android APP 启动界面

新建一个开启界面的.Java文件

 

importandroid.app.Activity;

import android.content.Intent;

import android.os.Bundle;

import android.os.Handler;

import android.view.MotionEvent;

import android.view.Window;

import android.view.WindowManager;

public class activity_kaiji extends Activity {

    private Handlerhandler = newHandler();

    @Override
    public void onCreate(BundlesavedInstanceState) {

        super.onCreate(savedInstanceState);

//        NO Title
        requestWindowFeature(Window.FEATURE_NO_TITLE);

       getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,WindowManager.LayoutParams.FLAG_FULLSCREEN);

        setContentView(R.layout.kaiji);

//延时
        handler.postDelayed(newRunnable() {

            @Override
            public void run() {

//从该界面跳转到下一界面

                Intent intent = newIntent(activity_kaiji.this, MainActivity.class);

               startActivity(intent);

                //删除该开启界面
                finish();

                //界面时间
            }

        }, 1000);

    }

}

新建一个开启界面的.xml文件

修改AndroidFanifest文件

//开启界面的java文件放在前
<activity android:name=".activity_kaiji">
    <intent-filter>
        <action android:name="android.intent.action.MAIN"/>

        <category android:name="android.intent.category.LAUNCHER"/>
    </intent-filter>
</activity>

//下一个界面
<activity android:name=".MainActivity">


</activity>

就ok啦
