它对我说，我没有名为照片的专栏，但我有：
public void onCreate(SQLiteDatabase db) {
db.execSQL("CREATE TABLE " + DbConstants.TABLE_NAME + " " +
"(" + _ID + " INTEGER PRIMARY KEY AUTOINCREMENT, " +
DbConstants.NAME + " TEXT NOT NULL," +
DbConstants.PHONE + " TEXT NOT NULL," +
DbConstants.PHOTO + "TEXT NOT NULL," +
DbConstants.EMAIL +"TEXT NOT NULL,"+");");
}
这是我的db常量.java：
public static final String NAME = "name";
public static final String PHONE = "phone";
public static final String EMAIL = "email";
public static final String PHOTO="photo";
当我尝试添加联系人时按下保存按钮时出现错误。
这是我的.java，我添加了方法：
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
showDatabaseContent();
lv1 = getListView();
lv1.setTextFilterEnabled(true);

cursor = (Cursor) a.getItemAtPosition(position);
itemId = cursor.getString(0);
openOptionsMenu();
}
});
lv1.setOnItemSelectedListener(new OnItemSelectedListener() {
public void onItemSelected(AdapterView<?> parent, View view, int position, long id){
}

// TODO Auto-generated method stub

这是我的.java，我已经实现了保存按钮的方法：
protected void onCreate(Bundle savedInstanceState){
super.onCreate(savedInstanceState);
setContentView(R.layout.contactdetails);
Button sButton = (Button) findViewById(R.id.button1);
sButton.setOnClickListener(new OnClickListener() {
public void onClick(View arg0) {
// in onCreate or any event where your want the user to
// select a file
Intent intent = new Intent();
intent.setType("image/*");
intent.setAction(Intent.ACTION_GET_CONTENT);
startActivityForResult(Intent.createChooser(intent,
"Select Picture"), SELECT_PICTURE);
}
});
Bundle incomingActionType = getIntent().getExtras();
operationType = incomingActionType.getString("mod_type");
if (operationType.equals("addPerson")){
nameField = (EditText) findViewById(R.id.contactName);
mobilePhoneField = (EditText) findViewById(R.id.contactmobile);
emailField = (EditText) findViewById(R.id.contactemail);
}
else if (operationType.equals("modifyPerson")){
String modifyFirstName = incomingActionType.getString("cFirstName");
nameField = (EditText) findViewById(R.id.contactName);
nameField.setText(modifyFirstName);
String modifyPhoneNumber = incomingActionType.getString("cMobilePhone");
mobilePhoneField = (EditText) findViewById(R.id.contactmobile);
mobilePhoneField.setText(modifyPhoneNumber);
String modifyEmail = incomingActionType.getString("cEmail");
emailField = (EditText) findViewById(R.id.contactemail);
emailField.setText(modifyEmail);
}
cancelButton = (Button) findViewById(R.id.cancelcontactbutton);
saveContactButton = (Button) findViewById(R.id.savecontactbutton);
saveContactButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent resultIntent = new Intent();
Bundle contactData = new Bundle();
if (nameField.getText().toString().length() == 0){
new AlertDialog.Builder(ContactDetails.this).setTitle("Error").setMessage("First name field cannot be empty!").setNeutralButton("Close", null).show();
} else if (mobilePhoneField.getText().toString().length() == 0){
new AlertDialog.Builder(ContactDetails.this).setTitle("Error").setMessage("Mobile Phone field cannot be empty!").setNeutralButton("Close", null).show();
} else if (emailField.getText().toString().length() == 0){
new AlertDialog.Builder(ContactDetails.this).setTitle("Error").setMessage("Email field cannot be empty!").setNeutralButton("Close", null).show();
} else{
contactData.putString("contactFirstName", nameField.getText().toString());
contactData.putString("contactMobilePhone", mobilePhoneField.getText().toString());
contactData.putString("contactEmail", emailField.getText().toString());
contactData.putString("poza",poza.getText().toString());
resultIntent.putExtra("contactData", contactData);
if (operationType.equals("addPerson")){
setResult(RESULT_FIRST_USER, resultIntent);
}else if (operationType.equals("modifyPerson")){
setResult(RESULT_MODIFY_USER, resultIntent);
}
finish();
}
}
});
cancelButton.setOnClickListener(new View.OnClickListener(){
public void onClick(View v) {
Intent resultIntent = new Intent();
setResult(RESULT_CANCELED, resultIntent);
finish();
}
});
}
public void onActivityResult(int requestCode, int resultCode, Intent data) {
if (resultCode == RESULT_OK) {
if (requestCode == 1) {
// currImageURI is the global variable I'm using to hold the content:// URI of the image
Uri currImageURI = data.getData();
getRealPathFromURI(currImageURI);
}
}
}
public String getRealPathFromURI(Uri currImageURI) {
// can post image
String [] proj={MediaStore.Images.Media.DATA};
Cursor cursor = managedQuery( currImageURI,
proj, // Which columns to return
null, // WHERE clause; which rows to return (all rows)
null, // WHERE clause selection arguments (none)
null); // Order-by clause (ascending by name)
int column_index = cursor.getColumnIndexOrThrow(MediaStore.Images.Media.DATA);
cursor.moveToFirst();
poza=(EditText)findViewById(R.id.editText1);
poza.setText(currImageURI.toString());
return cursor.getString(column_index);
}
}
我认为错误在这里：db.insertOrThrow(DbConstants.TABLE_NAME, null, vals);
但不知道原因。
答案 0 :(得分：3)

创建数据库时，您没有为照片列（以及后续电子邮件地址）指定数据类型。最有可能的是，这会导致错误，从而阻止色谱柱的产生。在这里指定一个数据类型，你应该很好。
答案 1 :(得分：0)
未定义用于创建数据库的脚本中的PHOTO和EMAIL类型。另外别忘了把逗号。
答案 2 :(得分：0)
修复上述错误。如果不能正常工作从连接的设备或模拟器卸载您的应用程序，然后运行您的应用程序。
