android.support.design.widget.CoordinatorLayout

原始XML代码文件有一个相对布局加上其他项和用于CoordinatorLayout小部件的XML

    public void showSnackbar(){

    //coordinatorLayout = findViewById(snackbarView);

    //Snackbar snackbar = null;
        final Snackbar snackbar = Snackbar
                .make(findViewById(snackbarView), getText(R.string.snackbar_text),1);
                snackbar.setActionTextColor(Color.RED);
                snackbar.setAction("EXIT", new View.OnClickListener(){

            @Override
            public void onClick(View view) {
                //Intent intent = new Intent(DetailsActivity.this, MainActivity.class);
                //startActivity(intent);
                snackbar.dismiss();
            }
        });

        TextView snackbarActionTextView  = (TextView) snackbar.getView().findViewById( android.support.design.R.id.snackbar_action );
        snackbarActionTextView.setTextSize( 30 );
        snackbarActionTextView.setTypeface(snackbarActionTextView.getTypeface(), Typeface.BOLD);

        TextView snackbarTextView = (TextView) snackbar.getView().findViewById(android.support.design.R.id.snackbar_text);
        snackbarTextView.setTextSize( 30 );
        snackbarTextView.setMaxLines( 3 );
        snackbarTextView.setTextColor(Color.YELLOW);
        snackbar.setDuration(Snackbar.LENGTH_INDEFINITE);
        snackbar.show();

    }

这是我的进口

  import android.support.design.widget.Snackbar;
  import android.support.v7.app.AppCompatActivity;
