シンプルな電話帳 Android アプリを作成しようとしていますが、それを実行しようとすると、大量のエラーが発生し、間違いを探す場所がまったくわかりません。私が今やろうとしているのは、ファイルから名前のリストを読み取り、それを ListView に表示することだけです。これはコードです:
public class MainActivity extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
final ListView listview = (ListView) findViewById(R.id.listView1);
final ArrayList<String> names = new ArrayList<String>();
try
{
Scanner sc = new Scanner(getAssets().open(String.format("data.txt")));
while(sc.hasNextLine())
{
names.add(sc.nextLine());
}
} catch (IOException ioe) { System.out.println("Failed to load file"); }
final StableArrayAdapter adapter = new StableArrayAdapter(this,
R.id.listView1, names);
listview.setAdapter(adapter);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
private class StableArrayAdapter extends ArrayAdapter<String> {
HashMap<String, Integer> mIdMap = new HashMap<String, Integer>();
public StableArrayAdapter(Context context, int textViewResourceId,
List<String> objects) {
super(context, textViewResourceId, objects);
for (int i = 0; i < objects.size(); ++i) {
mIdMap.put(objects.get(i), i);
}
}
@Override
public long getItemId(int position) {
String item = getItem(position);
return mIdMap.get(item);
}
@Override
public boolean hasStableIds() {
return true;
}
}
}
Logcat は次のとおりです。
