Given below is the complete code to our app.Source: you come across custom Toasts that are different from your default Toast and you are wondering how they were made? Well, i am going to show you how, at least to an extent ) We can go through the same steps to convert the weight from pounds to kilograms. With this, we have completed our onClick function. We can display anything inside “, “and can even concatenate it with our doubleVariable.ĭuration: This parameter lets us describe the duration for which the toast will be displayed. Text: In this parameter, you should enter the data to be displayed in the toast. If you are in the inner class, you can use the function getApplicationContext().

Alternatively, we can also update our original doubleVariable because we don’t need to use it ahead in our app. So we just multiply our variable with 2.20462 and store the new value in another variable. 1 kg is approximately equal to 2.20462 lbs. Quite similar to how we use arithmetic operators in C, we can perform arithmetic operations on our variable using our standard syntax ( +, -, *, /, %). We don’t need to define the string variable because we can get similar results from the following code too:ĭouble doubleVariable = Double.parseDouble( editTextVariable.getText().toString()) īoth the methods are correct so any one can be used. It’s also in the data type that we need, i.e., Double. We have the value from the input field stored in our Double variable. The syntax for this looks like this:ĭouble doubleVariable = Double.parseDouble( stringVariable) Just like with the conversion to a string, we first define a variable of a double datatype. Convert String data type into Double data type: But since we are dealing with numbers, we have to use the Double data type to hold this value. Now, stringVariable holds the data in String form. String stringVariable = editTextVariable.getText().toString() We do this by using two functions, getText() and toString(). This variable will hold the value from editTextVariable in the form of a string. Convert this data into a String data type:

Now the variable editTextVariable will have the value entered by the user in the text field with the id textFieldName. EditText editTextVariable = (EditText) findViewById (R.id.
