Question

我正在尝试使用Listview根据前一个视图的字符串更改TextView中的文本。

由于某种原因，它会一直返回错误。这是我的代码：

public class LyricsFragment extends Fragment {
    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {


        /** Inflating the layout country_details_fragment_layout to the view object v */
        View v = inflater.inflate(R.layout.learnlyrics, null);

        /** Getting the textview object of the layout to set the details */
        TextView tv = (TextView) v.findViewById(R.id.learnsong);

        Bundle b = getArguments();

        tv.setText("Details of " + Country.name[b.getInt("position")]);

        int position = b.getInt("position");


        String s = b.getInt("position");
        if (s.startsWith("Pretty Hurts")) {

            tv.setText("[Intro]\\nHarvey Keitel: Ms. Third Ward, your first question -- what is your aspiration in life?\\n" +
                    "Beyoncé: Oh, my aspiration in life would be to be happy\\n\\n[Verse 1]\\nMama said, you're a pretty girl\\n " +
                    "What's in your head it doesn't matter\\nBrush your hair, fix your teeth\\nWhat you wear is all that matters\\n\\n[Pre-Hook]\\nJust another stage\\nPageant the pain away\\nThis time I'm gonna take the crown\\nWithout falling down, down\\n\\n[Hook]\\nPretty hurts\\nWe shine the light on whatever's worse\\nPerfection is the disease of a nation\\nPretty hurts, pretty hurts\\nWe shine the light on whatever's worse\\nTryna fix something\\nBut you can't fix what you can't see\\nIt's my soul that needs the surgery\\n\\n[Verse 2]\\nBlonder hair, flat chest\\nTV says bigger is better\\nSouth beach, sugar free\\nVogue says thinner is better\\n\\n[Pre-Hook + Hook]\\n\\n[Bridge]\\nAin’t got no doctor or pill that can take the pain away\\nThe pain's inside\\nAnd nobody frees you from your body\\nIt's the soul, its the that needs surgery\\nIt's the soul that needs surgery\\nPlastic smiles and denial can only take you so far\\nThen you break when the fake facade leaves you in the dark\\nYou left a shattered mirror\\nAnd the shards of a beautiful girl\\n\\n[Hook]\\n\\n[Outro]\\nWhen you're alone all by yourself\\nAnd you're lying in your bed\\nReflection stares right into you\\nAre you happy with yourself?\\nIt's just a way to masquerade\\nThe illusion has been shed\\nAre you happy with yourself?\\nAre you happy with yourself?\\nYes\\n");

        }

        return v;
    }
}

错误是：

String s = b.getInt("position");

作为一名新的Android开发者，我不确定为什么？请帮忙。

Answer 1

错误由@JonasCz

表示

你需要从int转换为String，因为你不能将int存储到String变量中！

String s = String.valueOf(b.getInt("position"));

Answer 2

想出来了。将意图更改为活动，活动具有以下代码：

public class SongLyrics extends Activity {

Context context;
String[] rank;
int position;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    /** Setting the layout for this activity */
    setContentView(R.layout.learnlyrics);


    String title = getIntent().getExtras().getString("rank");

    Intent i = getIntent();
    position = i.getExtras().getInt("position");
    rank = i.getStringArrayExtra("rank");


    TextView titleTextView = (TextView) findViewById(R.id.learnsong);

  //  titleTextView.setText(title);

    titleTextView.setText(rank[position]);



}
}

根据String更改Textview
