我的想要的是每當我使用setPart_no的時候 他會丟一筆資料到陣列 可是我列印解果出來 都只會有最後一筆 求解
寫入

public class GlobalVariable extends Application {
    private String part_no;
    private String user_id;         //User 密碼
    private String[] part;
    
    public String[] getPart() {
        return part;
    }
    public String getPart_no() {
        return part_no;
    }
    public void setPart_no(String part_no) {
        this.part_no = part_no;
         part = new String[]{part_no};
    }
    public String getUser_id() {
        return user_id;
    }
    public void setUser_id(String user_id) {
        this.user_id = user_id;
    }
}

接收

 GlobalVariable Account = (GlobalVariable)getApplicationContext();
        tests = Account.getPart();
        test.setText(Arrays.toString(tests));
