse", error);
            }
        });
    }

5. Glide 的使用，测试方法

    //加载图片三
    private void imageGlideRequest(String url) {
        ImageView imageView = findViewById(R.id.imageView3);
        Glide.with(this)
                .load(url)
                .centerInside()
                .listener(new RequestListener<Drawable>() {
                    @Override
                    public boolean onLoadFailed(@Nullable GlideException e, Object model, Target<Drawable> target, boolean isFirstResource) {
                        if (refreshLayout.isRefreshing()) {
                            refreshLayout.setRefreshing(false);
                        }
                        return false;
                    }

                    @Override
                    public boolean onResourceReady(Drawable resource, Object model, Target<Drawable> target, DataSource dataSource, boolean isFirstResource) {
                        if (refreshLayout.isRefreshing()) {
                            refreshLayout.setRefreshing(false);
                        }
                        return false;
                    }
                })
                .into(imageView);
    }

6. Swiperefreshlayout 下拉刷新，测试方法

public class MainActivity extends AppCompatActivity {
    private String TAG = "My_Tag";
    private SwipeRefreshLayout refreshLayout;

    @Override
    protected void onCreate(Bundle savedInstanceState) {

        imageRequest(getUrl());
        imageNetworkRequest(getUrl());
        imageGlideRequest(getUrl());
        swipeRefreshLayout();
    }

    //随机取到一张图片
    private String getUrl() {
        String url[] = {"https://pixabay.com/get/g07fe87b77f48e5c8e5feeea776649bddd1736eae915f292a7d1ca15e63ba07fee19a3617baa91f0e20ffb14735c519b8_640.jpg",
