3.Glide simple use case

(1) xml page layout

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout 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"
    android:orientation="vertical"
    tools:context=".MainActivity">

    <Button
        android:id="@+id/bt_pic_loader"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:text="加载图片" />

    <ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_marginTop="8dp" />

    <ImageView
        android:id="@+id/iv_pic"
        android:layout_width="match_parent"
        android:layout_height="wrap_content" />

</LinearLayout>

(2) java background

package com.example.administrator.test67glide;

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.ImageView;

import com.bumptech.glide.Glide;

public class MainActivity extends AppCompatActivity {

    Button bt_pic_loader;
    ImageView imageView;
    ImageView iv_pic;

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

        bt_pic_loader = the findViewById (R.id.bt_pic_loader); 
        the imageView = the findViewById (R.id.imageView); 
        iv_pic = the findViewById (R.id.iv_pic); 
        iv_pic.setImageResource (R.mipmap. news_pic_default); 
        iv_pic.setScaleType (ImageView.ScaleType.FIT_XY); // set of image scaling, Brand high filling parent control 

        bt_pic_loader.setOnClickListener ( new new View.OnClickListener () { 
            @Override 
            public  void the onClick (View V) {
                 // Glide load the network using the picture 
                String url = " http://118.25.152.62:8080/zhbj/10007/1452327318UU91.jpg " ;
                Glide.with(getApplicationContext()).load(url).into(imageView);

            }
