java - 安卓资源$NotFoundException

Question

我正在创建一个应用程序，玩家可以在该应用程序中将自己的名字输入到编辑文本中。此信息被检索并通过 extras 发送到第二个 Activity 。每当我运行它时，我都会收到 Resources$NotFoundException。我很确定这是来 self 的代码还是来 self 的资源文件夹。

这是我的代码(更新后没有 TOAST 语句)

private void getNames(int number){      

    Intent intent = new Intent(Setup.this, Test.class);
    intent.putExtra("numberofplayers", number);

    try {

    if(!player1.getText().toString().contentEquals(""))
        p1 = player1.getText().toString();
    else
        p1= "Player 1";
    if(!player2.getText().toString().contentEquals(""))
        p2 = player2.getText().toString();
    else
        p2= "Player 2";
    if(!player3.getText().toString().contentEquals(""))
        p3 = player3.getText().toString();
    else
        p3= "Player 3";
    if(!player4.getText().toString().contentEquals(""))
        p4 = player4.getText().toString();
    else
        p5= "Player 5";
    if(!player6.getText().toString().contentEquals(""))
        p6 = player6.getText().toString();
    else
        p6= "Player 6";
    if(!player7.getText().toString().contentEquals(""))
        p7 = player7.getText().toString();
    else
        p7= "Player 7";
    if(!player8.getText().toString().contentEquals(""))
        p8 = player8.getText().toString();
    else
        p8= "Player 8";

    switch (number) {
    case 2:
        String[] a = {p1,p2};
        names=a;
        break;
    case 3:
        String[] b = {p1,p2,p3};
        names=b;
        break;
    case 4:
        String[] c = {p1,p2,p3,p4};
        names=c;
        break;
    case 5:
        String[] d= {p1,p2,p3,p4,p5};
        names=d;
        break;
    case 6:
        String[] e = {p1,p2,p3,p4,p5,p6};
        names=e;
        break;
    case 7:
        String[] f = {p1,p2,p3,p4,p5,p6,p7};
        names=f;
        break;
    case 8:
        String[] g = {p1,p2,p3,p4,p5,p6,p7,p8};
        names=g;
        break;
    }
    } catch (Exception e) {
        Log.e("Setup.class Error:", e.getMessage());
    }
    //Toast.makeText(this, number + "", Toast.LENGTH_SHORT).show();

    //for(int q =0;q<names.length;q++)
    //  Toast.makeText(this, names[q], Toast.LENGTH_SHORT).show();

    intent.putExtra("namearray", names);
    startActivity(intent);
}

这是接收 Activity 的代码:

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

    Bundle ext = getIntent().getExtras();
    int i= ext.getInt("numberofplayers");
    String[] names = ext.getStringArray("namearray");

    Toast.makeText(this, i, Toast.LENGTH_SHORT).show();

    for(int q =0;q<names.length;q++)
        Toast.makeText(this, names[q], Toast.LENGTH_SHORT).show();
}

这是 logcat 错误(更新的 LOGCAT 报告):

Answer 1

这是您的第一个 Toast 调用:

Toast.makeText(this, number, Toast.LENGTH_SHORT).show();

这里，第二个参数是一个整数(number)，所以它认为这是一个字符串 ID。尝试将 number 替换为 number+""。
