android自定义底部Tab，项目整体界面框架，靠着这份900多页的PDF面试整理

switch (mState) {

case 0:

mStateButton1.setSelected(true);

tag = mStateButton1.getTag();

break;

case 1:

mStateButton2.setSelected(true);

tag = mStateButton2.getTag();

break;

case 2:

mStateButton3.setSelected(true);

tag = mStateButton3.getTag();

break;

case 3:

mStateButton4.setSelected(true);

tag = mStateButton4.getTag();

break;

default:

break;

}

if (mOnTabChangedListener != null) {

if (tag != null && mOnTabChangedListener != null) {

mOnTabChangedListener.onTabChange(tag.toString());

} else {

mOnTabChangedListener.onTabChange(null);

}

} // else ignored

}

/* (non-Javadoc)

• @see android.view.View.OnClickListener#onClick(android.view.View)

*/

@Override

public void onClick(View v) {

// TODO Auto-generated method stub

switch (v.getId()) {

case R.id.button_state1:

switchState(0);

break;

case R.id.button_state2:

switchState(1);

break;

case R.id.button_state3:

switchState(2);

break;

case R.id.button_state4:

switchState(3);

break;

default:

break;

}

}

public static interface OnTabChangeListener {

public void onTabChange(String tag);

}

}

二、对应底部Tab的XML布局文件

---

<FrameLayout

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:layout_weight=“1.0” >

<Button

android:id=”@+id/button_state1″

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:background=”@null”

android:button=”@null”

android:drawableTop=”@drawable/ic_message_selector“

android:gravity=“center”

android:singleLine=“true”

android:tag=“message”

android:text=”@string/text_tab_message”

android:textColor=”@color/text_service_color“

android:textSize=“14dp” />

<FrameLayout

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:layout_weight=“1.0” >

<Button

android:id=”@+id/button_state2″

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:background=”@null”

android:button=”@null”

android:drawableTop=”@drawable/ic_service_selector“

android:gravity=“center”

android:singleLine=“true”

android:tag=“service”

android:text=”@string/text_tab_service“

android:textColor=”@color/text_service_color“

android:textSize=“14dp” />

<FrameLayout

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:layout_weight=“1.0” >

<Button

android:id=”@+id/button_state3″

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:background=”@null”

android:button=”@null”

android:drawableTop=”@drawable/ic_profile_selector“

android:gravity=“center”

android:singleLine=“true”

android:tag=“personal”

android:text=”@string/text_tab_profile“

android:textColor=”@color/text_service_color”

android:textSize=“14dp” />

<FrameLayout

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:layout_weight=“1.0” >

<Button

android:id=”@+id/button_state4″

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:background=”@null”

android:button=”@null”

android:drawableTop=”@drawable/ic_setting_selector“

android:gravity=“center”

android:singleLine=“true”

android:tag=“settings”

android:text=”@string/text_tab_sett
ing”

android:textColor=”@color/text_service_color”

android:textSize=“14dp” />

三、在启动的Acitvity界面中使用自定义的Tab类

---

<?xml version=”1.0″ encoding=”utf-8″?>

<LinearLayout xmlns:android=“http://schemas.android.com/apk/res/android”

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:orientation=“vertical” >

<FrameLayout

android:id=”@+id/layout_content“

android:layout_width=“match_parent”

android:layout_height=“match_parent”

android:layout_weight=“1.0” />

<app.ui.widget.TabView

android:id=”@+id/view_tab“

android:layout_width=“match_parent”

android:layout_height=”@dimen/header_height”

android:background=”@color/tab_main_color” />

四、自定义类处理Fragment返回重叠的问题
