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:


xmlns:android="http://schemas.android.com/apk/res/android"

android:id="@+id/activity_splash"

android:layout_width="match_parent"

android:layout_height="match_parent"

>

android:background="@mipmap/splash"

android:layout_width="match_parent"

android:layout_height="match_parent"/>

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();


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();

}


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();

}

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();

}


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。
