问题


After implementing the new Snackbar in a few of my applications, I am receiving the following error:

I am using the same setup here: 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();
        }
    }
}

Summary:

  • I am using the Snackbar
  • I am using the CoodinartorLayout
  • I am not using the DrawerLayout

Google Issues:

  • http://code.google.com/p/android/issues/detail?id=175501
  • http://code.google.com/p/android/issues/detail?id=103888

Based on the android.support.v4.widget.ViewDragHelper.shouldInterceptTouchEvent(SourceFile:1014) at line in the Exception, I am guessing it has to do with the "dismissing" of the Snackbar?

Maybe I should not dismiss the Snackbar in onPause? I used to do this with Toasts.


回答1:


One solution I found was to make sure it was not "swipe-able" by using findViewById(android.R.id.content). This solution basically "avoids" and prevents the error from happening.

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

Should be fixed in 23.2.1: https://stackoverflow.com/a/36004008/950427
