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"/>
