避免重复弹出toast

private static Toast toast;

    public static void showToast(Context context,
                                 String content) {
        if (toast == null) {
            toast = Toast.makeText(context,
                    content,
                    Toast.LENGTH_SHORT);
        } else {
            toast.setText(content);
        }
        toast.show();
    }

显示位置
toast = Toast.makeText(getApplicationContext(),
     "自定义位置Toast", Toast.LENGTH_LONG);
   toast.setGravity(Gravity.CENTER, 0, 0);
   toast.show();

带图片

toast = Toast.makeText(getApplicationContext(),
     "带图片的Toast", Toast.LENGTH_LONG);
   toast.setGravity(Gravity.CENTER, 0, 0);
   LinearLayout toastView = (LinearLayout) toast.getView();
   ImageView imageCodeProject = new ImageView(getApplicationContext());
   imageCodeProject.setImageResource(R.drawable.icon);
   toastView.addView(imageCodeProject, 0);
   toast.show();

完全自定义
LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.custom,
(ViewGroup) findViewById(R.id.llToast));
ImageView image = (ImageView) layout
.findViewById(R.id.tvImageToast);
image.setImageResource(R.drawable.icon);
TextView title = (TextView) layout.findViewById(R.id.tvTitleToast);
title.setText("Attention");
TextView text = (TextView) layout.findViewById(R.id.tvTextToast);
text.setText("完全自定义Toast");
toast = new Toast(getApplicationContext());
toast.setGravity(Gravity.RIGHT | Gravity.TOP, 12, 40);
toast.setDuration(Toast.LENGTH_LONG);
toast.setView(layout);
toast.show();
