这是一个smali代码，可从数据库文件中的"weblink"返回标题和链接.我想返回一个静态值(例如'This is the link www.google.com')，而不是数据库文件中的Title和Link.我怎样才能做到这一点?我应该更改什么代码?这类似于这里的问题(如何返回静态结果在smali函数中)，我已经尝试了该解决方案.但是应用程序正在强制关闭.有人可以帮忙吗?
This is a smali code which returns a Title and a Link from 'weblink' inside a database file. I want to return a static value (example 'This is the link www.google.com ' ) instead of Title and Link from database file. How can I do that? What code should I change? This is similar to this question here ( How to return a static result in smali function ) and I already tried that solution. But app is force closing. can somebody help?
推荐答案
在将字符串对象附加到StringBuilder之前，只需重写它的内容.
Simply override the content of the string object before it's appended to the StringBuilder.
.line 304
invoke-virtual {v0}, Lcom/myapp/data/weblink;->getTitle()Ljava/lang/String;
move-result-object v4
# Add following line to override v4 before it's appended to the StringBuilder
const-string v4, "This is the link"
invoke-virtual {v3, v4}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;
类似地，您可以对链接执行相同的操作
Similarly, you can do the same for the link
invoke-virtual {v0}, Lcom/myapp/data/weblink;->getLink()Ljava/lang/String;
move-result-object v0
invoke-virtual {v0}, Ljava/lang/String;->toString()Ljava/lang/String;
move-result-object v0
# Add following line to override v0 before it's appended to the StringBuilder
const-string v0, "www.google.com"
invoke-virtual {v3, v0}, Ljava/lang/StringBuilder;->append(Ljava/lang/String;)Ljava/lang/StringBuilder;
实际上，您可以在将整个字符串放入意图之前立即覆盖整个字符串.
Actually, you can override the whole string at once before it's put to the intent.
invoke-virtual {v0}, Ljava/lang/StringBuilder;->toString()Ljava/lang/String;
move-result-object v0
# Add this line
const-string v0, "The whole text you want, including the title and link"
.line 303
invoke-virtual {v1, v2, v0}, Landroid/content/Intent;->putExtra(Ljava/lang/String;Ljava/lang/String;)Landroid/content/Intent;
:try_end_0
.catch Ljava/lang/Exception; {:try_start_0 .. :try_end_0} :catch_0
我希望你没有做不好的事情.
I hope you are not doing something bad.
