1.xml布局
?
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" android:id="@+id/ptas_operation_bottom_bar" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:gravity="center_vertical" android:orientation="horizontal" android:paddingLeft="0.6600001dip" android:paddingRight="0.6600001dip"> <RadioGroup android:id="@+id/main_radio" style="@style/Ptas_Tab_Radio_Group_Bg" android:layout_gravity="bottom"> <RadioButton android:id="@+id/radio_navigation" style="@style/Ptas_Tab_Bottom" android:layout_marginTop="2.0dip" android:text="文字一" /> <RadioButton android:id="@+id/radio_vary" style="@style/Ptas_Tab_Bottom" android:layout_marginTop="2.0dip" android:text="文字一" /> <RadioButton android:id="@+id/radio_doing" style="@style/Ptas_Tab_Bottom" android:layout_marginTop="2.0dip" android:text="文字一" /> <RelativeLayout android:id="@+id/notice_re" style="@style/Ptas_Tab_Bottom_Notice"> <RadioButton android:id="@+id/radio_notice" style="@style/Ptas_Tab_Bottom" android:layout_centerInParent="true" android:layout_marginTop="2.0dip" android:text="文字一" /> <TextView android:id="@+id/notice_count_text" android:layout_width="28dip" android:layout_height="28dip" android:layout_alignParentRight="true" android:layout_alignParentTop="true" android:background="@drawable/notice_count" android:gravity="center" android:text="0" android:textSize="13dip" android:textStyle="bold" /> </RelativeLayout> <RadioButton android:id="@+id/radio_setting" style="@style/Ptas_Tab_Bottom" android:layout_marginTop="2.0dip" android:text="文字一" /> </RadioGroup></LinearLayout>?

2.代码控制切换GroupRadio

?
private void mainBtnGroupOnclick() { mainBtnGroup.setOnCheckedChangeListener(new RadioGroup.OnCheckedChangeListener() { @Override public void onCheckedChanged(RadioGroup group, int checkedId) { if (navigaionBtn.getId() == checkedId) { tabHost.setCurrentTab(1); } else if (varyBtn.getId() == checkedId) { tabHost.setCurrentTab(2); } else if (doingBtn.getId() == checkedId) { tabHost.setCurrentTab(3); } else if (settingBtn.getId() == checkedId) { tabHost.setCurrentTab(5); } if (checkedId != noticeBtn.getId()) { noticeBtn.setChecked(false); noticeBtn.setFocusableInTouchMode(false); } } }); navigaionBtn.setOnClickListener(this); varyBtn.setOnClickListener(this); doingBtn.setOnClickListener(this); noticeBtn.setOnClickListener(this); settingBtn.setOnClickListener(this); } @Override public void onClick(View view) { if (view.getId() == noticeBtn.getId()) { noticeBtn.setBackgroundResource(R.drawable.home_btn_bg_d); navigaionBtn.setChecked(false); doingBtn.setChecked(false); varyBtn.setChecked(false); settingBtn.setChecked(false); settingBtn.setFocusableInTouchMode(false); varyBtn.setFocusableInTouchMode(false); doingBtn.setFocusableInTouchMode(false); navigaionBtn.setFocusableInTouchMode(false); tabHost.setCurrentTab(4); } else { noticeBtn.setBackgroundColor(android.R.color.transparent); } }?3.更新数字
?
Handler myHandler = new Handler() { public void handleMessage(Message msg) { switch (msg.what) { case Main.NOTICE_COUNTER_MESSAGE_WHAT: int counter = msg.getData().getInt("counter", 0); if (counter == 0) { noticeCountText.setVisibility(View.GONE); } else { noticeCountText.setText("" + counter); noticeCountText.setVisibility(View.VISIBLE); } break; } super.handleMessage(msg); } }; private void updateNoticeCounter() { new Thread(new Runnable() { @Override public void run() { while (!Thread.currentThread().isInterrupted()) { Message message = new Message(); message.what = Main.NOTICE_COUNTER_MESSAGE_WHAT; Bundle data = new Bundle(); data.putInt("counter", NoticeHolder.getNoticeInfos().size()); message.setData(data); myHandler.sendMessage(message); try { Thread.sleep(100); } catch (InterruptedException e) { Thread.currentThread().interrupt(); } } } }).start(); } 1 楼 bsand 2012-03-15
