Android--Glide的使用

---

有一点要注意的就是，高版本不支持http明文。所以地址要写https

简单使用，点击按钮，执行各种方法。例子：

    //加载网络图片
    public void one(View view) {
        Glide.with(this).load("https://seopic.699pic.com/photo/50008/9194.jpg_wh1200.jpg").into(imageView);
    }

    //加载资源文件
    public void two(View view){
        Glide.with(this).load(R.drawable.jd).into(imageView);
    }

    //加载本地图片（SD卡）
    public void three(View view){
        String path= Environment.getExternalStorageDirectory()+"a.jpg";
        File file=new File(path);
        Uri uri=Uri.fromFile(file);
        Glide.with(this).load(uri).into(imageView);
    }

    //加载网络gif
    public void four(View view){
        String path="https://c-ssl.duitang.com/uploads/item/201410/23/20141023144603_8Mfxm.gif";
        //第三个是占位符，没加载过来之前先显示R.mipmap.ic_launcher
        Glide.with(this).load(path).placeholder(R.mipmap.ic_launcher).into(imageView);
    }

    //加载资源gif
    public void five(View view){
        Glide.with(this).load(R.drawable.a).into(imageView);
    }

    //加载本地gif
    public void six(View view){
        String path=Environment.getExternalStorageDirectory()+"a.gif";
        File file=new File(path);
        Glide.with(this).load(file).into(imageView);
    }

    //加载本地的小视频和快照
    public void seven(View view){
        String path=Environment.getExternalStorageDirectory()+"a.mp4";
        File videoFile=new File(path);
        Glide.with(this).load(Uri.fromFile(videoFile)).placeholder(R.mipmap.ic_launcher).into(imageView);
    }

    //设置缩略图比例，然后先加载缩略图，再加载原图
    public void eight(View view){
        String path="https://seopic.699pic.com/photo/50157/0224.jpg_wh1200.jpg";
        Glide.with(this).load(path).thumbnail(0.1f).centerCrop().placeholder(R.mipmap.ic_launcher).into(imageView);
    }

    //先建立一个缩略图对象，然后加载缩略图，再加载原图
    public void nine(View view){
        String path="https://seopic.699pic.com/photo/50157/0220.jpg_wh1200.jpg";
        String path2="https://seopic.699pic.com/photo/50157/0224.jpg_wh1200.jpg";
        RequestBuilder<Drawable> load = Glide.with(this).load(path2);
        Glide.with(this).load(path).thumbnail(load).centerCrop().placeholder(R.mipmap.ic_launcher).into(imageView);

    }

和recyclerview的使用：

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.MyViewHolder> {


    private Context context;

    public MyAdapter(Context context) {
        this.context = context;
    }

    @NonNull
    @Override
    public MyAdapter.MyViewHolder onCreateViewHolder(@NonNull ViewGroup parent, int viewType) {
        View view=View.inflate(context, R.layout.glide_item, null);
        return new MyViewHolder(view);
    }

    @Override
    public void onBindViewHolder(@NonNull MyAdapter.MyViewHolder holder, int position) {

        Glide.with(context).load(ImagePath.path[position]).into(holder.iv_item);
    }

    @Override
    public int getItemCount() {
        return ImagePath.path.length;
    }

    public class MyViewHolder extends RecyclerView.ViewHolder {

        private ImageView iv_item;

        public MyViewHolder(@NonNull View itemView) {
            super(itemView);
            iv_item=(ImageView)itemView.findViewById(R.id.iv_item);
        }
    }
}

public class ImagePath {

    public static String[] path={
            "https://seopic.699pic.com/photo/50008/9194.jpg_wh1200.jpg",
            "https://c-ssl.duitang.com/uploads/item/201410/23/20141023144603_8Mfxm.gif",
            "https://seopic.699pic.com/photo/50157/0224.jpg_wh1200.jpg"
    };
}

public class MyGlideRecycler extends AppCompatActivity {

    private RecyclerView recyclerView;
    private MyAdapter adapter;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my_glide_recycler);

    }
    public void initData(View view) {
        recyclerView=(RecyclerView)findViewById(R.id.rv_glide);
        adapter=new MyAdapter(this);
        recyclerView.setAdapter(adapter);
        recyclerView.setLayoutManager(new LinearLayoutManager(this, LinearLayoutManager.VERTICAL, false));
    }
}
