java - 我无法将 View 添加到我的 viewflipper

Question

这是我的代码:

public View anEpisode(String n, String i, String d){
    View v;
    LayoutInflater inflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    v = inflater.inflate(R.layout.episodedescription, null);

    TextView nameOfEpisode = (TextView) findViewById(R.id.episodedescriptionname);
    ImageView imageOfEpisode = (ImageView) findViewById(R.id.episodedescriptionimage);
    TextView descriptionOfEpisode = (TextView) findViewById(R.id.episodedescriptiondescription);

    nameOfEpisode.setText(n);
    descriptionOfEpisode.setText(d);
    createUrlImage(imageOfEpisode, i);

    return v;
}


    flipper.addView(anEpisode("test", "url image", "test description"));

我的错误在这一行:

    nameOfEpisode.setText(n);

你们能帮我吗？也许是因为我的充气机？

我认为您需要对 inflater.inflate 的结果调用 findViewById (注意 v.):

public View anEpisode(String n, String i, String d){
    View v;
    LayoutInflater inflater = (LayoutInflater)getBaseContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    v = inflater.inflate(R.layout.episodedescription, null);

    TextView nameOfEpisode = (TextView) v.findViewById(R.id.episodedescriptionname);
    ImageView imageOfEpisode = (ImageView) v.findViewById(R.id.episodedescriptionimage);
    TextView descriptionOfEpisode = (TextView) v.findViewById(R.id.episodedescriptiondescription);

    nameOfEpisode.setText(n);
    descriptionOfEpisode.setText(d);
    createUrlImage(imageOfEpisode, i);

    return v;
}


flipper.addView(anEpisode("test", "url image", "test description"));
