本文为大家分享了Toast类避免显示时间叠加的方法，供大家参考，具体内容如下
import android.app.Activity;
import android.app.Fragment;
import android.content.Context;
import android.widget.Toast;
/**

public class ToastUtil {
private static Toast toast = null;
private static ToastUtil toastUtil = null;
public ToastUtil(){}
public synchronized static ToastUtil getInstance(){
if(null == toastUtil){
toastUtil = new ToastUtil();
}
return toastUtil;
}
public void showToast(Context context, String string){
if(toast != null){
toast.cancel();
}
toast = Toast.makeText(context, string,Toast.LENGTH_SHORT);
toast.show();
}
public void showToast(Fragment fragment, String string){
showToast(fragment.getActivity(),string);
}
public void showToast(Activity activity, String string){
if(toast != null){
toast.cancel();
}
toast = Toast.makeText(activity, string,Toast.LENGTH_SHORT);
toast.show();
}
public void showToastTest(Context context){
if(toast != null){
toast.cancel();
}
toast = Toast.makeText(context, "click",Toast.LENGTH_SHORT);
toast.show();
}
public void showToastTest(Fragment fragment){
showToastTest(fragment.getActivity());
}
public void showToastTest(Activity activity){
if(toast != null){
toast.cancel();
}
toast = Toast.makeText(activity, "click",Toast.LENGTH_SHORT);
toast.show();
}
}
if(null == toastUtil){
toastUtil = new ToastUtil();
}
return toastUtil;
}
public void showToastInThread(Context context,String msg){
Looper.prepare();
if(toast != null){
toast.cancel();
}
toast = Toast.makeText(context,msg,Toast.LENGTH_SHORT);
toast.show();
Looper.loop();
}
public void showToast(Context context, String string){
if(toast != null){
toast.cancel();
}
toast = Toast.makeText(context, string,Toast.LENGTH_SHORT);
toast.show();
}
}
这是一个封装好的Toast工具类，避免时间叠加
使用方法
ToastUtil.getInstance().showToast(mContext,"test");
如果在线程中执行的话，必须按照如下格式
ToastUtil.getInstance().showToastInThread(mContext,"str");
