如何获取我使用intent打开的活动的引用？

Intent intent = new Intent(this, TargetActivity.class);
startActivityForResult(intent, REQUEST_CODE);

Intent intent = getIntent();

Intent resultIntent = new Intent();
resultIntent.putExtra("key", data);
setResult(RESULT_OK, resultIntent);
finish();

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    super.onActivityResult(requestCode, resultCode, data);
    
    if (requestCode == REQUEST_CODE && resultCode == RESULT_OK) {
        // 获取目标活动的引用
        Activity targetActivity = this;
        
        // 获取返回的数据
        String returnedData = data.getStringExtra("key");
        
        // 在这里可以对返回的数据进行处理
    }
}
