    <p>Sorry for seem making so clumpsy for the below code. To sum up, I am making a quiz game where user can choose 4 kinds of difficulties of the Question. if user choose checkbox 1 and 3, for example, the below code is intended to store string arrays from the string.xml into String[] NUM_ALL_QuestionNames. </p> <pre><code>//same for checkbox1,2,3, so here not duplicate // if (checkbox4=="yes") { NUM_EXP_QuestionNames = getResources().getStringArray(R.array.Num_Q_Expert_List); NUM_EXP_AnswerNames = getResources().getStringArray(R.array.Num_A_Expert_List); QuestionImport= 0; QuestionImport = NUM_EXP_QuestionNames.length; int i =0; while (i&lt;QuestionImport) { String Q_toimport = NUM_EXP_QuestionNames[i]; String A_toimport = NUM_EXP_AnswerNames[i]; NUM_ALL_QuestionNames.add(Q_toimport); NUM_ALL_AnswerNames.add(A_toimport); ++i; } }; NUM_ALLL_QuestionNames = new String[NUM_ALL_QuestionNames.size()]; //convert ArrayList&lt;String&gt; to String[] NUM_ALLL_AnswerNames = new String[NUM_ALL_AnswerNames.size()]; //convert ArrayList&lt;String&gt; to String[] </code></pre> <p>At last NUM_ALL_Questionnames would be converted back from ArrayList NUM_ALLL_QuestionNames to String[] for further processing.</p> <p>The files in the string.xml should have no problem because when I try set as follows (directly extract from the string.xml) the apps runs fine:</p> <pre><code>NUM_ALLL_QuestionNames = getResources().getStringArray(R.array.Num_Q_Simple_List); NUM_ALLL_AnswerNames = getResources().getStringArray(R.array.Num_A_Simple_List); </code></pre> <h2>Question:</h2> <ol> <li><p>Now is it data from string.xml in String[] format, it was then added to the List, where this List at last convert back to String[]. Are there any modification such that is no need this conversion. It is better if string.xml can be directly to String[]</p></li> <li><p>When goes on executeing the app, logcat does not show any error. However, the Emulator keep black screen. Why does it happen? Are there any endless loop for the Code?</p></li> </ol> <p>Many thanks!</p>

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.
