如何集中定制的创作干杯 [英] How to centralize a custom toast creation

问题描述

在我的应用程序中使用自定义土司几乎所有的活动。要创建自定义的敬酒，我有以下方法：

in my application i use a custom toast in almost all the activity. To create the custom toast i have the following method :

private void getCustomToast(String message)
{
    LayoutInflater li   = getLayoutInflater();
    View toastlayout    = li.inflate(R.layout.toast_error, (ViewGroup)findViewById(R.id.toast_layout));
    TextView text       = (TextView) toastlayout.findViewById(R.id.toast_text);
    text.setText(message);

    Toast toast = new Toast(this);
    toast.setDuration(Toast.LENGTH_LONG);
    toast.setView(toastlayout);
    toast.show();
}

它工作正常，但每一项活动，我需要重复这种方法，而不是真的respectfull的DRY原则......

It works fine but for each activity I need to duplicate this method, not really respectfull of the DRY principle ...

我怎样才能让一个静态类（例如），其中我有要去火的方法对当前活动自定义敬酒？

How can i make a static class (for example) in which i have a method which gonna fire the custom toast on the current activity ?

感谢

推荐答案

您应该包含烤面包的方法自定义抽象的活动，然后扩大，对应用程序的活动：

You should make a custom abstract Activity that contains the toast method, and then extend that for your application's activities:

public abstract class ToastActivity extends Activity {

    protected void getCustomToast(String message)
    {
        LayoutInflater li = getLayoutInflater();
        View toastlayout  = li.inflate(
                R.layout.toast_error, 
                (ViewGroup) findViewById(R.id.toast_layout));

        TextView text = (TextView) toastlayout.findViewById(R.id.toast_text);
        text.setText(message);

        Toast toast = new Toast(this);
        toast.setDuration(Toast.LENGTH_LONG);
        toast.setView(toastlayout);
        toast.show();
    }

}
