Question

我正在尝试将else状态的代码复制到if语句中。在这里，我看到if-eqz作为if条件，但我不知道其他条件在哪里。有人可以帮我找到其他条件，以便我可以复制它成为if代码。

我也想知道else语句体的起点和终点在哪里

goto :goto_1

Answer 1

你的例子似乎不完整。例如，它有goto :goto_0但不包含:goto_0标签。无论如何，以下示例应该可以帮助您弄清楚如何处理您的案例。 Smali代码如下：

if-nez v0, :cond_0

const-string v2, "hello 1"

:goto_0
return-void

:cond_0
const-string v2, "hello 2"
goto :goto_0

对应于Java代码：

if (i == 0) {
    s = "hello 1";
}
else {
    s = "hello 2";
}
return;

goto语句和分支的确切位置取决于编译器。另外，对于不同的情况，您可能会看到if-nez或if-eqz或其他一些陈述。
