二。自定义Toast
二。一 自定义Toast类代码：
package com.chencheng.utils;
import android.content.Context;
import android.view.Gravity;
import android.view.LayoutInflater;
import android.view.View;
import android.widget.TextView;
import android.widget.Toast;
import com.yuchen.meituan.R;
public class ToastUtil {
private static Toast toast;
public static void showToast(Context context, String text) {
// Toast toast = Toast.makeText(this, "toast", Toast.LENGTH_LONG);
// 如果之前有任务，就取消
if (toast != null) {
toast.cancel();
}
toast = new Toast(context);
View view = LayoutInflater.from(context).inflate(R.layout.toast_custom,
null);
TextView tvText = (TextView) view.findViewById(R.id.tv_content);
tvText.setText(text);
// toast.setBackground();
toast.setView(view);
toast.setGravity(Gravity.BOTTOM, 0, 100);
toast.setDuration(Toast.LENGTH_SHORT);
toast.show();
}
private ToastUtil() {
}
}
