    <p>I've stucked with the following problem: I need to validate, that EditText's value is an Integer between 1 and 1000. If it's not - I should put some of the default value into the EditText. When I try to do such a thing with following code - I get to the infinite loop (well, that was predictable). I've checked the similar questions, but I still can't figure out, how to make the code working.<BR>Are there any other ways to implement the desirable behaviour? How I should edit my code to achieve this?<BR></p> <pre><code> Long mailIntervalValue; EditText etMailInterval; . . . . etMailInterval=(EditText)findViewById(R.id.et_mail_check_interval); etMailInterval.setText(mailIntervalValue.toString()); etMailInterval.addTextChangedListener(new TextWatcher(){ public void afterTextChanged(Editable s) { Integer t=Integer.getInteger(s.toString()); if (t==null){ s.clear(); s.append(mailIntervalValue.toString()); mailIntervalValue=MessageManager.DEFAULT_TIME; } else mailIntervalValue=t.longValue(); if (mailIntervalValue&lt;1 || mailIntervalValue&gt;1000){ if (mailIntervalValue&lt;1) mailIntervalValue=1L; else mailIntervalValue=1000L; s.clear(); s.append(mailIntervalValue.toString()); Toast.makeText(MainActivity.this, MainActivity.this.getString(R.string.settings_timer_fail), Toast.LENGTH_SHORT).show(); } saveMailerPrefs(); } public void beforeTextChanged(CharSequence s, int start, int count, int after){} public void onTextChanged(CharSequence s, int start, int before, int count){} }); </code></pre>

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.
