每日学习

今天准备开始做团队作业。

首先做的是进入app时的动画页面：

动画页面布局

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:layout_width="match_parent"
    android:layout_height="match_parent">
    <ImageView
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:background="@mipmap/first"
        />
</RelativeLayout>

 java代码：

package com.example.bowenwang;

import androidx.annotation.RequiresApi;
import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.graphics.Color;
import android.os.Build;
import android.os.Bundle;
import android.view.View;
import android.view.WindowManager;

import java.util.Timer;
import java.util.TimerTask;

public class firstActivity extends AppCompatActivity {

    @RequiresApi(api = Build.VERSION_CODES.LOLLIPOP)
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_first);

        this. getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,
                WindowManager.LayoutParams.FLAG_FULLSCREEN);
        Timer timer = new Timer();
        TimerTask task = new TimerTask() {
            @Override
            public void run() {
                Intent intent = new Intent(firstActivity.this, MainActivity.class);
                startActivity(intent);
                firstActivity.this.finish();
            }
        };
        getWindow().setStatusBarColor(Color.TRANSPARENT);
        getWindow().getDecorView().setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_FULLSCREEN);
        timer.schedule(task, 3000);
    }
}
