    text
    copied!<p>in my android application I have a Button which adds a new dynamic Spinner to the Layout. All of the created Spinners are using the same Array.</p> <p>What is working until now, I can save the number of created Spinners and recreate them after restarting the Application. But I really would like to save the selectedPosition of each Spinner in the sharedPreferences and this is where I'm stucking in a ForceClose Desaster...</p> <p>In my understanding, every Spinner gets an ID when created so you can save the Position bounded on this ID in the preferences.</p> <p>So this is what I did:</p> <pre><code>public void addSpinner(){ LinearLayout AddLayout = (LinearLayout)findViewById(R.id.linearAddScroll); spinner = new Spinner(this); ArrayAdapter&lt;?&gt; adapt = ArrayAdapter.createFromResource(this, R.array.Filter, android.R.layout.simple_spinner_item); adapt.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item); spinner.setAdapter(adapt); AddLayout.addView(spinner); } </code></pre> <p>this creates the Spinner.</p> <pre><code>public void onClick(View v) { addSpinner(); int ID = 1000+x; spinner.setId(ID); Toast.makeText(MatReporterActivity.this,"ID" + ID, 5) .show(); x++; } </code></pre> <p>set the ID.</p> <p>This is what I do in the on Create method:</p> <pre><code>x = settings.getInt("xsave", 1); for(y = 1; y &lt; x; y++){ addSpinner(); int ID = 1000+y; Spinner s = (Spinner) findViewById(ID); String ys= Integer.toString(ID); Toast.makeText(MatReporterActivity.this,"ID" +ys, 5) .show(); int yf = settings.getInt(ys, 1); s.setSelection(yf); } </code></pre> <p>And this onStop():</p> <pre><code>SharedPreferences settings = PreferenceManager .getDefaultSharedPreferences(this); SharedPreferences.Editor editor = settings.edit(); editor.putInt("xsave", x); for(y = 1; y &lt; x; y++){ int ID = 1000+y; Spinner s2= (Spinner) findViewById(ID); int possS = s2.getSelectedItemPosition(); Toast.makeText(MatReporterActivity.this, "IDStop" + ID, 5) .show(); String ys= Integer.toString(ID); editor.putInt(ys, possS); } editor.commit(); } </code></pre> <p>I think there is a logical Problem in the onCreate Method, but I'm not able to find it, also I didn't find any help in the web how to populate and save dynamically created spinners.</p> <p>So maybe someone has an idea. thanks.</p>
