MainActivity代码：

import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.view.Window;public class MainActivity extends AppCompatActivity {    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestWindowFeature(Window.FEATURE_NO_TITLE);        setContentView(R.layout.splash);    }}

activity_main.xml代码：

<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:layout_width="match_parent"    android:gravity="center"    android:layout_height="match_parent">    <TextView        android:text="你好"        android:layout_width="wrap_content"        android:layout_height="wrap_content" /></LinearLayout>

splash.xml布局代码：

<FrameLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/mainFrame"    android:layout_width="match_parent"    android:layout_height="match_parent"    android:background="#ffffff" >    <include        android:id="@+id/include_main"        layout="@layout/activity_main" />    <com.zhjy.splashdt.PullDoorView        android:id="@+id/myImage"        android:layout_width="match_parent"        android:layout_height="match_parent"        android:background="#ddd" >        <TextView            android:id="@+id/tv_hint"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:layout_alignParentBottom="true"            android:layout_centerHorizontal="true"            android:layout_marginBottom="10dp"            android:text="上滑可以进入首页"            android:textColor="#ffffffff"            android:textSize="18sp" />    </com.zhjy.splashdt.PullDoorView></FrameLayout>
