看來，你沒有把你的Bundle放在Intent對象里面。
String bread = sendET.getText().toString();
Bundle basket = new Bundle();
basket.putString("key", bread);
Intent a = new Intent(Data.this,OpenedClass.class);
a.putExtras(basket);//set your bundle inside intent
startActivity(a);
Bundle gotBasket = getIntent().getExtras();
gotBread = gotBasket.getString("key");
gotBasket為null，因為在啟動活動時沒有傳遞任何額外內容。
試試這個：在Data.java中
Intent a = new Intent(Data.this,OpenedClass.class);
a.putExtra("key", bread);
在OpenedClass.java中：
Bundle gotBasket = getIntent().getExtras();
gotBread = gotBasket.getString("key");
你可以上傳錯誤日志然后很容易解決問題。
在mainfest中聲明OpenedClass。
