方法一:
在APK中调用“adb shellscreencap -pfilepath” 命令
该命令读取系统的framebuffer,需要获得系统权限:
(1).在AndroidManifest.xml文件中添加
<uses-permissionandroid:name="android.permission.READ_FRAME_BUFFER"/>
(2).修改APK为系统权限,将APK放到源码中编译, 修改Android.mk
LOCAL_CERTIFICATE:= platform
public void takeScreenShot(){
String mSavedPath = Environment.getExternalStorageDirectory() + File.separator + "screenshot.png" ;
try {
Runtime. getRuntime().exec("screencap -p " + mSavedPath);
} catch (Exception e) {
e.printStackTrace();
}
方法二:
利用系统的API,实现Screenshot,这部分代码是系统隐藏的,需要在源码下编译,
(1).在AndroidManifest.xml文件中添加
<uses-permissionandroid:name="android.permission.READ_FRAME_BUFFER"/>
(2).修改APK为系统权限,将APK放到源码中编译, 修改Android.mk
LOCAL_CERTIFICATE:= platform
public boolean takeScreenShot(String imagePath){
if(imagePath.equals("" )){
imagePath = Environment.getExternalStorageDirectory() + File.separator+"Screenshot.png";
}
Bitmap mScreenBitmap;
WindowManager mWindowManager;
DisplayMetrics mDisplayMetrics;
Display mDisplay;
mWindowManager = (WindowManager) mcontext.getSystemService(Context.WINDOW_SERVICE);
mDisplay = mWindowManager.getDefaultDisplay();
mDisplayMetrics = new DisplayMetrics();
mDisplay.getRealMetrics(mDisplayMetrics);
float[] dims = {mDisplayMetrics.widthPixels , mDisplayMetrics.heightPixels };
mScreenBitmap = Surface. screenshot((int) dims[0], ( int) dims[1]);
if (mScreenBitmap == null) {
return false ;
}
try {
FileOutputStream out = new FileOutputStream(imagePath);
mScreenBitmap.compress(Bitmap.CompressFormat. PNG, 100, out);
} catch (Exception e) {
return false ;
}
return true ;
}
