How do I convert from binary to decimal in java (using android studio)

Question

I am making an android app and one of the components of the app is designed to take a number in binary and convert it to decimal. Every time I run it, it crashes. ``` public void Button0Clicked(View v) { TextView myText = (TextView)findViewById(R.id.textView); if (firstType == true) { myText.setText(""); firstType = false; } myText.setText(myText.getText() + "0"); } public void Button1Clicked(View v) { TextView myText = (TextView)findViewById(R.id.textView); if (firstType == true) { myText.setText(""); firstType = false; } myText.setText(myText.getText() + "1"); } public void Conversion(View view) { TextView myText = (TextView)findViewById(R.id.textView); int decimalValue = Integer.parseInt(myText.getText().toString(),2); TextView result = (TextView)findViewById(R.id.textView2); result.setText(decimalValue); } ``` I've narrowed the problem down to some problem with the Integer.parseint() function, is my implementation wrong?

Accepted Answer

Change

```
 result.setText(decimalValue); // int param
```

To:

```
 result.setText(Integer.toString(decimalValue)); // string param
```

And it will work just fine.

Function View.setText() is overloaded for String and integer type of parameter.

When the compiler detected an integer param, as is your case, it attempts to find a String resource by that ID.

Remember - never pass an integer value to setText() unless it is a resource ID.
