java - 为表动态创建表行

Question

我正在尝试根据设备 SD 卡上存储的数据填充我的游戏的高分表。

这是我的LeaderboardActivity.java:

public class LeaderboardActivity extends Activity {
private Leaderboard leaderboard;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_leaderboard);

    TableLayout highscoresTable = (TableLayout) findViewById(R.id.highscoresTable);
    this.leaderboard = new Leaderboard();

    ArrayList<Player> players = leaderboard.getScores();
    if(!(players==null))
    {
        Collections.sort(players);

        for(Player p:players)
        {
            TableRow newRow = new TableRow(this);
            TextView name = new TextView(this);
            TextView time = new TextView(this);

            name.setText(p.getName());
            name.setGravity(Gravity.CENTER_VERTICAL);
            name.setPadding(15, 0, 15, 0);
            time.setText(p.getTime());
            time.setGravity(Gravity.CENTER_VERTICAL);
            time.setPadding(15, 0, 15, 0);

            newRow.addView(name);
            newRow.addView(time);
            highscoresTable.addView(newRow);
        }
        setContentView(highscoresTable);
    }
    else
    {
        Log.i("DEBUG", "players is equal to null!");
    }
}

@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_leaderboard, menu);
    return true;
}
}

这是我的 XML activity_leaderboard.xml:

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@color/background"
android:orientation="horizontal" >

<TableLayout
    android:id="@+id/highscoresTable"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:padding="15dp" >

    <TableRow
        android:id="@+id/headerRow"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:gravity="center_vertical|fill_horizontal"
        android:showDividers="middle" >

        <TextView
            android:text="NAME"
            android:gravity="center_vertical"
            android:padding="15dp">
        </TextView>

        <TextView
            android:gravity="center_horizontal|center_vertical"
            android:padding="15dp"
            android:text="TIME" />

    </TableRow>

    <TableRow
        android:id="@+id/testRow"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" >

        <TextView
            android:text="TEST"
            android:gravity="center_vertical"
            android:paddingLeft="15dp"
            android:paddingRight="15dp">
        </TextView>

        <TextView
            android:gravity="center_horizontal|center_vertical"
            android:paddingLeft="15dp"
            android:paddingRight="15dp"
            android:text="NOT REAL" />

    </TableRow>


</TableLayout>

</LinearLayout>

出于某种原因，当我运行排行榜时，它会导致 RuntimeException

我怎样才能让它工作？

Answer 1

您的p.getTime()方法返回一个int。将此 int 值与 setText() 一起使用将使 TextView 认为您正在使用引用 string< 的 id 设置文本 资源很可能不是这种情况。而是使用:

time.setText(String.valueOf(p.getTime()));
