ArrayIndexOutOfBoundsException khi gạt bỏ Snackbar/ViewDragHelper

Question

Sau khi thực hiện mới Snackbar trong một vài ứng dụng của tôi, tôi nhận được lỗi sau:

Tôi đang sử dụng các thiết lập tương tự ở đây: https://github.com/chrisbanes/cheesesquare/blob/master/app/src/main/java/com/support/android/designlibdemo/MainActivity.java

public class MainActivity extends AppCompatActivity { 

    private Snackbar snackbar;  

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

     Toolbar toolbar = (Toolbar) findViewById(R.id.toolbar); 
     setSupportActionBar(toolbar); 

     FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab); 
     fab.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 

       // if showing already, close 
       if (this.snackbar != null) { 
        this.snackbar.dismiss(); 
       } 

       // make new snackbar 
       this.snackbar = Snackbar.make(view, "Here's a Snackbar", Snackbar.LENGTH_LONG).show(); 


       // chris banes example 
       // Snackbar.make(view, "Here's a Snackbar", Snackbar.LENGTH_LONG).setAction("Action", null).show(); 

      } 
     }); 
    } 

    @Override 
    public void onPause() { 
     super.onPause(); 
     // dismiss when user clicks "home" 
     if (this.snackbar != null) { 
      this.snackbar.dismiss(); 
     } 
    } 
} 

Tóm tắt:

• Tôi đang sử dụng Snackbar
• Tôi đang sử dụng CoodinartorLayout
• Tôi không sử dụng các vấn đề với Google DrawerLayout

Dựa trên dòng android.support.v4.widget.ViewDragHelper.shouldInterceptTouchEvent(SourceFile:1014) at trong Ngoại lệ, tôi đoán nó có liên quan đến việc "loại bỏ" số Snackbar?

Có lẽ tôi không nên dismiss số Snackbar trong ? Tôi đã từng làm điều này với Toast s.

Answer 1

Một giải pháp mà tôi tìm thấy là đảm bảo rằng giải pháp không phải là "có thể vuốt" bằng cách sử dụng findViewById(android.R.id.content). Giải pháp này về cơ bản "tránh" và ngăn chặn các lỗi xảy ra.

Snackbar.make(findViewById(android.R.id.content), "Hello!", Snackbar.LENGTH_LONG);
