做一个APP，首先是它的首页，给人一个品牌的形象，让人一眼就知道你的app做什么的。

先是主要代码：

1.activity主要代码

public class SplashActivity extends AppCompatActivity {    private boolean isNeedSetting;    private boolean isNeedLogin = true;    private boolean isFirstRun  = true;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        requestWindowFeature(Window.FEATURE_NO_TITLE);        getWindow().setFlags(WindowManager.LayoutParams.FLAG_FULLSCREEN,                WindowManager.LayoutParams.FLAG_FULLSCREEN);        setContentView(R.layout.activity_splash);        initData();        initConnect();        //  initGPS();    }

2.XML代码：

<?xml version="1.0" encoding="utf-8"?><RelativeLayoutxmlns:android="http://schemas.android.com/apk/res/android"android:id="@+id/activity_splash"android:layout_width="match_parent"android:layout_height="match_parent"    ><ImageView    android:background="@mipmap/splash"    android:layout_width="match_parent"    android:layout_height="match_parent"/></RelativeLayout>

3.initData()方法

    private void initData() {        isFirstRun = getSharedPreferences(MyConstains.SP_MOBIKE, MODE_PRIVATE).                getBoolean(IS_FIRST_RUN, true);        isNeedLogin = getSharedPreferences(MyConstains.SP_MOBIKE, MODE_PRIVATE).                getBoolean(MyConstains.IS_NEED_LOGIN, true);    }

4.initConnect()方法

private void initConnect() {        if (!isConn(this)) {            //提示对话框            AlertDialog.Builder builder = new AlertDialog.Builder(SplashActivity.this);            builder.setMessage("网络无法访问，请检查网络").setPositiveButton("确定",                    new DialogInterface.OnClickListener() {                        @Override                        public void onClick(DialogInterface dialog, int which) {                            Intent intent = null;                            //判断手机系统的版本  即API大于10 就是3.0或以上版本                            if (android.os.Build.VERSION.SDK_INT > 21) {                                intent = new Intent(Settings.ACTION_HOME_SETTINGS);                            } else {                                intent = new Intent();                                ComponentName component = new ComponentName("com.android.settings", "com.android.settings.WirelessSettings");                                intent.setComponent(component);                                intent.setAction("android.intent.action.VIEW");                            }                            startActivityForResult(intent, 1);                        }                    }).setNegativeButton("取消", new DialogInterface.OnClickListener() {                @Override                public void onClick(DialogInterface dialog, int which) {                    dialog.dismiss();                    finish();                }            }).show();        } else {            checkFirstRun();        }    }

5.判断网络是否正常

/**     * 判断网络连接是否已开     * true 已打开  false 未打开     */    public static boolean isConn(Context context) {        if (context != null) {            ConnectivityManager mConnectivityManager = (ConnectivityManager) context                    .getSystemService(Context.CONNECTIVITY_SERVICE);            NetworkInfo mNetworkInfo = mConnectivityManager.getActiveNetworkInfo();            if (mNetworkInfo != null) {                return mNetworkInfo.isAvailable();            }        }        return false;    }

6.判断GPS是否正常

 private void initGPS() {        LocationManager locationManager = (LocationManager) this                .getSystemService(Context.LOCATION_SERVICE);        // 判断GPS模块是否开启，如果没有则跳转至设置开启界面，设置完毕后返回到首页        if (!locationManager.isProviderEnabled(android.location.LocationManager.GPS_PROVIDER)) {            AlertDialog.Builder builder = new AlertDialog.Builder(SplashActivity.this);            builder.setTitle("GPS提示：");            builder.setMessage("请打开GPS开关，以便您更准确的找到自行车");            builder.setCancelable(false);            builder.setPositiveButton("确定",                    new android.content.DialogInterface.OnClickListener() {                        @Override                        public void onClick(DialogInterface arg0, int arg1) {                            // 转到手机设置界面，用户设置GPS                            Intent intent = new Intent(                                    Settings.ACTION_LOCATION_SOURCE_SETTINGS);                            startActivityForResult(intent, 2); // 设置完成后返回到原来的界面                        }                    });            builder.setNegativeButton("取消", new android.content.DialogInterface.OnClickListener() {                @Override                public void onClick(DialogInterface dialog, int which) {                    dialog.dismiss();                }            }).show();        }    }

7.跳转设置后重新判断

    @Override    protected void onResume() {        super.onResume();        if (isNeedSetting) {            if (isConn(this)) {                checkFirstRun();            } else {                initConnect();            }        }    }

8.判断是否第一次运行，如果是，跳转引导界面

 private void checkFirstRun() {        if (isFirstRun) {            Go2Guide();            getSharedPreferences(MyConstains.SP_MOBIKE, MODE_PRIVATE)                    .edit()                    .putBoolean(MyConstains.IS_FIRST_RUN, false)                    .apply();        } else {            new Handler().postDelayed(new Runnable() {                @Override                public void run() {                    if (isNeedLogin) {                        Go2Login();                    } else {                        Go2Main();                    }                }            }, 2000);        }    }

9.activity间的跳转

 private void Go2Login() {        Intent intent = new Intent(SplashActivity.this, LoginActivity.class);        startActivity(intent);        finish();    }    private void Go2Main() {        Intent intent = new Intent(SplashActivity.this, MainActivity.class);        startActivity(intent);        finish();    }    private void Go2Guide() {        Intent intent = new Intent(SplashActivity.this, GuideActivity.class);        startActivity(intent);        finish();    }

10.最后是跳转设置界面返回判断

 @Override    protected void onActivityResult(int requestCode, int resultCode, Intent data) {        switch (requestCode) {            case 1:            case 2:                isNeedSetting = true;                break;            default:                break;        }    }

首界面代码十分简单，主要判断网络，因为使用该APP必须联网的，最好是开GPS定位的，其次是延迟2S判断进入哪个页面。
