PreferenceFragmentを追加

MainActivity.java

import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;

import com.kaji.fragmentmyapplication.ui.main.MainFragment;

public class MainActivity extends AppCompatActivity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main_activity);
        if (savedInstanceState == null) {
            getSupportFragmentManager().beginTransaction()
                    .replace(R.id.container, MainFragment.newInstance())
                    .commitNow();
        }
    }
}

build.gradleに以下を追加

dependencies {
    implementation 'com.android.support:appcompat-v7:28.0.0'
    implementation 'com.android.support:preference-v7:28.0.0'
}
