Image not showing no matter what(Picasso,Glide,Async)

问题

不管我做什么，图片就是不显示。

我已经写了最简单的代码来进行测试，但我确实需要一些帮助。

我没有收到任何错误和崩溃，所以我不知道该怎么办。

我尝试过使用 Glide 和 Asynce，但都没有成功。

顺便说一下，在 Android 清单文件中添加了用户权限：

  1. <uses-permission android:name="android.permission.INTERNET"></uses-permission>
  2. <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>

谢谢！

  1. public class MainActivity extends AppCompatActivity {
  3.     @Override
  4.     protected void onCreate(Bundle savedInstanceState) {
  5.         super.onCreate(savedInstanceState);
  6.         setContentView(R.layout.activity_main);
  8.         ImageView myImage = (ImageView) findViewById(R.id.mImageView);
  9.         Picasso.get().load("https://i.imgur.com/tGbaZCY.jpg").into(myImage);
  10.     }
  11. }

ImageView 代码：

  1. <ImageView
  2.     android:id="@+id/mImageView"
  3.     android:layout_width="0dp"
  4.     android:layout_height="0dp"
  5.     android:layout_marginStart="32dp"
  6.     android:layout_marginLeft="32dp"
  7.     android:layout_marginTop="32dp"
  8.     android:layout_marginEnd="32dp"
  9.     android:layout_marginRight="32dp"
  10.     android:layout_marginBottom="32dp"
  11.     app:layout_constraintBottom_toBottomOf="parent"
  12.     app:layout_constraintEnd_toEndOf="parent"
  13.     app:layout_constraintStart_toStartOf="parent"
  14.     app:layout_constraintTop_toTopOf="parent" />

问题出在模拟器上！！！

简直不敢相信，感觉自己太菜了哈哈。

英文:

No matter what I do,the picture just doesn't want to show.

I have done the simplest code just for the test and I can really use some help.

I am getting no errors and no crashes,so I have no clue what to do.

I tried to use Glide and Asynce also but with no success.

btw,I added user permission on android manifest:

  1. &lt;uses-permission android:name=&quot;android.permission.INTERNET&quot;&gt;&lt;/uses-permission&gt;
  2. &lt;uses-permission android:name=&quot;android.permission.ACCESS_NETWORK_STATE&quot;&gt;&lt;/uses-permission&gt;

Thank you!

好的，我花了几个小时来找出问题所在。

模拟器是问题的源头！！！

我在手机上试了一下，可以运行！

下次我肯定会把手机设为默认。

感谢所有的回复者！！

试试这个

Xml

  1. <?xml version="1.0" encoding="utf-8"?>
  2. <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
  3.     xmlns:app="http://schemas.android.com/apk/res-auto"
  4.     xmlns:tools="http://schemas.android.com/tools"
  5.     android:layout_width="match_parent"
  6.     android:layout_height="match_parent"
  7.     tools:context=".MainActivity">
  10.     <ImageView
  11.         android:id="@+id/imageView"
  12.         android:layout_width="wrap_content"
  13.         android:layout_height="wrap_content"
  14.         app:layout_constraintBottom_toBottomOf="parent"
  15.         app:layout_constraintEnd_toEndOf="parent"
  16.         app:layout_constraintStart_toStartOf="parent"
  17.         app:layout_constraintTop_toTopOf="parent"
  18.         tools:srcCompat="@tools:sample/avatars" />
  19. </androidx.constraintlayout.widget.ConstraintLayout>

MainActivity

  1. public class MainActivity extends AppCompatActivity {
  3.     @Override
  4.     protected void onCreate(Bundle savedInstanceState) {
  5.         super.onCreate(savedInstanceState);
  6.         setContentView(R.layout.activity_main);
  8.         ImageView myImage = (ImageView) findViewById(R.id.imageView);
  9.         Glide.with(MainActivity.this)
  10.                 .load("https://i.imgur.com/tGbaZCY.jpg")
  11.                 .into(myImage);
  13.     }
  14. }

添加这部分

  1. implementation 'com.github.bumptech.glide:glide:4.11.0'

在你的清单文件中

  1. <uses-permission android:name="android.permission.INTERNET"/>
  2. <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
英文:

Try this

Xml

  1. &lt;?xml version=&quot;1.0&quot; encoding=&quot;utf-8&quot;?&gt;
  2. &lt;androidx.constraintlayout.widget.ConstraintLayout xmlns:android=&quot;http://schemas.android.com/apk/res/android&quot;
  3.     xmlns:app=&quot;http://schemas.android.com/apk/res-auto&quot;
  4.     xmlns:tools=&quot;http://schemas.android.com/tools&quot;
  5.     android:layout_width=&quot;match_parent&quot;
  6.     android:layout_height=&quot;match_parent&quot;
  7.     tools:context=&quot;.MainActivity&quot;&gt;
  10.     &lt;ImageView
  11.         android:id=&quot;@+id/imageView&quot;
  12.         android:layout_width=&quot;wrap_content&quot;
  13.         android:layout_height=&quot;wrap_content&quot;
  14.         app:layout_constraintBottom_toBottomOf=&quot;parent&quot;
  15.         app:layout_constraintEnd_toEndOf=&quot;parent&quot;
  16.         app:layout_constraintStart_toStartOf=&quot;parent&quot;
  17.         app:layout_constraintTop_toTopOf=&quot;parent&quot;
  18.         tools:srcCompat=&quot;@tools:sample/avatars&quot; /&gt;
  19. &lt;/androidx.constraintlayout.widget.ConstraintLayout&gt;

MainActivity

  1. public class MainActivity extends AppCompatActivity {
  3.     @Override
  4.     protected void onCreate(Bundle savedInstanceState) {
  5.         super.onCreate(savedInstanceState);
  6.         setContentView(R.layout.activity_main);
  8.         ImageView myImage = (ImageView) findViewById(R.id.imageView);
  9.         Glide.with(MainActivity.this)
  10.                 .load(&quot;https://i.imgur.com/tGbaZCY.jpg&quot;)
  11.                 .into(myImage);
  13.     }
  14. }

ADD this

  1. implementation &#39;com.github.bumptech.glide:glide:4.11.0&#39;

In Your Manifest

  1. &lt;uses-permission android:name=&quot;android.permission.INTERNET&quot;/&gt;
  2. &lt;uses-permission android:name=&quot;android.permission.ACCESS_NETWORK_STATE&quot;/&gt;
