Android 自定义缩短Toast显示时间的实例代码

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
