움직이는 로딩 이미지 AppCompatDiaLog + Lotti

1. BaseApplication 클래스에 AppCompatDialog를 생성

public class BaseApplication extends Application {
 
    private static BaseApplication baseApplication;
    AppCompatDialog progressDialog;
 
    public static BaseApplication getInstance() {
        return baseApplication;
    }
 
    @Override
    public void onCreate() {
        super.onCreate();
        baseApplication = this;
    }
 
    public void progressON(Activity activity, String message) {
        if (activity == null) {
            return;
        }
        if (progressDialog != null && progressDialog.isShowing()) {
            progressSET(message);
        } else {
            progressDialog = new AppCompatDialog(activity);
            progressDialog.setCancelable(false);
            progressDialog.getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
            progressDialog.setContentView(R.layout.progress_loading);
            progressDialog.show();
        }
 
        final LottieAnimationView lottieAnimationView = (LottieAnimationView) progressDialog.findViewById(R.id.iv_frame_loading);
        lottieAnimationView.playAnimation();
 
 
        TextView tv_progress_message = (TextView) progressDialog.findViewById(R.id.tv_progress_message);
        if (!TextUtils.isEmpty(message)) {
            tv_progress_message.setText(message);
        }
    }
 
    public void progressSET(String message) {
        if (progressDialog == null || !progressDialog.isShowing()) {
            return;
        }
        TextView tv_progress_message = (TextView) progressDialog.findViewById(R.id.tv_progress_message);
        if (!TextUtils.isEmpty(message)) {
            tv_progress_message.setText(message);
        }
    }
 
    public void progressOFF() {
        if (progressDialog != null && progressDialog.isShowing()) {
            progressDialog.dismiss();
        }
    }
 
}

2. https://www.lottiefiles.com/ 에서 json 파일을 다운로드

assets Folder 생성한후 json 파일 붙여넣기

3 . res -> layout -> progress_loading.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:id="@+id/loading_frame_container"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent">
 
    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true"
        android:gravity="center"
        android:orientation="vertical">
 
        <com.airbnb.lottie.LottieAnimationView
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:id="@+id/iv_frame_loading"
            app:lottie_loop="true"
            app:lottie_fileName="loading.json"
            app:lottie_autoPlay="true"
            />
 
        <TextView
            android:id="@+id/tv_progress_message"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_marginTop="16dp"
            android:text="Loading.."
            android:textAppearance="?android:attr/textAppearanceLarge"
            android:textColor="#ffffff" />
    </LinearLayout>
</RelativeLayout>

fileName 설정 = json 파일 이름 

3. app gradle  dependencies 에 추가 -> sync 

compile 'com.airbnb.android:lottie:2.1.0'

4. Manifest 에 name 속성 추가

<application
    android:name=".BaseApplication"
    android:allowBackup="true"
    android:icon="@mipmap/icon"
    android:label="@string/app_name"
    android:roundIcon="@mipmap/icon"
    android:supportsRtl="true"
    android:theme="@style/AppTheme">

5. 로딩이 필요한 부분에 추가

BaseApplication.getInstance().progressON(MainActivity.this, null);

로딩 시작

BaseApplication.getInstance().progressOFF(); 

로딩 종료
