Glide如何显示一张张不同的图片？

Question

我想延迟显示另一张图片。这是我的代码：

public class MainActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    ImageView imageView=findViewById(R.id.imageView);

    ArrayList<String> test = new ArrayList<String>();
    test.add("e");
    test.add("a");
    if (test.get(0) == "e") {
        Glide.with(this)
                .load("https://something.something/something.jpg")
                .into(imageView);
        try {
            Thread.sleep(3000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }
    if (test.get(1) == "a") {
        Glide.with(this)
                .load("https://something.something/something2.jpg")
                .into(imageView);
    }
}
}

但如果我这样做，只会出现第二张图片。有什么解决办法吗？

Answer 1

创建新方法

private void loadImage(String imageLink){
    Glide.with(this).load(imageLink).into(imageView);
}

现在只需在您想要在同一个 imageView 中加载第一张图片和第二张图片的地方调用它

loadImage("imageLink");

final Handler handler = new Handler();
handler.postDelayed(new Runnable() {
    @Override
    public void run() {
        //Do something after 3sec
        loadImage("next ImageLink");
    }
}, 3000);

像这样，你也可以修改loadImage方法，如果你想延迟加载不同ImageView中的图像，它也可以接受ImageView作为参数

if (test.get(0) == "e") {
    loadImage("https://something.something/something.jpg");
}
if (test.get(1) == "a") {
    final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            //Do something after 3sec (3000 = 3 sec)
            loadImage("https://something.something/something2.jpg");
        }
    }, 3000);
}

希望这对您有所帮助！

如果您想延迟加载两张图片，请使用

if (test.get(0) == "e") {
    final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            //Do something after 3sec (3000 = 3 sec)
            loadImage("https://something.something/something.jpg"); // image 1 
        }
    }, 3000);
}
if (test.get(1) == "a") {
    final Handler handler = new Handler();
    handler.postDelayed(new Runnable() {
        @Override
        public void run() {
            //Do something after 3sec (3000 = 3 sec)
            loadImage("https://something.something/something2.jpg"); // image 2
        }
    }, 3000);
}
