    <p>I am trying to display a textValue inserted by the user from the main class to another class/window. </p> <p>On my main class I made this method </p> <pre><code>public String retChoice() { choices[0] ="sasda"; //editText.getText().toString(); //pass from click button to method. choices[1] ="asdsa";//editText2.getText().toString(); choices[2] = "asdsads"; //editText3.getText().toString(); finalChoice =rand.nextInt(2); displayChoice = choices[finalChoice]; return displayChoice; } </code></pre> <p>which works </p> <p>but this </p> <pre><code>public String retChoice() { choices[0] = editText.getText().toString(); //pass from click button to method. choices[1] = editText2.getText().toString(); choices[2] = editText3.getText().toString(); finalChoice =rand.nextInt(2); displayChoice = choices[finalChoice]; return displayChoice; } </code></pre> <p>completely crashes the app. </p> <p>Here's my other class of which I'm going to display the choice. </p> <pre><code>public class resultScreen extends Activity { MainActivity ma = new MainActivity(); //Method supposedly retrieves the string data from MainActivity Class but somehow displayed null instead. //Find a way to keep the string variable when transfering from one class to another class. String finalResult = ma.retChoice(); public void onCreate(Bundle resultScreen){ super.onCreate(resultScreen); setContentView(R.layout.resultscreen); //ma.displayChoice.toString(); String str = finalResult; TextView text = (TextView) findViewById(R.id.textView1); text.setText(str); } </code></pre>

    1. COPlease do not repost just because you don't get the right answer. Try to make your original post better so people can help you. In your OP you were asked to provide logcat more than once. If you did that you would probably have an answer by now

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.
