获取安卓模拟器截图
2025-12-02 01:14:48
最简单的方法当然是使用adb
adb shell screencap -p >screenshot.png
不过有些app会限制adb进行截图，这个时候adb截屏为黑屏
此时有两种方法获取截图
第一使用模拟器自带截图快捷键,获取安卓自带截图键，逍遥模拟器为alt+F3
可模拟键盘输入按键（自行百度）
第二种：使用winapi + 电脑屏幕截图
以下为C#代码，python请自行转换（memu为逍遥模拟器的窗口名称）
先获取模拟器句柄，然后使窗口显示，根据窗口大小和位置截图，然后隐藏窗口
///

public static Bitmap GetEmulatorScreen(int num)
{
Process[] procList = Process.GetProcessesByName("memu");
for (int i = 0; i < 20; i++)
{
if (i == num)
{
IntPtr handle = procList[i].MainWindowHandle;
ShowWindow(handle, 1);
RECT rECT = new RECT();
GetWindowRect(handle, ref rECT);
Task.Delay(200).Wait();
Bitmap bitmap = ScreenShot.GetScreen(rECT.Left, rECT.Top, rECT.Right, rECT.Bottom);
ShowWindow(handle, 2);
return bitmap;
}
}
return null;
}
