I'm trying to create a Android app but I'm getting an error when clicking a button.
What I'm trying to do is convert a String to a double. I can't use the text field as a number, because I'm working with latitude and longitude, so I need negative numbers, and type="number" doesn't allow that.
This is the function that I execute:
public void insertSite(View view) {
String type = ((AutoCompleteTextView)findViewById(R.id.type)).getText().toString();
String address = ((AutoCompleteTextView)findViewById(R.id.address)).getText().toString();
String city = ((AutoCompleteTextView)findViewById(R.id.city)).getText().toString();
String district = ((AutoCompleteTextView)findViewById(R.id.district)).getText().toString();
String cep = ((AutoCompleteTextView)findViewById(R.id.cep)).getText().toString();
String state = ((AutoCompleteTextView)findViewById(R.id.state)).getText().toString();
double latitude = Double.parseDouble(((EditText)findViewById(R.id.latitude)).getText().toString());
double longitude = Double.parseDouble(((AutoCompleteTextView)findViewById(R.id.longitude)).getText().toString());
double altitude = Double.parseDouble(((AutoCompleteTextView)findViewById(R.id.altitude)).getText().toString());
try {
VivoDbDAO dao = new VivoDbDAO(this);
dao.insertSite(
type,
address,
city,
district,
state,
cep,
latitude,
longitude,
altitude);
Toast.makeText(this, "Site 1 inserido", Toast.LENGTH_SHORT).show();
Intent intent = new Intent(this, CadastroImovel2Activity.class);
startActivity(intent);
finish();
} catch (Exception e) {
Toast.makeText(this, e.toString(), Toast.LENGTH_LONG).show();
}
}
And here is the layout:

The Log says that you have entered an invalid double.May be the problem is with
double latitude = Double.parseDouble(((EditText)findViewById(R.id.latitude)).getText().toString());
double longitude = Double.parseDouble(((AutoCompleteTextView)findViewById(R.id.longitude)).getText().toString());
double altitude = Double.parseDouble(((AutoCompleteTextView)findViewById(R.id.altitude)).getText().toString());
ie. The value in latitude,longitude, altitude may contains invalid double values.May be if there is no value in that field can cause this error.Use this.
if(((EditText)findViewById(R.id.latitude)).getText().toString().length()!=0&&((EditText)findViewById(R.id.longitude))).getText().toString().length()!=0&&((EditText)findViewById(R.id.altitude)).getText().toString().length()!=0){
double latitude = Double.parseDouble(((EditText)findViewById(R.id.latitude)).getText().toString());
double longitude = Double.parseDouble(((AutoCompleteTextView)findViewById(R.id.longitude)).getText().toString());
double altitude = Double.parseDouble(((AutoCompleteTextView)findViewById(R.id.altitude)).getText().toString());}
It seems that you are trying to create a double out of an empty string. How about check field contents for empty values before parsing it as a double?

At least one of the drawables referenced in your second XML file is too big.
Check the following drawables and resize them:
sheep
title
list_fluid
PNGs generally don't need to be very large. Keep them below 1600x1600 if you can, preferably 800x800.
I'm making a pretty basic 6-7 activity app, trying to keep it really simple. I've succesfully added 4 other instances where at the bottom of the app you press "NEXT" and it takes you to the next activity in the app. However, I'm stuck and can't figure out how to continue. I've tried debugging and can't figure out what the error message means. THanks for your help.

You should have a TextView with id 'totalMonthlyIncome' in your XML layout. (According to the Java code) Just make sure that's there and it will solve the issue.
"Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'java.lang.CharSequence android.widget.TextView.getText()' on a null object reference
at com.example.android.budgeit10.expenses.fourthNext(expenses.java:86)"
According to the logcat error is in expenses.java - line 86
I have a NullpointerException but i can't figure out why! please your help as i'm struggling with it :
Here's my XML resource :
<?xml version="1.0" encoding="utf-8"?>

android:layout_width="wrap_content"
android:layout_height="wrap_content"

</RelativeLayout>
Below my Java instructions :
The setContentView is before the use of the actual TextView
final Dialog dialog = new Dialog(searchActivity.this);
dialog.setContentView(R.layout.custom_dialog);``
ImageView closeBtn =(ImageView)findViewById(R.id.imageViewClose);
closeBtn.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
finish();
}
});
