<Button android:id="@+id/btn_jp" android:layout_marginTop="10dip" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:text="截屏" android:textColor="#ff999999" /><Button android:id="@+id/btn_share" android:layout_marginTop="10dip" android:layout_width="match_parent" android:layout_height="wrap_content" android:gravity="center" android:text="分享" android:textColor="#ff999999" />

private String imagePath;//截屏  btnJp.setOnClickListener(new View.OnClickListener() {   @Override   public void onClick(View v) {//    image = ScreenShot.shoot(AddressSelecterActivity.this);    screenshot();//    Bitmap bitmap = getBitmapByView(scrollView);//    savePic(bitmap);   }  });  //分享  btnShare.setOnClickListener(new View.OnClickListener() {   @Override   public void onClick(View v) {    if (imagePath != null){     Intent intent = new Intent(Intent.ACTION_SEND); // 启动分享发送的属性     File file = new File(imagePath);     intent.putExtra(Intent.EXTRA_STREAM, Uri.fromFile(file));// 分享的内容     intent.setType("image/*");// 分享发送的数据类型     Intent chooser = Intent.createChooser(intent, "Share screen shot");     if(intent.resolveActivity(getPackageManager()) != null){      startActivity(chooser);     }    } else {     Toast.makeText(AddressSelecterActivity.this, "先截屏，再分享", Toast.LENGTH_SHORT).show();    }   }  });

//截取屏幕的方法private void screenshot() { // 获取屏幕 View dView = getWindow().getDecorView(); dView.setDrawingCacheEnabled(true); dView.buildDrawingCache(); Bitmap bmp = dView.getDrawingCache(); if (bmp != null) {  try {   // 获取内置SD卡路径   String sdCardPath = Environment.getExternalStorageDirectory().getPath();   // 图片文件路径   imagePath = sdCardPath + File.separator + "screenshot.png";   File file = new File(imagePath);   FileOutputStream os = new FileOutputStream(file);   bmp.compress(Bitmap.CompressFormat.PNG, 100, os);   os.flush();   os.close();  } catch (Exception e) {  } }}
