显示吐司时出错

Question

我正在尝试按顺序运行toast以显示ruuning rss feed.运行时出现以下错误:java.lang.RuntimeException:此Toast未使用Toast.makeText()创建

我的代码是:

LayoutInflater inflater = getLayoutInflater();
View layout = inflater.inflate(R.layout.toast_layout,
                               (ViewGroup) findViewById(R.id.toast_layout_root));

ImageView image = (ImageView) layout.findViewById(R.id.toastimage);
image.setImageResource(R.drawable.bball_icon);
TextView text = (TextView) layout.findViewById(R.id.toasttext);

Toast toast = new Toast(getApplicationContext());
toast.setView(layout);
for (int i=0;i<episode_titles.size();i++)
{
    toast.setText(episode_titles.get(i).toString());
    toast.setGravity(Gravity.CENTER_VERTICAL, 0, 0);
    toast.setDuration(Toast.LENGTH_SHORT);

    toast.show();

}

Answer 1

要将文本设置为toast,您必须通过它进行初始化makeText.

像这样:

    Toast toast = Toast.makeText(this, "message", Toast.LENGTH_SHORT);
    toast.setText("new message");
    toast.setGravity(Gravity.CENTER, 0, 0);
    //other setters
    toast.show();

Answer 2

Toast U 可以这样指定...

  Toast.makeText(getApplicationContext(), "hai", Toast.LENGTH_LONG).show();

那么你可以这样写...

       String s=episode_titles.get(i).toString();
      Toast.makeText(getApplicationContext(), "UrMessage:"+s, Toast.LENGTH_LONG).show();
