Question

我想在我的主要活动中为startActivityForResult

制作两个按钮

每当我按下其中任何一个按钮，我的应用程序强制关闭，我无法弄清楚原因！

以下是两个按钮的代码：

public void billiards (View v)
{

    Intent billiards = new Intent(this,Billiards.class);

    startActivityForResult(billiards,99710);

}



public void snooker (View v)
{

    Intent snooker = new Intent(this,Snooker.class);

    startActivityForResult(snooker,99711);



}

以下是Billiards活动的代码：

public void bsave (View v)
{

    Double dbgames = Double.parseDouble(ebgames.getText().toString());
    Double calcbgames = (dbgames)*0.50;

    Double btotal = (calcbgames);


    Intent billiards=new Intent();
    billiards.putExtra("btot",String.valueOf(btotal));
    setResult(99710,billiards);
    finish();

}

以下是Snooker活动的代码：

public void ssave (View v)
{

    Double dsgames = Double.parseDouble(esgames.getText().toString());
    Double calcsgames = (dsgames)*1.00;

    Double stotal = (calcsgames);


    Intent snooker=new Intent();
    snooker.putExtra("stot",String.valueOf(stotal));
    setResult(99710,snooker);
    finish();

}

以下是我onActivityResult中的MainActivity代码：

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode==99710) {
        if (resultCode == RESULT_OK) {
            String billiardstot = data.getStringExtra("btot");

            String bt = billiardstot;

            SharedPreferences.Editor editor = sharedpreferences.edit();

            editor.putString(BToatal, bt);

            editor.commit();


        } else if (resultCode == RESULT_CANCELED) {
            Toast.makeText(getApplicationContext(), "Wrong Request Code", Toast.LENGTH_LONG).show();
        }
    }

    if (requestCode==99711) {
        if (resultCode == RESULT_OK) {

            String snookertot = data.getStringExtra("stot");

            String st = snookertot;

            SharedPreferences.Editor editor = sharedpreferences.edit();

            editor.putString(STotal, st);

            editor.commit();


        } else if (resultCode == RESULT_CANCELED) {
            Toast.makeText(getApplicationContext(), "Wrong Result Code", Toast.LENGTH_LONG).show();
        }

    }

}

每当我按下Billiards或Snooker按钮时，应用程序强制关闭

这是LogCat：

您requestCode使用的值太大

坚持小于65535的东西
