將else語句複製到if語句

Question

我試圖將else狀態的代碼複製到if語句中。 在這裏我看到if-eqz作爲if條件，但我不知道其他條件在這裏。有人可以幫我找到其他條件，以便我可以將它複製成if代碼。

我也想知道哪裏是起點和else語句體

goto :goto_1 

Answer 1

你的例子似乎不完全結束。例如它有goto :goto_0但不包含:goto_0標籤。無論如何，下面的例子應該可以幫助你弄清楚如何處理你的案例。 Smali如下代碼：

if-nez v0, :cond_0 

const-string v2, "hello 1" 

:goto_0 
return-void 

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

對應的Java代碼，如：

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

的goto語句和分支的確切位置取決於編譯器。此外，對於不同的情況，您可能會看到if-nez或if-eqz或其他一些聲明。
