我这个主要是缩短Toast显示时间,要延长时间的话,可自行更改
废话不多说哈,见代码
import android.content.Context; import android.os.CountDownTimer; import android.util.Log; import android.widget.Toast; public class ToastUtil { private String TAG = "ToastUtil"; private Toast mToast; private TimeCount timeCount; private String message; private boolean canceled = true; public ToastUtil(Context context,String msg) { message = msg; Log.i("ToastUtil","Toast start..."); if (mToast == null) { mToast =Toast.makeText(context,message,Toast.LENGTH_SHORT); Log.i("ToastUtil","Toast create..."); } } /** * 自定义居中显示toast */ public void show() { mToast.show(); Log.i("ToastUtil","Toast show..."); } /** * 自定义时长、居中显示toast * @param duration */ public void show(int duration) { timeCount = new TimeCount(duration,100); Log.i("ToastUtil","Toast show..."); if (canceled) { timeCount.start(); show(); canceled = false; } } /** * 隐藏toast */ private void hide() { if (mToast != null) { mToast.cancel(); } canceled = true; Log.i("ToastUtil","Toast that customed duration hide..."); } /** * 自定义计时器 */ private class TimeCount extends CountDownTimer { public TimeCount(long millisInFuture,long countDownInterval) { super(millisInFuture,countDownInterval); //millisInFuture总计时长,countDownInterval时间间隔(一般为1000ms) } @Override public void onTick(long millisUntilFinished) { Log.e(TAG,": " + millisUntilFinished / 100 + "后消失" ); } @Override public void onFinish() { hide();//记数结束后调用取消Toast的显示 } } }
使用方式:
ToastUtil toastUtil = new ToastUtil(MainActivity.this,"保存成功!");//MainActivity.this为 //Context,toastUtil.show(500);
总结
以上所述是小编给大家介绍的Android 自定义缩短Toast显示时间的实例代码,希望对大家有所帮助!
