Android学习之关于Toast

自定义Toast时间（ms级别）

/*自定义Toast时间实现(ms级别)*/
public static void showToast(final Activity activity, final String word, final long time){
    activity.runOnUiThread(new Runnable() { 
        public void run() {
            final Toast toast = Toast.makeText(activity, word, Toast.LENGTH_LONG);
            toast.show();
            Handler handler = new Handler();
                handler.postDelayed(new Runnable() {
                   public void run() {
                       toast.cancel(); 
                   }
            }, time);
        }
    });
}

显示期间重复触发叠加显示的解决

public class Util {

    private static Toast toast;

    public static void showToast(Context context, 
        String content) {
        if (toast == null) {
            toast = Toast.makeText(context,
                         content, 
                         Toast.LENGTH_SHORT);
        } else {
            toast.setText(content);
        }
        toast.show();
    }
}
