拍照保存（调用手机），对话框的自定义样式
主页面布局文件很简单就是一个按钮弹出对话框，一个imageView显示选择的图片。
我给大家提供了下载代码在这个网页：http://download.csdn.net/download/u011348453/7669871
main.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:orientation="vertical" android:layout_width="fill_parent" android:layout_height="fill_parent"> <Button android:id="@+id/mybut" android:text="用户登录" android:layout_width="wrap_content" android:layout_height="wrap_content"/> <ImageView android:id="@+id/img_photo" android:layout_width="wrap_content" android:layout_height="wrap_content" /></LinearLayout> 弹出对话框是两个按钮，一个是拍照，一个是从相册中提取照片。
photo.xml
<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="#ffffff" android:gravity="center_vertical" android:orientation="vertical"> <ImageButton android:id="@+id/img_takephoto" android:layout_marginLeft="15dip" android:layout_marginTop="20dip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/a_takephoto" /> <ImageView android:layout_margin="10dip" android:layout_width="240dip" android:layout_height="2dip" android:background="#CACDCF" /> <ImageButton android:id="@+id/img_getphoto" android:layout_marginLeft="15dip" android:layout_marginBottom="20dip" android:layout_width="wrap_content" android:layout_height="wrap_content" android:background="@drawable/a_localphoto" /></LinearLayout> 先给出主要的代码

//------------------------------------------------------------------------1 private class OnClickListenerImpl implements OnClickListener { @Override public void onClick(View view) { LayoutInflater factory = LayoutInflater.from(MyDialogDemo.this); View myView = factory.inflate(R.layout.a_login, null);// final Dialog dialog = new AlertDialog.Builder(MyDialogDemo.this)// .setView(myView).create();// dialog.show(); final Dialog dialog = new Dialog(MyDialogDemo.this, R.style.dialog); dialog.setContentView(myView); dialog.show(); takephoto = (ImageButton) myView.findViewById(R.id.img_takephoto); getphoto = (ImageButton) myView.findViewById(R.id.img_getphoto); // 从拍照获取图片 takephoto.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Log.d("MyDialogDemo", "sslfjsljls"); Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE); intent.putExtra( MediaStore.EXTRA_OUTPUT, Uri.fromFile(new File(Environment .getExternalStorageDirectory(), "temp.jpg"))); dialog.dismiss(); startActivityForResult(intent, PHOTO_GRAPH); } }); // 从相册获取图片 getphoto.setOnClickListener(new OnClickListener() { @Override public void onClick(View v) { // TODO Auto-generated method stub Intent intent = new Intent(Intent.ACTION_PICK, null); intent.setDataAndType( MediaStore.Images.Media.EXTERNAL_CONTENT_URI, IMAGE_UNSPECIFIED); dialog.dismiss(); startActivityForResult(intent, PHOTO_ZOOM); } }); } }这里设置对话框样式，去掉对话框边框
final Dialog dialog = new Dialog(MyDialogDemo.this, R.style.dialog); dialog.setContentView(myView); dialog.show();里面的R.style.dialog自定义在style里
<resources xmlns:android="http://schemas.android.com/apk/res/android"> <style name="dialog" parent="@android:style/Theme.Dialog"> <item name="android:windowFrame">@null</item> <item name="android:windowIsFloating">true</item> <item name="android:windowIsTranslucent">false</item> <item name="android:windowNoTitle">true</item> <item name="android:background">@android:color/black</item> <item name="android:windowBackground">@null</item> <item name="android:backgroundDimEnabled">false</item> </style></resources>回调方法模块2
@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub if (resultCode == NONE) return; // 拍照 if (requestCode == PHOTO_GRAPH) { // 设置文件保存路径 File picture = new File(Environment.getExternalStorageDirectory() + "/temp.jpg"); startPhotoZoom(Uri.fromFile(picture)); } if (data =http://www.mamicode.com/= null) return; // 读取相册缩放图片 if (requestCode == PHOTO_ZOOM) { startPhotoZoom(data.getData()); } // 处理结果 if (requestCode == PHOTO_RESOULT) { Bundle extras = data.getExtras(); if (extras != null) { Bitmap photo = extras.getParcelable("data"); ByteArrayOutputStream stream = new ByteArrayOutputStream(); photo.compress(Bitmap.CompressFormat.JPEG, 75, stream);// (0-100)压缩文件 //此处可以把Bitmap保存到sd卡中，具体请看：http://www.cnblogs.com/linjiqin/archive/2011/12/28/2304940.html imageView.setImageBitmap(photo); //把图片显示在ImageView控件上 } } super.onActivityResult(requestCode, resultCode, data); }
收缩图片模块3（方便手机显示小图标）
/** * 收缩图片 * * @param uri */ public void startPhotoZoom(Uri uri) { Intent intent = new Intent("com.android.camera.action.CROP"); intent.setDataAndType(uri, IMAGE_UNSPECIFIED); intent.putExtra("crop", "true"); // aspectX aspectY 是宽高的比例 intent.putExtra("aspectX", 1); intent.putExtra("aspectY", 1); // outputX outputY 是裁剪图片宽高 intent.putExtra("outputX", 300); intent.putExtra("outputY", 500); intent.putExtra("return-data", true); startActivityForResult(intent, PHOTO_RESOULT); }
