我有一个应用程序，目前使用相机拍摄图像，此刻一旦图像被保存到SD卡上的文件夹，然后同一屏幕保持所以可以拍摄另一张照片。Android意图打开带图片的新屏幕
我想要它，所以当图像已被采取和保存一个新的屏幕打开与新屏幕上的图片。
我已经制作了一个新的xml文件punch.xml和java Punch.java并将它们注册到清单中我只是无法弄清楚如何设置应用程序以打开刚刚拍摄的图片的新屏幕。
我猜这是一旦图像被保存后打开新的Intent。
更新
确定，所以所有的工作现在execpt获得的图像显示在下一屏幕上？
Punch.java
@Override
protected void onCreate(Bundle savedInstanceState) {
// TODO Auto-generated method stub
super.onCreate(savedInstanceState);
setContentView(R.layout.punch);

UPDATE
望着建议使用putExtra（）怎么办我设置和检索这个值？
'getIntent（）getStringExtra（）来的setResult;' – Merlin 2011-12-22 13:41:26
获得如上，如果你正在使用Eclipse和Android插件它应该表现出你putExtra工具提示（字符串名称，对象在这里）;所以它会像intent.putExtra（“filepath”，new String（Environment.getExternalStorageDirectory（）+“/ image.jpg”）或任何字符串到您的文件位置。然后，正如Merlin在新的新的活动你打电话的意图，以获得您可以在您的活动中使用的值，如：this.getIntent（）。getStringExtra（filepath）; – Davos555 2011-12-22 14:25:10
@ Davos555我有点得到你的意思，但仍然不知道如何实现可以你用新的代码更新你的答案？ – Matt 2011-12-22 14:32:59
