私はシンプルな360ビデオビューアを構築していますが、クラッシュしています。以下は
は、ユーザーがビュービデオをクリックしたときに、360ビデオが開く必要があります選択肢ページのコードです。
package com.example.jal.jp;
import android.content.Intent;
import android.os.Bundle;
import android.support.design.widget.FloatingActionButton;
import android.support.design.widget.Snackbar;
import android.support.v7.app.AppCompatActivity;

public class Choices extends AppCompatActivity {
public Button first_button;
//public Button second_button;
public void init(){
first_button = (Button)findViewById(R.id.video);
// second_button = (Button)findViewById(R.id.video);
first_button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
Intent view = new Intent(Choices.this,VR_Video.class);
startActivity(view);
}
});
/** second_button.setOnClickListener(new View.OnClickListener() {
