    <p>I have an AlertDialog that is displayed, and want the text to have a countdown. While trying to implement it in the following way, the dialog displays exactly as needed, but I am trying to figure out how to make one of the TextViews change to the timer while the dialog is displayed. When I try to implement it in this way, it crashes, as you can see in the log info.</p> <pre><code>public void startOverlay() { AlertDialog.Builder builder = new AlertDialog.Builder(this); builder.setCancelable(false); // Get the layout inflater LayoutInflater inflater = getLayoutInflater(); View boxLayout = inflater.inflate(R.layout.overlay, null); builder.setView(boxLayout); Typeface flatui = Typeface.createFromAsset(getAssets(), "fonts/Flat-UI-Font.ttf"); TextView t1 = (TextView)boxLayout.findViewById(R.id.dialogtext1); final TextView t2 = (TextView)boxLayout.findViewById(R.id.dialogtext2); t1.setTypeface(flatui); t2.setTypeface(flatui); final AlertDialog receivedBox = builder.create(); receivedBox.show(); CountDownTimer timer = new CountDownTimer(6000, 1000) { public void onTick(long millisUntilFinished) { final int seconds = (int) (millisUntilFinished / 1000); log("Tick: " + seconds); if (seconds == 0) receivedBox.dismiss(); Handler mHandler = new Handler(); mHandler.post(new Runnable() { @Override public void run() { // executed on the UI thread t2.setText(seconds); } }); } public void onFinish() { receivedBox.dismiss(); log("done!"); beginFirst(); } }.start(); } </code></pre> <p>Log info:</p> <pre><code>06-24 12:01:18.977: E/AndroidRuntime(11682): FATAL EXCEPTION: main 06-24 12:01:18.977: E/AndroidRuntime(11682): android.content.res.Resources$NotFoundException: String resource ID #0x5 06-24 12:01:18.977: E/AndroidRuntime(11682): at android.content.res.Resources.getText(Resources.java:242) 06-24 12:01:18.977: E/AndroidRuntime(11682): at android.widget.TextView.setText(TextView.java:3773) 06-24 12:01:18.977: E/AndroidRuntime(11682): at com.workout.MainActivity$1$1.run(MainActivity.java:163) 06-24 12:01:18.977: E/AndroidRuntime(11682): at android.os.Handler.handleCallback(Handler.java:615) 06-24 12:01:18.977: E/AndroidRuntime(11682): at android.os.Handler.dispatchMessage(Handler.java:92) 06-24 12:01:18.977: E/AndroidRuntime(11682): at android.os.Looper.loop(Looper.java:137) 06-24 12:01:18.977: E/AndroidRuntime(11682): at android.app.ActivityThread.main(ActivityThread.java:4918) 06-24 12:01:18.977: E/AndroidRuntime(11682): at java.lang.reflect.Method.invokeNative(Native Method) 06-24 12:01:18.977: E/AndroidRuntime(11682): at java.lang.reflect.Method.invoke(Method.java:511) 06-24 12:01:18.977: E/AndroidRuntime(11682): at com.android.internal.os.ZygoteInit$MethodAndArgsCaller.run(ZygoteInit.java:1004) 06-24 12:01:18.977: E/AndroidRuntime(11682): at com.android.internal.os.ZygoteInit.main(ZygoteInit.java:771) 06-24 12:01:18.977: E/AndroidRuntime(11682): at dalvik.system.NativeStart.main(Native Method) </code></pre>

    1. COWhat exactly do you mean by "as I cannot change the text"? Compile error? App crash? App hang? Development OS crash?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
