<p>I'm creating a simple android app, which has and editText field and a textView field, the values within these fields are only numeric. </p> <p>I have created a button which on selecting, I would like the value of the edit text and text view to be added together, I would then like the editText to change to a value of '0' and teh total to be displayed in the textView.</p> <p>For example if the editText has a value of 10 and the textView has a value of 20 on pressing the button the total of 30 is displayed in the textView and the value of the editText displays 0.</p> <p>Here is my code so far, when I press the button at the moment the app crashes so I am not confident that I have coded correctly. I am new to java. Any help would be greatly appreciated.</p> <pre><code>public class durood extends Activity{ TextView txtCount; TextView totalCount; EditText enteramount; Button btnCount; Button addtotal1; Button addtotal2; Button cleartotal; static int count=0; double x=0; double y=0; double z=0; @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); // The activity is being created. setContentView(R.layout.durood); enteramount = (EditText)findViewById(R.id.enteramount); totalCount = (TextView)findViewById(R.id.totalCount); addtotal1=(Button)findViewById(R.id.addtototal1); addtotal2=(Button)findViewById(R.id.addtototal2); //add to total 1 addtotal1.setOnClickListener(new View.OnClickListener() { public void onClick(View v) { x=Double.parseDouble(enteramount.getText().toString()); y=Double.parseDouble(totalCount.getText().toString()); z=x+y; totalCount.setText(Double.toString(z)); } }); </code></pre> <p>LogCat</p>

Guidance

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.
