如何在Android应用程序的每个标签中添加唯一内容

Question

I'm trying to make an app that has three tabs, each with different but linked content. Currently, I want some features to appear on one tab but not on another. For example, I would like a SeekBar to be displayed on only one of the tabs. But, currently, it is displayed for all of them.

I greatly appreciate any help

It seems like you want to dynamically add content to the TabHost . You will be able to add different tabs to the TabActivity once it is created based on a variable. Here is an example ...

TabHost host = findViewById(R.id.my_tabhost);
boolean boo = true; //Variable that will decide what tabs to add
host.setup(); //Need to call before adding tabs
if (boo)
    host.addTab(host.newTabSpec("Hello").setIndicator("Hello").setContent(new Intent(this, HelloActivity.class)));
else
    host.addTab(host.newTabSpec("Goodbye").setIndicator("Goodbye").setContent(new Intent(this, GoodbyeActivity.class));

This way the tabs will be different if boo is true or if boo is false. Then you can add your content to HelloActivity and GoodbyeActivity .
