Answer 1

I'm very sleepy and tired right now but wouldn't this work?:

EditText et = (EditText)findViewById(R.id.editText1);
String sTextFromET = et.getText().toString();
int nIntFromET = new Integer(sTextFromET).intValue();

OR

try
{
    int nIntFromET = Integer.parseInt(sTextFromET);
}
catch (NumberFormatException e)
{
    // handle the exception
}

Answer 2

Use Integer.parseInt, and make sure you catch the NumberFormatException that it throws if the input is not an integer.

Answer 3

you have to used.

String value= et.getText().toString();
int finalValue=Integer.parseInt(value);

if you have only allow enter number then set EditText property.

android:inputType="number"

if this is helpful then accept otherwise put your comment.

Answer 4

You can use parseInt with try and catch block

try
{
    int myVal= Integer.parseInt(mTextView.getText().toString());
}
catch (NumberFormatException e)
{
    // handle the exception
    int myVal=0;
}

Or you can create your own tryParse method :

public Integer tryParse(Object obj) {
    Integer retVal;
    try {
        retVal = Integer.parseInt((String) obj);
    } catch (NumberFormatException nfe) {
        retVal = 0; // or null if that is your preference
    }
    return retVal;
}

and use it in your code like:

int myVal= tryParse(mTextView.getText().toString());

---

Note: The following code without try/catch will throw an exception

int myVal= new Integer(mTextView.getText().toString()).intValue();

Or

int myVal= Integer.decode(mTextView.getText().toString()).intValue();

Answer 5

In Kotlin, you can do this.

val editText1 = findViewById(R.id.editText)
val intNum = editText1.text.toString().toInt()

Answer 6

I had the same problem myself. I'm not sure if you got it to work though, but what I had to was:

EditText cypherInput;
cypherInput = (EditText)findViewById(R.id.input_cipherValue);
int cypher = Integer.parseInt(cypherInput.getText().toString());

The third line of code caused the app to crash without using the .getText() before the .toString().

Just for reference, here is my XML:

<EditText
    android:id="@+id/input_cipherValue"
    android:inputType="number"
    android:layout_width="match_parent"
    android:layout_height="wrap_content" />
