Through the study of layout, it is the first time to write the design of the entire interface, mainly to exercise my basic layout nesting ability, and record it for future work and study!
Design Interface Diagram
Design ideas
1. Exercise your basic layout ability, the entire page layout adopts LinearLayout nested layer by layer.
2. In addition to the TextView text box control, two Switch controls are used.
3. Realize hyperlinks to some text in the text box by customizing the getClickSpan method.
4. The two Button buttons use AlertDialog to prompt, and the completion uses toast to prompt.

}question:
1. Wrote that AlertDialog does not run and does not pop up during debugging.
Solution: Remember not to forget to call dialog.show();
2. The title bar is hidden in the main activity, and the same ActionBar.hide(); method cannot be hidden in other activities.
Solution: Remember to introduce the following in the registration Xml file:
android:theme="@style/Theme.AppCompat.Light.NoActionBar"3. Select part of the text in the TextView to hyperlink to the desired active page.
Solution: Use the custom method getClickableSpan to select the part of the required hyperlink through spanableString.setSpan.
private SpannableString getClickableSpan1(){
SpannableString spannableString = new SpannableString(tv_privacy1.getText().toString());
ClickableSpan clickableSpan = new ClickableSpan() {
@Override
public void onClick(@NonNull View widget) {
Intent intent1 = new Intent(MainActivity.this,UserPrivacymsg.class);
startActivity(intent1);
}
@Override
public void updateDrawState(@NonNull TextPaint ds) {
super.updateDrawState(ds);
ds.setUnderlineText(false);
}
};
spannableString.setSpan(clickableSpan,48,58, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
return spannableString;
} tv_privacy1.setText(getClickableSpan1());
tv_privacy1.setMovementMethod(LinkMovementMethod.getInstance());Basically finished writing the simple product introduction setting page, there is still a lot of room for improvement.
Thanks!
mutual encouragement!
