复制代码 代码如下:

/**

* 获取和保存当前屏幕的截图

*/

private void GetandSaveCurrentImage()

{

//1.构建Bitmap

WindowManager windowManager = getWindowManager();

Display display = windowManager.getDefaultDisplay();

int w = display.getWidth();

int h = display.getHeight();

Bitmap Bmp = Bitmap.createBitmap( w, h, Config.ARGB_8888 );

//2.获取屏幕

View decorview = this.getWindow().getDecorView();

decorview.setDrawingCacheEnabled(true);

Bmp = decorview.getDrawingCache();

String SavePath = getSDCardPath()+"/AndyDemo/ScreenImage";

//3.保存Bitmap

try {

File path = new File(SavePath);

//文件

String filepath = SavePath + "/Screen_1.png";

File file = new File(filepath);

if(!path.exists()){

path.mkdirs();

}

if (!file.exists()) {

file.createNewFile();

}

FileOutputStream fos = null;

fos = new FileOutputStream(file);

if (null != fos) {

Bmp.compress(Bitmap.CompressFormat.PNG, 90, fos);

fos.flush();

fos.close();

Toast.makeText(mContext, "截屏文件已保存至SDCard/AndyDemo/ScreenImage/下", Toast.LENGTH_LONG).show();

}

} catch (Exception e) {

e.printStackTrace();

}

}

/**

* 获取SDCard的目录路径功能

* @return

*/

private String getSDCardPath(){

File sdcardDir = null;

//判断SDCard是否存在

boolean sdcardExist = Environment.getExternalStorageState().equals(android.os.Environment.MEDIA_MOUNTED);

if(sdcardExist){

sdcardDir = Environment.getExternalStorageDirectory();

}

return sdcardDir.toString();

}

由于要对SDCard进行操作，所以别忘记了在manifest.xml文件中赋以对SDCard的读写权限：

<uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
