    <p>So,i want to make this app that puts the EditTexts that i create dynamically in a list and then reads from that list but i'm kind of stuck,my app crashes.Could you please tell me what i'm doing wrong ?I've tested different things,tried to change some stuff but i didn't find the problem. I tried to see if it can show cant[1] but it crashes even when trying that. Here's my code : </p> <pre><code> List&lt;EditText&gt; allpret = new ArrayList&lt;EditText&gt;(); List&lt;EditText&gt; allcant = new ArrayList&lt;EditText&gt;(); public void produsnou(View v) { LinearLayout l1 = (LinearLayout) findViewById(R.id.layout1); EditText et = new EditText(this); et.setHint("Produs"); l1.addView(et); LinearLayout l2 = (LinearLayout) findViewById(R.id.layout2); EditText et2 = new EditText(this); et2.setHint("Cantitate"); et2.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL); allcant.add(et2); l2.addView(et2); LinearLayout l3 = (LinearLayout) findViewById(R.id.layout3); EditText et3 = new EditText(this); et3.setHint("Pret"); et3.setInputType(InputType.TYPE_CLASS_NUMBER | InputType.TYPE_NUMBER_FLAG_DECIMAL); l3.addView(et3); allpret.add(et3); } public void calculeaza(View v) { String[] cant = new String[allcant.size()]; for (int j = 0; j &lt; allcant.size(); j++) { cant[j] = allcant.get(j).getText().toString(); String[] pret = new String[allcant.size()]; for (int k = 0; j &lt; allpret.size(); k++) { pret[k] = allpret.get(k).getText().toString(); } TextView totalf = (TextView) findViewById(R.id.total); totalf.setText("Total: " +cant[0]); } } </code></pre> <p>And here's logcat:</p> <pre><code>06-08 23:58:07.655: E/AndroidRuntime(7728): FATAL EXCEPTION: main 06-08 23:58:07.655: E/AndroidRuntime(7728): java.lang.IllegalStateException: Could not execute method of the activity 06-08 23:58:07.655: E/AndroidRuntime(7728): at android.view.View$1.onClick(View.java:3704) 06-08 23:58:07.655: E/AndroidRuntime(7728): at android.view.View.performClick(View.java:4232) 06-08 23:58:07.655: E/AndroidRuntime(7728): at android.view.View$PerformClick.run(View.java:17318) 06-08 23:58:07.655: E/AndroidRuntime(7728): at android.os.Handler.handleCallback(Handler.java:615) 06-08 23:58:07.655: E/AndroidRuntime(7728): at android.os.Handler.dispatchMessage(Handler.java:92) 06-08 23:58:07.655: E/AndroidRuntime(7728): at android.os.Looper.loop(Looper.java:137) 06-08 23:58:07.655: E/AndroidRuntime(7728): at android.app.ActivityThread.main(ActivityThread.java:4921) 06-08 23:58:07.655: E/AndroidRuntime(7728): at java.lang.reflect.Method.invokeNative(Native Method) 06-08 23:58:07.655: E/AndroidRuntime(7728): at java.lang.reflect.Method.invoke(Method.java:511) 06-08 23:58:07.655: E/AndroidRuntime(7728): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1038) 06-08 23:58:07.655: E/AndroidRuntime(7728): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:805) 06-08 23:58:07.655: E/AndroidRuntime(7728): at dalvik.system.NativeStart.main(Native Method) 06-08 23:58:07.655: E/AndroidRuntime(7728): Caused by: java.lang.reflect.InvocationTargetException 06-08 23:58:07.655: E/AndroidRuntime(7728): at java.lang.reflect.Method.invokeNative(Native Method) 06-08 23:58:07.655: E/AndroidRuntime(7728): at java.lang.reflect.Method.invoke(Method.java:511) 06-08 23:58:07.655: E/AndroidRuntime(7728): at android.view.View$1.onClick(View.java:3699) 06-08 23:58:07.655: E/AndroidRuntime(7728): ... 11 more 06-08 23:58:07.655: E/AndroidRuntime(7728): Caused by: java.lang.IndexOutOfBoundsException: Invalid index 3, size is 3 06-08 23:58:07.655: E/AndroidRuntime(7728): at java.util.ArrayList.throwIndexOutOfBoundsException(ArrayList.java:251) 06-08 23:58:07.655: E/AndroidRuntime(7728): at java.util.ArrayList.get(ArrayList.java:304) 06-08 23:58:07.655: E/AndroidRuntime(7728): at com.example.testlayout.MainActivity.calculeaza(MainActivity.java:66) 06-08 23:58:07.655: E/AndroidRuntime(7728): ... 14 more 06-08 23:58:07.680: D/dalvikvm(7728): GC_CONCURRENT freed 237K, 11% free 7249K/8135K, paused 2ms+3ms, total 38ms 06-08 23:58:17.125: I/Process(7728): Sending signal.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.

SQuiL has stopped working due to an internal error.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
