首先来看看拨号界面的配置代码：
<LinearLayout 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" android:background="@color/transparent" android:orientation="horizontal" tools:context="im.yixin.home.dial.DialFragment"> <FrameLayout android:id="@+id/dial_pan" android:layout_width="0dp" android:layout_height="match_parent" android:layout_weight="1"> </FrameLayout> <FrameLayout android:id="@+id/contact_pan" android:layout_width="0dp" android:layout_height="match_parent" android:layout_marginLeft="@dimen/gap_12_dp" android:layout_weight="3"></FrameLayout> </LinearLayout>
对应的界面代码如下：
public class DialFragment extends Fragment{
public DialFragment() {
// Required empty public constructor
}
/**
* Use this factory method to create a new instance of
* this fragment using the provided parameters.
*
* @return A new instance of fragment DialFragment.
*/
public static DialFragment newInstance() {
DialFragment fragment = new DialFragment();
return fragment;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
return inflater.inflate(R.layout.fragment_dial, container, false);
}
@Override
public void onActivityCreated(Bundle savedInstanceState) {
super.onActivityCreated(savedInstanceState);
addFragments();;
}
private void addFragments() {
FragmentTransaction transaction = getChildFragmentManager().beginTransaction();
transaction.replace(R.id.dial_pan, new DialPanFragment());
VerticalGridFragment fragment = new VerticalGridFragment();
Bundle args = new Bundle();
args.putInt(Extra.COLUMNS, Extra.DIAL_COLUMNS);
fragment.setArguments(args);
transaction.replace(R.id.contact_pan, fragment);
transaction.commit();
}
}拨号界面被分成了两部分，一部分为拨号盘，一部分为联系人，分别占据了屏幕一份和三份，右边的联系人与主界面的好用共用了同一个Fragment，因此这里我们再看看接下来的两个界面，首先我们看看拨号盘的界面代码。
由于只做展示，因此代码写的很粗糙，界面直接写了N个按钮的代码，配置界面如下：
<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" android:background="@color/white_35_transparent" android:clickable="true" android:contextClickable="true" android:orientation="vertical" tools:context="im.yixin.home.dial.DialFragment"> <ImageView android:id="@+id/dial_icon" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentBottom="true" android:layout_centerHorizontal="true" android:layout_marginBottom="@dimen/gap_20_dp" android:focusable="true" android:padding="@dimen/gap_20_dp" android:src="@drawable/tv_call_btn_selector"/> <LinearLayout android:id="@+id/input_num_line_1" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_above="@id/dial_icon" android:baselineAligned="false" android:orientation="horizontal"> <RelativeLayout android:layout_width="0dp" android:layout_height="80dp" android:layout_weight="1" android:background="@drawable/keyboard_item_selector"> <ImageView android:id="@+id/input_key_number_null" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_centerInParent="true" android:contentDescription="@string/empty"/> </RelativeLayout> <RelativeLayout android:layout_width="0dp" android:layout_height="80dp" android:layout_weight="1"> <TextView android:id="@+id/input_key_number_0" android:layout_width="60dp" android:layout_height="60dp" android:layout_centerInParent="true" android:background="@drawable/keyboard_item_selector" android:focusable="true" android:gravity="center" android:text="0" android:textColor="#ffffff" android:textSize="30sp"/> </RelativeLayout> <RelativeLayout android:layout_width="0dp" android:layout_height="80dp" android:layout_weight="1"> <ImageView android:id="@+id/input_key_number_del" android:layout_width="60dp" android:layout_height="60dp" android:layout_centerInParent="true" android:background="@drawable/keyboard_item_selector" android:contentDescription="@string/empty" android:focusable="true" android:scaleType="center" android:src="@drawable/tv_del"/> </RelativeLayout> </LinearLayout> <LinearLayout android:id="@+id/input_num_line_2" android:layout_width="fill_parent" android:layout_height="wrap_content" android:layout_above="@+id/input_num_line_1" android:baselineAligned="false" android:orientation="horizontal"> <RelativeLayout android:layout_width="0dp" android:layout_height="80dp" android:layout_weight="1"> <TextView android:id="@+id/input_key_number_7" android:layout_width="60dp" android:layout_height="60dp" android:layout_centerInParent="true" android:background="@drawable/keyboard_item_selector" android:focusable="true" android:gravity="center" android:text="7" android:textColor="#ffffff" android:textSize="30sp"/> </RelativeLayout> <RelativeLayout android:layout_width="0dp" android:layout_height="80dp" android:layout_weight="1"> <TextView android:id="@+id/input_key_number_8" android:layout_width="60dp" android:layout_height="60dp" android:layout_centerInParent="true" android:background="@drawable/keyboard_item_selector" android:focusable="true" android:gravity="center" android:text="8" android:textColor="#ffffff" android:textSize="30sp"/> </RelativeLayout> <RelativeLayout android:layout_width="0dp" android:layout_height="80dp" android:layout_weight="1"> <TextView android:id="@+id/input_key_number_9" android:layout_width="60dp" android:layout_height="60dp" android:layout_centerInParent="true" android:background="@drawable/keyboard_item_selector" android:focusable="true" android:gravity="center" android:text="9" android:textColor="#ffffff" android:textSize="30sp"/> </RelativeLayout> </LinearLayout>
