Usage

Android

  • MainActivity.java File
...
import com.taumu.rnDynamicSplash.DynamicSplash;
import com.taumu.rnDynamicSplash.utils.Config;

public class MainActivity extends ReactActivity {
    ...
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Config splashConfig = new Config();  // Splash configuration class
        // splashConfig.setImageUrl("http://custom/splash.png");
        splashConfig.setAutoHide(true);
        // splashConfig.setAutoHideTime(2000);
        // splashConfig.setLayoutResID(R.layout.custom_splash_dynamic);
        // splashConfig.setThemeResId(R.style.Custom_Splash_Theme);
        // splashConfig.setAutoDownload(false);
        // splashConfig.setSplashSavePath("/customSplashPath/");
        // splashConfig.setDynamicShow(false);
        new DynamicSplash(this, splashConfig);  // Add display splash here
        super.onCreate(savedInstanceState);
    }
    ...
}

iOS

  • AppDelegate.m File
...
#import "RNDynamicSplash.h"
#import "SplashConfig.h"

@implementation AppDelegate

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
  ...
  [self.window makeKeyAndVisible];

  SplashConfig *config = [[SplashConfig alloc] init];  // Splash configuration class
  // config.imageUrl = @"http://custom/splash.png";
  config.autoHide = true;
  // config.autoHideTime = 1000;
  // config.dynamicShow = false;
  // config.autoDownload = false;
  // config.splashSavePath = @"custom";
  [[RNDynamicSplash alloc] initWithShow:rootView splashConfig:config];  // Add display splash here

  return YES;
}

@end
...

Configuration

type Field defaultValue setter description
String imageUrl "" setImageUrl Download picture address
String splashSavePath /splash/ setSplashSavePath Save image address
int themeResId(Android only) R.style.DynamicSplash_Theme setThemeResId Use theme resource id
int layoutResId(Android only) R.layout.splash_dynamic setLayoutResId Use layout file resource id
boolean autoDownload true setAutoDownload Whether to download automatically
boolean dynamicShow true setDynamicShow Whether to display the downloaded picture
boolean autoHide false setAutoHide Whether to automatically hide
long autoHideTime 3000 setAutoHideTime Automatically hide time

Other instructions

  • The first time to start displaying the default image, the second time to start displaying the downloaded image again
  • Android Can use their own written resource files and topics, and the same name as the default configuration, otherwise call the set method to change the configuration, reference package resource file
  • Android doesn't set imageUrl to show resource image in layout file
  • ios does not set imageUrl to show picture of LaunchImage

Provide get request method

Can call the request to get the address of the picture

// mock json data
// {
//     splashInfo: {
//         imageUrl: "http://***.png"
//     }
// }
...
import com.taumu.rnDynamicSplash.utils.HttpUtils;

public static void getSplashImageUrl(String getApi) {
    HttpUtils.get(getApi, new HttpUtils.Callback() {
        @Override
        public void onResponse(String jsonString) {
            try {
                JSONObject jsonObject = new JSONObject(jsonString);
                JSONObject valueObject = jsonObject.getJSONObject("splashInfo");
                String imageUrl = valueObject.getString("imageUrl");
                if (!TextUtils.isEmpty(imageUrl)) {
                    Config splashConfig = new Config();
                    splashConfig.setImageUrl(imageUrl);
                    new DynamicSplash(activity, splashConfig);
                }
            } catch (JSONException e) {
                e.printStackTrace();
            }
        }
    });
}
