Question

我正在学习 Android Glide 我正在创建一个简单的应用程序，它使用 Glide 将图像从网络显示到 imageview 但每次当我运行这个应用程序

MainActivity.java代码

package com.example.cs.myglideapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ImageView;
import com.bumptech.glide.Glide;

public class MainActivity extends AppCompatActivity {

    private ImageView img1;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        img1 = findViewById(R.id.img1);

        // urls to show on imageview
        //String[] urls = {
            //"https://cdn.pixabay.com/photo/2016/03/04/01/46/bottles-1235327_960_720.jpg",
            //"https://cdn.pixabay.com/photo/2017/06/24/23/41/beer-2439237_960_720.jpg"};

        //loading image into ImageView 
        Glide.with(this)
            .load("https://cdn.pixabay.com/photo/2016/03/04/01/46/bottles-1235327_960_720.jpg")
            .into(img1);
    }

Answer 1

您忘记添加 setContentView(R.layout.activity_main);

package com.example.cs.myglideapp;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.ImageView;
import com.bumptech.glide.Glide;

public class MainActivity extends AppCompatActivity {

    private ImageView img1;


    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main); // Add this line

        img1 = findViewById(R.id.img1);

        //loading image into ImageView 
       Glide.with(this).load("https://cdn.pixabay.com/photo/2016/03/04/01/46/bottles-1235327_960_720.jpg").into(img1);

    }
}
