如何使用Glide依次显示不同的图像？

Question

我想在延迟后显示其他图像。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);
    }
}
}

但是如果我这样做的话，只有第二张图片适用。有解决方案吗？

Answer 1

创建新方法

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

现在只需在要在同一imageView中加载第一张图像和第二张图像的位置调用此名称

loadImage("imageLink");

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

类似的事情，您还可以修改loadImage方法，以便如果要延迟将图像加载到其他ImageView中，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);
}

希望这会有所帮助！

编辑1：

如果要同时加载两个图片，请延迟使用

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);
}
