Android startup page effect display
When you usually open the app on your phone, a 3-second advertisement will pop up before you enter the app. Today we will simply implement the function of the guide page.
1. First, create a new activity page and name it: SplashActivity
Add the content of the startup page in activity_splash.xml, I added a picture here (the picture is placed under the drawable file), the code is as follows:
<?xml version="1.0" encoding="utf-8"?>
<androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="@drawable/zhz"
tools:context=".SplashActivity">
<ImageView
android:layout_width="match_parent"
android:layout_height="match_parent"
android:src="@drawable/zhz"></ImageView>
</androidx.constraintlayout.widget.ConstraintLayout>
In the java file, hide the status bar and title bar of the startup page, and set the display time of the startup page to 3 seconds.
SplashActivity.java code is as follows:
public class SplashActivity extends AppCompatActivity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
//隐藏状态栏
getWindow().addFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN);
//隐藏标题栏
getSupportActionBar().hide();
setContentView(R.layout.activity_splash);
//创建子线程
Thread mThread=new Thread(){
@Override
public void run() {
super.run();
try {
sleep(3000);//使程序休眠3秒
Intent intent=new Intent(getApplicationContext(),MainActivity.class);
startActivity(intent);
finish();
}catch (Exception e){
e.printStackTrace();
}
}
};
mThread.start();//启动线程
}
}
2. In the AndroidManifest.xml file, set the startup page to .SplashActivity, the code is as follows:
<activity android:name=".StartActivity">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
3. I have changed the application icon to my own picture here. You can change it according to your own needs (you can not change it), the code is as follows:
At this point, you have completed all the steps, run it and try it out!
The result of the operation is as follows:

Of course, you can also add more styles to the startup page according to your own needs, come on!
