将数组应用于其中的更改后，将数组传回主活动

String[] array = {"item1", "item2", "item3"};
Bundle bundle = new Bundle();
bundle.putStringArray("array", array);

Intent intent = new Intent(this, TargetActivity.class);
intent.putExtras(bundle);
startActivityForResult(intent, requestCode);

Intent intent = getIntent();
Bundle bundle = intent.getExtras();

String[] array = bundle.getStringArray("array");
array[0] = "modified item1";

Intent intent = new Intent();
intent.putExtras(bundle);
setResult(RESULT_OK, intent);
finish();

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    if (requestCode == requestCode && resultCode == RESULT_OK) {
        Bundle bundle = data.getExtras();
        String[] modifiedArray = bundle.getStringArray("array");
        // 处理修改后的数组数据
    }
}
