package com.geely.util;

import android.content.Context;
import android.support.annotation.StringRes;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;

import com.geely.main.R;

public class MyToastUtil {
private Toast mToast;
TextView textView;
int mDuration;
public @interface Duration {}
private MyToastUtil(Context context, @StringRes int resId, int duration) {
View v = LayoutInflater.from(context).inflate(R.layout.layout_toast, null);
textView = (TextView) v.findViewById(R.id.toast_text);
textView.setText(resId);
mToast = new Toast(context);
mToast.setDuration(duration);
mToast.setView(v);
}

public static MyToastUtil makeText(Context context, @StringRes int resId, int duration) {
    return new MyToastUtil(context, resId, duration);
}
public void show() {
    if (mToast != null) {
        mToast.show();
    }
}
public void setGravity(int gravity, int xOffset, int yOffset) {
    if (mToast != null) {
        mToast.setGravity(gravity, xOffset, yOffset);
    }
}
public void setText(@StringRes int resId) {
    textView.setText(resId);
}
public void setDuration(@Duration int duration) {
    mDuration = duration;
}

}

private MyToastUtil mytoast = null;
if (mytoast != null) {
