だから私は、ユーザー入力からコードを取り込んでリストビューのカスタムレイアウトに入れるアンドロイドアプリを構築しようとしています。
リストの各要素に対して持っているレイアウトのxmlは次のとおりです（以下はgame_row.xmlと呼ばれます）
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical" >
<TextView
android:id="@+id/dateout"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="@+id/team1out"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/dateout"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="@+id/team2out"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_below="@+id/team1out"
android:text="Large Text"
android:textAppearance="?android:attr/textAppearanceLarge" />
<TextView
android:id="@+id/score1out"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_above="@+id/team2out"
android:layout_alignParentRight="true"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<TextView
android:id="@+id/score2out"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignBottom="@+id/team2out"
android:layout_alignParentRight="true"
android:text="Medium Text"
android:textAppearance="?android:attr/textAppearanceMedium" />
<View
android:layout_width="fill_parent"
android:layout_below="@+id/team2out"
android:layout_height="1dp"
android:background="@android:color/white"/>
</RelativeLayout>
そして、これが私のクラスのJavaコードです:
public class KeepScoreHomeScreen extends Activity {
ArrayList<Game> Game_data = new ArrayList<Game>();
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.home_screen);
if (savedInstanceState != null) {
System.out.println("this shouldnt happen");
ArrayList<Game> inp = (ArrayList<Game>) savedInstanceState.get("games");
System.out.println("game made");
Game_data.addAll(inp);
}
// System.out.println("helo");
// Game_data.add(new Game(1,2,3,4,3, "t","T"));
GameAdapter adapter = new GameAdapter(this, R.layout.game_row, Game_data);
// This is used to update the maximum number of days in a month
Bundle extras = getIntent().getExtras();
ListView gameList = (ListView) findViewById(R.id.main_list_view);
gameList.setAdapter(adapter);
}
@Override
public void onSaveInstanceState(Bundle savedInstanceState) {
super.onSaveInstanceState(savedInstanceState);
savedInstanceState.putParcelableArrayList("games", Game_data);
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.activity_home_menu, menu);
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
// Handle item selection
switch (item.getItemId()) {
case R.id.action_newEntry:
toNewEntry(this.findViewById(R.layout.home_screen));
break;
case R.id.action_help:
buildHelp(this.findViewById(R.layout.home_screen));
break;
case R.id.action_settings:
buildSettings(this.findViewById(R.layout.home_screen));
default:
return super.onOptionsItemSelected(item);
}
return false;
}
public void toNewEntry(View view) {
Intent intent = new Intent(this, KeepScoreActivity.class);
startActivityForResult(intent, 1);
}
protected void onActivityResult(int r, int j, Intent intent) {
// System.out.println("hedslo");
Bundle bundle = intent.getBundleExtra("myfirstintent");
int sc1 = bundle.getInt("score1");
int sc2 = bundle.getInt("score2");
int ye = bundle.getInt("year");
int mo = bundle.getInt("month");
int da = bundle.getInt("day");
String te1 = bundle.getString("team1");
String te2 = bundle.getString("team2");
Game g = new Game(sc1, sc2, ye, mo, da, te1, te2);
Game_data.add(g);
GameAdapter adapter = new GameAdapter(this, R.layout.game_row, Game_data);
ListView gameList = (ListView) findViewById(R.id.main_list_view);
gameList.setAdapter(adapter);
}
public void buildHelp(View view) {
/***
* this code to build an alert dialog was taken from
* http://stackoverflow
* .com/questions/2795300/how-to-implement-a-custom-alertdialog-view
*
* I used this code because it allowed me to insert a simple xml file as
* my alertdialog
*
*/
LayoutInflater inflater = getLayoutInflater();
View dialoglayout = inflater.inflate(R.layout.help_layout, (ViewGroup) getCurrentFocus());
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(dialoglayout);
builder.show();
}
public void buildSettings(View view) {
LayoutInflater inflater = getLayoutInflater();
View dialoglayout = inflater.inflate(R.layout.settings_layout, (ViewGroup) getCurrentFocus());
AlertDialog.Builder builder = new AlertDialog.Builder(this);
builder.setView(dialoglayout);
builder.show();
}
}
私が抱えている問題は、game_row出力を作成してから設定バーを膨らませようとするたびに、次のエラーが発生することです

誰かが私のビューを互いにうまくプレイさせる方法を理解するのを手伝ってもらえますか?
