[视图]Toast优化,同一时间内部重复Toast N次

防止Toast N次,Toast一直不消失.

完整代码:

import android.widget.Toast;

public class Tools {

private static Toast mToast;

private static Handler mHandler = new Handler();private static Runnable r = new Runnable() {public void run() {mToast.cancel();}};

//调用showToast提示

public static void showToast(Context mContext, String text) {try {

	//每次调用先把前一个提示给remove掉mHandler.removeCallbacks(r);if (mToast != null) {mToast.setText(text);} else {mToast = Toast.makeText(mContext, text, Toast.LENGTH_SHORT);}mHandler.postDelayed(r, 2000);mToast.show();} catch (Resources.NotFoundException e) {e.printStackTrace();}}

public static void showToast(Context mContext, int resId) {showToast(mContext, mContext.getResources().getString(resId));}

}
