POEditText to Int
text
Body
copied!<p>I'm new to Java and Android development so I decided to make a simple app that takes in two fields and puts them in a simple math equation. However I have to convert the EditText into Int before I can do any math with them, right? In the XML file I have set both EditTexts to android:inputType="number". My attempts have been like this:</p> <blockquote> <pre><code> final EditText height = (EditText) findViewById (R.id.height); String heightString = height.getText().toString(); final int heightInt = Integer.parseInt(heightString); </code></pre> </blockquote> <p>and</p> <blockquote> <pre><code> final EditText height = (EditText) findViewById (R.id.height); final int heightInt = Integer.parseInt(height.getText().toString()); </code></pre> </blockquote> <p>I also tried Integer.valueOf in both cases but it always force closes my app when I run it and if I comment out that int heightInt it doesn't force close.</p> <p>Here's the whole code:</p> <blockquote> <p>package com.body.calculator;</p> <pre><code>import android.app.Activity; import android.content.Context; import android.os.Bundle; import android.os.Vibrator; import android.view.View; import android.widget.Button; import android.widget.EditText; import android.widget.TextView; public class bmi extends Activity { /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); final TextView results = (TextView) findViewById(R.id.results); final EditText height = (EditText) findViewById (R.id.height); String heightString = height.getText().toString(); final int heightInt = Integer.parseInt(heightString); final EditText weight = (EditText) findViewById (R.id.weight); final Vibrator vib = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); Button submit_bmi = (Button) findViewById(R.id.submit_bmi); submit_bmi.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { if (height.getText().toString().equals("") && weight.getText().toString().equals("")) { results.setText("Both fields are empty"); vib.vibrate(100); } else if (height.getText().toString().equals("")) { results.setText("Height is empty"); vib.vibrate(100); } else if (weight.getText().toString().equals("")) { results.setText("Weight is empty"); vib.vibrate(100); } else { results.setText(""); } } }); } } </code></pre> </blockquote> <p>Any help would be appreciated. Thanks, Arnar.</p>
