android开发(15) 调用摄像头拍照，保存在照片到数据库。
好吧。我们做手机开发的，总是避免不了操作摄像头的问题。我在这里也纠结了一天。只好不停的再搜索引擎里搜来搜去。最后做了一个完整示例。期间遇到很多问题，把自己折磨的不行。那么弄个完整的示例，给自己，也给后来学习者。那么，开始说代码吧。
1。启动摄像头
//向 MediaStore.Images.Media.EXTERNAL_CONTENT_URI 插入一个数据，那么返回标识ID。
//在完成拍照后，新的照片会以此处的photoUri命名. 其实就是指定了个文件名
ContentValues values = new ContentValues();
photoUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
//准备intent，并 指定 新 照片 的文件名（photoUri）
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, photoUri);
//启动拍照的窗体。并注册 回调处理。
startActivityForResult(intent, REQUEST_CODE_camera);
//在完成拍照后，新的照片会以此处的photoUri命名. 其实就是指定了个文件名
ContentValues values = new ContentValues();
photoUri = getContentResolver().insert(
MediaStore.Images.Media.EXTERNAL_CONTENT_URI, values);
//准备intent，并 指定 新 照片 的文件名（photoUri）
Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
intent.putExtra(android.provider.MediaStore.EXTRA_OUTPUT, photoUri);
//启动拍照的窗体。并注册 回调处理。
startActivityForResult(intent, REQUEST_CODE_camera);
2. 处理 回调。就是当拍照完成后，我们如何处理它。我们必须在activity的onActivityResult（要重载此方法）方法里处理它。
public void HandleonActivityResult(int requestCode, int resultCode,
Intent data) {
if (requestCode == CameraHelper.REQUEST_CODE_camera) {
ContentResolver cr = mContext.getContentResolver();
if (photoUri == null)
return;
//按 刚刚指定 的那个文件名，查询数据库，获得更多的 照片信息，比如 图片的物理绝对路径
Cursor cursor = cr.query(photoUri, null, null, null, null);
if (cursor != null) {
if (cursor.moveToNext()) {
String path = cursor.getString(1);
//获得图片
Bitmap bp = getBitMapFromPath(path);
imageView1.setImageBitmap(bp);
//写入到数据库
mBlobDAL.InsertImg(bp);
}
cursor.close();
}
photoUri = null;
}
Intent data) {
if (requestCode == CameraHelper.REQUEST_CODE_camera) {
ContentResolver cr = mContext.getContentResolver();
if (photoUri == null)
return;
//按 刚刚指定 的那个文件名，查询数据库，获得更多的 照片信息，比如 图片的物理绝对路径
Cursor cursor = cr.query(photoUri, null, null, null, null);
if (cursor != null) {
if (cursor.moveToNext()) {
String path = cursor.getString(1);
//获得图片
Bitmap bp = getBitMapFromPath(path);
imageView1.setImageBitmap(bp);
//写入到数据库
mBlobDAL.InsertImg(bp);
}
cursor.close();
}
photoUri = null;
}
3.我们在这里需要处理图片的缩放。以为图片太大了，直接放入ImageView是无法显示的。
/* 获得图片，并进行适当的 缩放。 图片太大的话，是无法展示的。 */
private Bitmap getBitMapFromPath(String imageFilePath) {
Display currentDisplay = getWindowManager().getDefaultDisplay();
int dw = currentDisplay.getWidth();
int dh = currentDisplay.getHeight();
// Load up the image's dimensions not the image itself
BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
bmpFactoryOptions.inJustDecodeBounds = true;
Bitmap bmp = BitmapFactory.decodeFile(imageFilePath,
bmpFactoryOptions);
int heightRatio = (int) Math.ceil(bmpFactoryOptions.outHeight
/ (float) dh);
int widthRatio = (int) Math.ceil(bmpFactoryOptions.outWidth
/ (float) dw);
// If both of the ratios are greater than 1,
// one of the sides of the image is greater than the screen
if (heightRatio > 1 && widthRatio > 1) {
if (heightRatio > widthRatio) {
// Height ratio is larger, scale according to it
bmpFactoryOptions.inSampleSize = heightRatio;
} else {
// Width ratio is larger, scale according to it
bmpFactoryOptions.inSampleSize = widthRatio;
}
}
// Decode it for real
bmpFactoryOptions.inJustDecodeBounds = false;
bmp = BitmapFactory.decodeFile(imageFilePath, bmpFactoryOptions);
return bmp;
}
int dw = currentDisplay.getWidth();
int dh = currentDisplay.getHeight();
// Load up the image's dimensions not the image itself
BitmapFactory.Options bmpFactoryOptions = new BitmapFactory.Options();
bmpFactoryOptions.inJustDecodeBounds = true;
Bitmap bmp = BitmapFactory.decodeFile(imageFilePath,
bmpFactoryOptions);
int heightRatio = (int) Math.ceil(bmpFactoryOptions.outHeight
/ (float) dh);
int widthRatio = (int) Math.ceil(bmpFactoryOptions.outWidth
/ (float) dw);
// If both of the ratios are greater than 1,
// one of the sides of the image is greater than the screen
if (heightRatio > 1 && widthRatio > 1) {
if (heightRatio > widthRatio) {
// Height ratio is larger, scale according to it
bmpFactoryOptions.inSampleSize = heightRatio;
} else {
// Width ratio is larger, scale according to it
bmpFactoryOptions.inSampleSize = widthRatio;
}
}
// Decode it for real
bmpFactoryOptions.inJustDecodeBounds = false;
bmp = BitmapFactory.decodeFile(imageFilePath, bmpFactoryOptions);
return bmp;
}
好了。处理摄像头拍照是完了。下面我们要把图片存放在数据里。
4.建表
@Override
publicvoid onCreate(SQLiteDatabase db) {
String str = "CREATE TABLE [IMGS] ( [IDPK] integer PRIMARY KEY autoincrement,IMG_DATA blob )";
db.execSQL(str);
}
db.execSQL(str);
}
5.插入数据库。
/** 插入图
* */
public void InsertImg(Bitmap bmp) {
SQLiteDatabase db = getWritableDatabase();
ContentValues cv = new ContentValues();
ByteArrayOutputStream os = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, os);
cv.put("IMG_DATA", os.toByteArray());
db.insert("IMGS", null, cv);
}
public void InsertImg(Bitmap bmp) {
SQLiteDatabase db = getWritableDatabase();
ContentValues cv = new ContentValues();
ByteArrayOutputStream os = new ByteArrayOutputStream();
bmp.compress(Bitmap.CompressFormat.PNG, 100, os);
cv.put("IMG_DATA", os.toByteArray());
db.insert("IMGS", null, cv);
}
6.读取图片列表
//读取
public List<Bitmap> ReadImg() {
SQLiteDatabase db = getReadableDatabase();
Cursor cr = db.rawQuery("select * from IMGS ", null);
List<Bitmap> lst = new ArrayList<Bitmap>();
while (cr.moveToNext()) {
byte[] in = cr.getBlob(cr.getColumnIndex("IMG_DATA"));
lst.add(BitmapFactory.decodeByteArray(in, 0, in.length));
}
return lst; }
public List<Bitmap> ReadImg() {
SQLiteDatabase db = getReadableDatabase();
Cursor cr = db.rawQuery("select * from IMGS ", null);
List<Bitmap> lst = new ArrayList<Bitmap>();
while (cr.moveToNext()) {
byte[] in = cr.getBlob(cr.getColumnIndex("IMG_DATA"));
lst.add(BitmapFactory.decodeByteArray(in, 0, in.length));
}
return lst; }
