Android 自定义 Toast 显示时间

Android 自定义 Toast 显示时间

实现代码：

package com.wm.realname.util;
import android.content.Context;
import android.os.Handler;
import android.view.View;
import android.widget.Toast;

public class ToastUtil {
 private Context mContext = null;
 private Toast mToast = null;
 private Handler mHandler = null;
 private int duration = 0;
 private int currDuration = 0;
 private final int DEFAULT = 2000;
 private Runnable mToastThread = new Runnable() {
  public void run() {
   mToast.show();
   mHandler.postDelayed(mToastThread, DEFAULT); // 每隔2秒显示一次
   if (duration != 0) {
    if (currDuration <= duration) {
     currDuration += DEFAULT;
    } else {
     cancel();
    }
   }
  }
 }
 public ToastUtil(Context context) {
  mContext = context;
  currDuration = DEFAULT;
  mHandler = new Handler(mContext.getMainLooper());
  mToast = Toast.makeText(mContext, "", Toast.LENGTH_LONG);
 }
 public void setText(String text) {
  mToast.setText(text);
 }
 public void show(int duration) {
  this.duration = duration;
  mHandler.post(mToastThread);
 }
 public void setGravity(int gravity, int xOffset, int yOffset) {
  mToast.setGravity(gravity, xOffset, yOffset);
 }
 public void setDuration(int duration) {
  mToast.setDuration(duration);
 }
 public void setView(View view) {
  mToast.setView(view);
 }
 public void cancel( ) {
  mHandler.removeCallbacks(mToastThread);// 先把显示线程删除
  mToast.cancel();// 把最后一个线程的显示效果cancel掉，就一了百了了
  currDuration = DEFAULT;
 }
}
