사진 저장 (핸드폰 호출), 대화 상자 사용자 정의 스타일

홈 페이지 레이아웃 파일 은 간단 합 니 다. 단추 팝 업 대화 상자 입 니 다. imageView 는 선택 한 그림 을 표시 합 니 다.
나 는 모두 에 게 다운로드 코드 를 제공 했다.
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="    " 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> 

팝 업 대화 상 자 는 두 개의 단추 입 니 다. 하 나 는 사진 을 찍 는 것 이 고, 하 나 는 앨범 에서 사진 을 추출 하 는 것 입 니 다.
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> 

먼저 주요 코드 를 드 리 겠 습 니 다.

클릭 모듈 1

//------------------------------------------------------------------------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); //        

            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); } }); //        

            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); } }); } }

대화 상자 스타일 을 설정 하고 대화 상자 테 두 리 를 제거 합 니 다.

 final Dialog dialog = new Dialog(MyDialogDemo.this, R.style.dialog); dialog.setContentView(myView); dialog.show();

안에 R. style. dialog 사용자 정의 style 에 있 습 니 다.

<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>

리 턴 방법 모듈 2

@Override protected void onActivityResult(int requestCode, int resultCode, Intent data) { // TODO Auto-generated method stub

        if (resultCode == NONE) return; //   

        if (requestCode == PHOTO_GRAPH) { //         

            File picture = new File(Environment.getExternalStorageDirectory() + "/temp.jpg"); startPhotoZoom(Uri.fromFile(picture)); } if (data == null) return; //         

        if (requestCode == PHOTO_ZOOM) { startPhotoZoom(data.getData()); } //     

        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)     //     Bitmap   sd  ，    ：http://www.cnblogs.com/linjiqin/archive/2011/12/28/2304940.html

                imageView.setImageBitmap(photo); //      ImageView   

 } } super.onActivityResult(requestCode, resultCode, data); }

 
수축 사진 모듈 3 (휴대 전화 에 작은 아이콘 표시 편리)
 

/** *      * * @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       

        intent.putExtra("aspectX", 1); intent.putExtra("aspectY", 1); // outputX outputY        

        intent.putExtra("outputX", 300); intent.putExtra("outputY", 500); intent.putExtra("return-data", true); startActivityForResult(intent, PHOTO_RESOULT); }
