package fragment.example.com.fragmenttest;

public class MainActivity extends AppCompatActivity implements View.OnClickListener {
@Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button button = (Button) findViewById(R.id.button);
button.setOnClickListener(this);
replaceFragment(new RightFragment());
}
@Override
public void onClick(View v){
switch (v.getId()){
case R.id.button:
replaceFragment(new AnotherRightFragment());
break;
default:break;
}
}
private void replaceFragment(Fragment fragment) {
FragmentManager fragmentManager = getSupportFragmentManager();
FragmentTransaction transaction = fragmentManager.beginTransaction();
transaction.replace(R.id.right_layout,fragment);
transaction.commit();
}
}
报错位置是 transaction.replace(R.id.right_layout,fragment);的fragment
