Android仿qq顶部消息栏效果
作者:cf8833 时间:2021-10-28 13:52:57
android仿照qq的顶部栏效果,主要就是利用fragment manager把fragment设置显示内容
(1)在activity_main.xml布局中添加控件
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent">
<LinearLayout
android:id="@+id/ll_qqtop"
android:layout_width="match_parent"
android:layout_height="50dp"
android:orientation="horizontal"
android:gravity="center"
android:background="@color/whites">
<LinearLayout
android:id="@+id/common_constact"
android:layout_height="40dp"
android:layout_width="150dp"
android:orientation="horizontal"
android:layout_centerHorizontal="true"
android:layout_alignParentTop="true">
<Button
android:id="@+id/constact_group"
android:layout_height="match_parent"
android:layout_width="0dp"
android:layout_weight="1"
android:padding="5dp"
android:textSize="16sp"
android:button="@null"
android:checked="true"
android:background="@drawable/qq_contact_group"
android:textColor="@drawable/qq_constact_font"
android:text="消息"/>
<Button
android:button="@null"
android:id="@+id/constact_all"
android:layout_width="0dp"
android:layout_height="match_parent"
android:layout_weight="1"
android:textSize="16sp"
android:padding="5dp"
android:background="@drawable/qq_contact_all"
android:textColor="@drawable/qq_constact_font"
android:text="电话"/>
</LinearLayout>
</LinearLayout>
<FrameLayout
android:id="@+id/id_content"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:layout_below="@+id/ll_qqtop" />
</RelativeLayout>
(2)在drawable中添加样式文件,包括字体颜色和背景
2.1.在drawable文件夹中新建一个文件:qq_contact_group.xml,这个是左边按钮的背景样式xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false"><shape>
<corners android:bottomLeftRadius="5dp" android:bottomRightRadius="0dp" android:topLeftRadius="5dp" android:topRightRadius="0dp" />
<solid android:color="@color/blue" />
<stroke android:width="1dp" android:color="@color/blue" />
</shape>
</item>
<item android:state_pressed="true"><shape>
<corners android:bottomLeftRadius="5dp" android:bottomRightRadius="0dp" android:topLeftRadius="5dp" android:topRightRadius="0dp" />
<solid android:color="@color/whites" />
<stroke android:width="1dp" android:color="@color/whites" />
</shape>
</item>
<item><shape>
<corners android:bottomLeftRadius="5dp" android:bottomRightRadius="0dp" android:topLeftRadius="5dp" android:topRightRadius="0dp" />
<solid android:color="@color/whites" />
<stroke android:width="1dp" android:color="@color/blue" />
</shape>
</item>
</selector>
2.2在drawable文件夹中新建一个文件:qq_contact_all.xml,这个是右边按钮的背景样式xml
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
<item android:state_enabled="false"><shape>
<corners android:bottomLeftRadius="0dp" android:bottomRightRadius="5dp" android:topLeftRadius="0dp" android:topRightRadius="5dp" />
<solid android:color="@color/blue" />
<stroke android:width="1dp" android:color="@color/blue" />
</shape>
</item>
<item android:state_pressed="true"><shape>
<corners android:bottomLeftRadius="0dp" android:bottomRightRadius="5dp" android:topLeftRadius="0dp" android:topRightRadius="5dp" />
<solid android:color="@color/blue" />
<stroke android:width="1dp" android:color="@color/blue" />
</shape>
</item>
<item><shape>
<corners android:bottomLeftRadius="0dp" android:bottomRightRadius="5dp" android:topLeftRadius="0dp" android:topRightRadius="5dp" />
<solid android:color="@color/whites" />
<stroke android:width="1dp" android:color="@color/blue" />
</shape>
</item>
</selector>
3.在drawable文件夹中新建一个文件:qq_constact_font.xml,这个是两个按钮的文字样式xml,不选中为白色,选中为蓝色
<?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android" >
<item android:state_pressed="true" android:color="@color/whites"/>
<item android:state_enabled="false" android:color="@color/whites"/>
<item android:color="@color/blue"/>
</selector>
(3)在MainActivity中设置按钮的选中情况,并且在fragmentManager中调用fragment
public class MainActivity extends Activity implements View.OnClickListener {
//参考网址:https://blog.csdn.net/u010585448/article/details/48543883
private Button title_left_btn , title_right_btn;
/**
* Fragment管理器
*/
private android.app.FragmentManager mFragmentManager;
private FragmentTransaction mTransaction;
/**
* 两个Fragment
*/
private LeftFragment mLFragment ;
private RightFragment mRFragment;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
initView();
}
private void initView() {
// TODO Auto-generated method stub
title_left_btn = (Button)findViewById(R.id.constact_group);
title_right_btn = (Button)findViewById(R.id.constact_all);
title_left_btn.setOnClickListener(this);
title_left_btn.performClick();//模拟点击事件,使左边按钮被点击
mFragmentManager = getFragmentManager();
mTransaction = mFragmentManager.beginTransaction();
mLFragment = new LeftFragment();
mTransaction.replace(R.id.id_content, mLFragment);
mTransaction.commit();
title_right_btn.setOnClickListener(this);
}
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
switch (v.getId()) {
case R.id.constact_group:
if(title_left_btn.isEnabled()){
title_left_btn.setEnabled(false);
title_right_btn.setEnabled(true);
}
mFragmentManager = getFragmentManager();
mTransaction = mFragmentManager.beginTransaction();
if(mLFragment == null){
mLFragment = new LeftFragment();
}
mTransaction.replace(R.id.id_content, mLFragment);
mTransaction.commit();
break;
case R.id.constact_all:
if(title_right_btn.isEnabled()){
title_left_btn.setEnabled(true);
title_right_btn.setEnabled(false);
}
mFragmentManager = getFragmentManager();
mTransaction = mFragmentManager.beginTransaction();
if(mRFragment == null){
mRFragment = new RightFragment();
}
mTransaction.replace(R.id.id_content, mRFragment);
mTransaction.commit();
break;
}
}
}
最后,简单贴一下fragment吧
public class LeftFragment extends android.app.Fragment {
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
return inflater.inflate(R.layout.left_fragment, container , false);
}
}
