[Java][Android] floating layout 라이브러리 사용해보기

안녕하세요. 오늘은 floating layout 를 사용해보도록 하겠습니다.

 

floating layout 라이브러리를 통해서, 다른 앱 위에서도 창을 띄워볼수 있습니다.

 

gradle 설정

allprojects {
    repositories {
        maven { url "https://jitpack.io" }
    }
}

dependencies {
    implementation 'com.github.HamedTaherpour:floating-layout-android:1.1.5'
}

Mainfest 설정

<uses-permission android:name="android.permission.SYSTEM_ALERT_WINDOW" />

<application>
    <service android:name="io.hamed.floatinglayout.service.FloatingService"/>
</application>

 

MainActivity.java

import androidx.appcompat.app.AppCompatActivity;

import android.content.Intent;
import android.net.Uri;
import android.os.Build;
import android.os.Bundle;
import android.provider.Settings;
import android.view.View;
import android.widget.Button;
import android.widget.Toast;

import io.hamed.floatinglayout.callback.FloatingListener;
import io.hamed.floatinglayout.FloatingLayout;

public class MainActivity extends AppCompatActivity {

    private FloatingLayout floatingLayout; // floating layout 선언
    private FloatingListener floatingListener = new FloatingListener() {
        @Override
        public void onCreateListener(View view) {
            Button btn = view.findViewById(R.id.btn_close);
            btn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    floatingLayout.destroy();
                }
            });
        } // floating layout 내부 레이아웃 설정

        @Override
        public void onCloseListener() {
            Toast.makeText(getApplicationContext(), "Close", Toast.LENGTH_SHORT).show();
        }
    };

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
    }

    public void onClick(View view) {
        switch (view.getId()) {
            case R.id.btn_open:
                if (!isNeedPermission())
                    showFloating();
                break;
            case R.id.btn_permission:
                if (isNeedPermission())
                    requestPermission();
                break;
        }
    } // 버튼 클릭 이벤트

    private boolean isNeedPermission() {
        return Build.VERSION.SDK_INT >= Build.VERSION_CODES.M && !Settings.canDrawOverlays(this);
    } // 다른 앱 위에서 작동이 가능하게 허용

    private void requestPermission() {
        Intent intent = new Intent(
                Settings.ACTION_MANAGE_OVERLAY_PERMISSION,
                Uri.parse("package:" + getPackageName())
        );
        startActivityForResult(intent, 25);
    } // overlay permission 요청

    private void showFloating() {
        floatingLayout = new FloatingLayout(this, R.layout.sample_layout);
        floatingLayout.setFloatingListener(floatingListener);
        floatingLayout.create();
    } // floating layout 실행
}

다른 앱 위에서 작동되기 위해서 권한 설정이 우선적으로 필요하다.
