Get numbers from EditText
android, android-edittext, int, java, string
Solution
The exception is:
Java.lang.NumberFormatException: unable to parse '' as integer
And it's only because there is no value in the editbox1 field.
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.popupvalores);
valor1 = (EditText) findViewById (R.id.editText1);
myEditValue = valor1.getText().toString();
Log.debug("logtag", myEditValue); // Here you can see the output.
try {
valor = Integer.parseInt(myEditValue);
}
catch(Exception e) {
Log.e("logtag", "Exception: " + e.toString());
}
}
Problem
I know that his have been asked a few times, but I have been trying everything I have found with no luck. I'm still having a error. Here's my code. xml ``` <?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_gravity="center" android:background="@android:color/transparent" android:gravity="center" android:orientation="vertical" > <TextView android:id="@+id/textView1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="Write item value." android:textColor="@android:color/black" android:textSize="25dp" /> <EditText android:id="@+id/editText1" android:layout_width="80dp" android:layout_height="wrap_content" android:layout_marginBottom="202dp" android:ems="10" android:hint="Value" android:inputType="number" > <requestFocus /> </EditText> ``` java ``` public class PopupValores extends Activity { EditText valor1; String myEditValue; public static int valor; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.popupvalores); valor1 = (EditText) findViewById (R.id.editText1); myEditValue = valor1.getText().toString(); valor = Integer.parseInt(myEditValue); <<<<Line 20 } } ``` LogCat ``` 05-08 21:02:10.023: W/dalvikvm(6074): threadid=1: thread exiting with uncaught exception (group=0x40020578) 05-08 21:02:10.039: E/AndroidRuntime(6074): FATAL EXCEPTION: main 05-08 21:02:10.039: E/AndroidRuntime(6074): java.lang.RuntimeException: Unable to start activity ComponentInfo{com.dc.maker/com.dc.maker.PopupValores}: java.lang.NumberFormatException: unable to parse '' as integer 05-08 21:02:10.039: E/AndroidRuntime(6074): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1651) 05-08 21:02:10.039: E/AndroidRuntime(6074): at android.app.ActivityThread.handleLaunchActivity(ActivityThread.java:1667) 05-08 21:02:10.039: E/AndroidRuntime(6074): at android.app.ActivityThread.access$1500(ActivityThread.java:117) 05-08 21:02:10.039: E/AndroidRuntime(6074): at android.app.ActivityThread$H.handleMessage(ActivityThread.java:935) 05-08 21:02:10.039: E/AndroidRuntime(6074): at android.os.Handler.dispatchMessage(Handler.java:99) 05-08 21:02:10.039: E/AndroidRuntime(6074): at android.os.Looper.loop(Looper.java:130) 05-08 21:02:10.039: E/AndroidRuntime(6074): at android.app.ActivityThread.main(ActivityThread.java:3687) 05-08 21:02:10.039: E/AndroidRuntime(6074): at java.lang.reflect.Method.invokeNative(Native Method) 05-08 21:02:10.039: E/AndroidRuntime(6074): at java.lang.reflect.Method.invoke(Method.java:507) 05-08 21:02:10.039: E/AndroidRuntime(6074): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:867) 05-08 21:02:10.039: E/AndroidRuntime(6074): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:625) 05-08 21:02:10.039: E/AndroidRuntime(6074): at dalvik.system.NativeStart.main(Native Method) 05-08 21:02:10.039: E/AndroidRuntime(6074): Caused by: java.lang.NumberFormatException: unable to parse '' as integer 05-08 21:02:10.039: E/AndroidRuntime(6074): at java.lang.Integer.parseInt(Integer.java:362) 05-08 21:02:10.039: E/AndroidRuntime(6074): at java.lang.Integer.parseInt(Integer.java:332) 05-08 21:02:10.039: E/AndroidRuntime(6074): at com.popupclass.PopupValores.onCreate(PopupValores.java:20) 05-08 21:02:10.039: E/AndroidRuntime(6074): at android.app.Instrumentation.callActivityOnCreate(Instrumentation.java:1047) 05-08 21:02:10.039: E/AndroidRuntime(6074): at android.app.ActivityThread.performLaunchActivity(ActivityThread.java:1615) 05-08 21:02:10.039: E/AndroidRuntime(6074): ... 11 more ``` I'm trying to get a int from the EditText and then use it in other class to determinate a value of something. Can someone tell me what I'm doing wrong? Thanks
