我正在爲客戶創建應用程序存儲他們的圖像和詳細信息。我正在通過相機或SD卡瀏覽圖像。我通過sdcard獲取ImageView
中的圖像,但是當我將它插入數據庫時,它不插入數據庫中的圖像列。我從SD卡獲取圖像並在imageview上顯示它現在我想將此圖像插入數據庫,但未將其存儲在數據庫中
我點擊SD卡按鈕瀏覽圖像。現在這個圖像顯示在ImageView
。
Button btnsdcard = (Button) findViewById(R.id.custbtnimage);
btnsdcard.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(
Intent.ACTION_PICK,
android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, ACTIVITY_SELECT_IMAGE);
}
});
@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
// TODO Auto-generated method stub
super.onActivityResult(requestCode, resultCode, data);
switch (requestCode) {
case 1:
if (resultCode == RESULT_OK) {
Uri selectedImage = data.getData();
try {
InputStream imgstream = getContentResolver()
.openInputStream(selectedImage);
Bitmap btm = BitmapFactory.decodeStream(imgstream);
ImageView img = (ImageView) findViewById(R.id.imagecust);
img.setImageBitmap(btm);
ByteArrayOutputStream bo = new ByteArrayOutputStream();
btm.compress(Bitmap.CompressFormat.PNG, 100, bo);
byte[] custimage = bo.toByteArray();
} catch (FileNotFoundException e) {
e.printStackTrace();
Toast.makeText(getBaseContext(), "file not fount",
Toast.LENGTH_SHORT).show();
}
} }
}
現在當我點擊保存按鈕其他數據存儲在數據庫中但圖像列在數據庫中爲空,我沒有得到任何錯誤。
btnsave.setOnClickListener(new OnClickListener() {
@SuppressLint("ParserError")
public void onClick(View v) {
// TODO Auto-generated method stub
String name = custname.getText().toString();
String address = custaddress.getText().toString();
Long pincode = Long.parseLong(custpincode.getText().toString());
String city = custcity.getText().toString();
byte[] image=custimage;
Customerprofile profile = new Customerprofile();
profile.setName(name);
profile.setAddress(address);
profile.setPincode(pincode);
profile.setCity(city);
profile.setImage(image);
insertcust(profile);
}
private void insertcust(Customerprofile profile) {
// TODO Auto-generated method stub
DatabaseHelper mydbhelper = new DatabaseHelper(Myimage.this);
SQLiteDatabase db = mydbhelper.getWritableDatabase();
ContentValues values = new ContentValues();
values.put(DatabaseHelper.KEY_NAME, profile.getName());
values.put(DatabaseHelper.KEY_ADDRESS, profile.getAddress());
values.put(DatabaseHelper.KEY_PINCODE, profile.getPincode());
values.put(DatabaseHelper.KEY_CITY, profile.getCity());
values.put(DatabaseHelper.KEY_IMAGE, profile.getImage());
long adcid = db.insert(DatabaseHelper.DATABASE_TABLE, null,
values);
db.close();
}
});
}
誰能幫我給我的解決方案存儲在數據庫中我ImageView
圖像。
