I want to display an AlertDialog, when the dialog should be appear I get the next message:
IllegalStateException: You need to use a Theme.AppCompat theme (or descendant) with this activity.
This is the code i'm using to display the dialog:
new AlertDialog.Builder(getBaseContext())
.setTitle("Not set yet :(")
.setMessage("You haven't set the directories to search in... Do you want to set it now?")
.setPositiveButton(android.R.string.yes, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Intent i = new Intent(MainActivity.this, SettingsActivity.class);
startActivity(i);
}
})
.setNegativeButton(android.R.string.no, new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
}
})
.show();
This is the MainActivity headline:
public class MainActivity extends AppCompatActivity
This is my styles.xml
<!-- Base application theme. -->
<style name="AppTheme" parent="Theme.AppCompat.Light.DarkActionBar">
<!-- Customize your theme here. -->
<item name="colorPrimary">@color/colorPrimary</item>
<item name="colorPrimaryDark">@color/colorPrimaryDark</item>
<item name="colorAccent">@color/colorAccent</item>
</style>
<style name="AppTheme.NoActionBar">
<item name="windowActionBar">false</item>
<item name="windowNoTitle">true</item>
</style>
<style name="AppTheme.AppBarOverlay" parent="ThemeOverlay.AppCompat.Dark.ActionBar" />
<style name="AppTheme.PopupOverlay" parent="ThemeOverlay.AppCompat.Light" />
</resources>
I've tried to looking for answers over the internet and couldn't find an answer, how do I fix this problem? I need an ActionBar, do I need to change the inheritance? Or should I change something in the AndroidManifest.xml or in styles.xml?
Thanks!
Add this in your style.xml
<style name="AlertDialogCustom" parent="Theme.AppCompat.Light.Dialog.Alert">
<item name="colorAccent">@color/colorAccent</item>
<item name="android:textColorPrimary">@color/colorPrimary</item>
<item name="android:background">#FFFFFF</item>
</style>
And use this for show Dialog (exit dialog example) in your MainActivity.java :
AlertDialog.Builder builder = new AlertDialog.Builder(YourMainActivity.this, R.style.AlertDialogCustom);
builder.setTitle(getResources().getString(R.string.title));
builder.setMessage(getResources().getString(R.string.exit_dialog));
builder.setPositiveButton(getResources().getString(R.string.ok_dialog), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int id) {
YourMainActivity.this.finish();
}
});
builder.setNegativeButton(getResources().getString(R.string.cancel_dialog), null);
builder.show();
Than in string.xml :
<string name="cancel_dialog">CANCEL</string>
<string name="ok_dialog">OK</string>
<string name="exit_dialog">Are you sure you want to quit?</string>
<string name="title">Your App Title</string>
In colors.xml (optional):
<item name="colorAccent" type="color">#FFFF8800</item>
<item name="colorPrimary" type="color">#FFCC0000</item>
