滑翔 - 应用程序崩溃与上下文错误在另一个活动

我有一个问题Glide。这个问题发生在这样：滑翔 - 应用程序崩溃与上下文错误在另一个活动

我去我的个人资料页，然后我点击返回按钮，然后我在火力地堡数据库（现在的应用程序崩溃）插入的对象。这个问题在我的UserProfile活动，但我不知道如何解决这个问题。我读过两篇类似的文章，但我不太明白。（Glide error after activity was destroyed and restarted和Glide image loading with application context）

我logcat是这样的：

档案类：

public class UserProfile extends AppCompatActivity { 

Context mContext; 
ImageView userProfileImage; 
TextView name, mail, user_location_textView; 
String tag_login; 
String user_name, user_mail, user_token, user_urlPicture, user_location, user_key; 
String TAG_LOGIN = "TAG_LOGIN"; 
String KEY = "KEY"; 
int REQUEST_IMAGE_CAPTURE; 
DatabaseReference users; 

@TargetApi(Build.VERSION_CODES.KITKAT) 
@Override 
protected void onCreate(Bundle savedInstanceState) { 
    super.onCreate(savedInstanceState); 
    setContentView(layout.activity_user_profile); 
    getSupportActionBar().hide(); 

    mContext = this; 

    userProfileImage = (ImageView) findViewById(R.id.imageProfile); 
    name = (TextView) findViewById(R.id.name); 
    mail = (TextView) findViewById(R.id.mail); 
    user_location_textView = (TextView) findViewById(R.id.user_location); 

    Intent intent = getIntent(); 
    tag_login = intent.getStringExtra(TAG_LOGIN); 
    user_key = intent.getStringExtra(KEY); 

    users = FirebaseDatabase.getInstance().getReference("Users").child("User" + tag_login).child(user_key); 

    users.addValueEventListener(new ValueEventListener() { 
     @RequiresApi(api = Build.VERSION_CODES.KITKAT) 
     @Override 
     public void onDataChange(DataSnapshot dataSnapshot) { 
      getUserData(dataSnapshot); 
     } 
     @Override 
     public void onCancelled(DatabaseError databaseError) { 
     } 
    }); 

} 


///Get user's data with the key/// 

@TargetApi(Build.VERSION_CODES.KITKAT) 
@RequiresApi(api = Build.VERSION_CODES.KITKAT) 
private void getUserData(DataSnapshot dataSnapshot){ 
    if (Objects.equals(tag_login, "App")){ 
     UserApp userApp = dataSnapshot.getValue(UserApp.class); 
     user_name = userApp.user_name; 
     user_mail = userApp.user_mail; 
     user_token = userApp.user_token; 
     user_location = userApp.user_location; 
     user_urlPicture = userApp.user_bitmapImage; 
     name.setText(user_name); 
     mail.setText(user_mail); 
     user_location_textView.setText(user_location); 
     if (Objects.equals(user_urlPicture, "NoImage")){ 
      userProfileImage.setImageResource(drawable.noimage); 
      Toast.makeText(mContext, "Click on image to change it", Toast.LENGTH_LONG).show(); 
     } else { 
      Glide.with(mContext).load(user_urlPicture).into(userProfileImage); 
     } 
     userProfileImage.setOnTouchListener(new View.OnTouchListener() { 
      @Override 
      public boolean onTouch(View v, MotionEvent event) { 
       Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); 
       if (takePictureIntent.resolveActivity(getPackageManager()) != null) { 
        REQUEST_IMAGE_CAPTURE = 1; 
        startActivityForResult(takePictureIntent, REQUEST_IMAGE_CAPTURE); 
       } 
       return false; 
      } 
     }); 


    } 

}

请张贴出来的代码。 –

后您USERPROFILE –

类我已经更新了我的问题 – Carlo

您应该在活动期间删除值变化监听器的onDestroy。

事情是这样的：

// during onCreate(Bundle) 
users.addValueEventListener(listener); 

// then during onDestroy() 
users.removeValueEventListener(listener); 

// outside any method you write the listener 
private ValueEventListener listener = new ValueEventListener() { 
     @RequiresApi(api = Build.VERSION_CODES.KITKAT) 
     @Override 
     public void onDataChange(DataSnapshot dataSnapshot) { 
      getUserData(dataSnapshot); 
     } 
     @Override 
     public void onCancelled(DatabaseError databaseError) { 
     } 
    }

非常感谢@Budius – Carlo

最有可能当用户已经从导航的活动了你的听众接到电话。当活动被破坏时，您需要删除侦听器。或者至少在设置文本之前检查这些视图是否为空。
