Simple customizable dialog to pick a theme (background and text colors). Supports small screens. May be useful for custom text readers.
Portrait:
Small screens:
ThemePickerDialogFragment themePickerDialog = ThemePickerDialogFragment.newInstance(
new ThemePickerDialog.Builder(MainActivity.this)
.initBackgroundColor(color)
.initTextColor(color)
.dialogBackgroundColor(color)
.dialogDefaultThemesBackgroundColor(color)
.tabTextColor(color)
.tabIndicatorColor(color)
.tabDividerColor(color)
.buttonsTextColor(color)
.themeTextColor(color)
.onPositive(onPositiveCallback)
.onNegative(onNegativeCallback)
);
themePickerDialog.show(getFragmentManager(), TAG);
// ...
ThemePickerDialog.OnPositiveCallback onPositiveCallback = new ThemePickerDialog.OnPositiveCallback() {
@Override
public void onClick(@ColorInt int backgroundColor, @ColorInt int textColor) {
// do stuff
}
};
You can also use xxxColorRes(int colorRes) methods instead of all methods described above to provide color resource instead of int color variable.
For example:
.initBackgroundColorRes(colorRes)

Colors explanations.
The dialog is able to save state and change its layout either activity is recreating or not (android:configChanges="..." in AndroidManifest.xml) on configuration changes.
You have to take care only about callbacks when activity is recreating. There are two ways to do it.
- If your activity is implementing dialog's callbacks, you don't have to carry about anything. During dialog recreation it will try to cast attached activity to a listener.
public class MainActivity extends AppCompatActivity implements ThemePickerDialog.OnPositiveCallback {
- If you are setting callbacks like this:
ThemePickerDialogFragment themePickerDialog = ThemePickerDialogFragment.newInstance(
new ThemePickerDialog.Builder(MainActivity.this)
// ...
.onPositive(onPositiveCallback)
.onNegative(onNegativeCallback)
);
Then you have to re-set them in onCreate method if dialog is showing:
@Override
protected void onCreate(Bundle savedInstanceState) {
// ...
if (savedInstanceState != null) {
ThemePickerDialogFragment themePickerDialogFragment = (ThemePickerDialogFragment) getFragmentManager()
.findFragmentByTag(TAG);
if (themePickerDialogFragment != null)
themePickerDialogFragment.onPositive(onPositiveCallback);
}
}
For details take a look at sample application.
- Make showing default themes optional and add a possibility to customize them.
