Android's Toast simple implementation does not prompt cycle

Why 80% of the code can not do farming architect? >>>  

I do not know the program ape who have not encountered this problem in the project: Click on a view pop-up Toast, the method we are using Toast.makeText (context, "prompt", Toast.LENGTH_SHORT) .show (); however, careful people found, or if you frequently click on this view, will find that even though we pulled out of the application, or will have been prompted, which is obviously a little bit awkward and a little annoying. Here we give two ways to solve this problem.

1. Packaging a small Toast:

/**
 * 不循环提示的Toast
 * @author way
 *
 */
public class MyToast {
	Context mContext;
	Toast mToast;

	public MyToast(Context context) {
		mContext = context;

		mToast = Toast.makeText(context, "", Toast.LENGTH_SHORT);
		mToast.setGravity(17, 0, -30);//居中显示
	}

	public void show(int resId, int duration) {
		show(mContext.getText(resId), duration);
	}

	public void show(CharSequence s, int duration) {
		mToast.setDuration(duration);
		mToast.setText(s);
		mToast.show();
	}

	public void cancel() {
		mToast.cancel();
	}
}

2. The two functions function directly call: can be placed in an Activity, directly call showToast (String or int) when required; call hideToast in Activity of onPause () in () so that when the application exits, cancel annoying Toast.

/**
 * Show a toast on the screen with the given message. If a toast is already
 * being displayed, the message is replaced and timer is restarted.
 * 
 * @param message
 *            Text to display in the toast.
 */
private Toast toast;
private void showToast(CharSequence message) {
    if (null == toast) {
        toast = Toast.makeText(this, message,
                Toast.LENGTH_LONG);
        toast.setGravity(Gravity.CENTER, 0, 0);
    } else {
        toast.setText(message);
    }
 
    toast.show();
}
 
/** Hide the toast, if any. */
private void hideToast() {
    if (null != toast) {
        toast.cancel();
    }
}
