一个片段中的SherlcokFargments按钮调用第二个片段

Question

我在弄清楚碎片是如何工作的。我有3个类，MainActivity，Fragment1和fragment2。

MainActivity扩展了

    @Override
    public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    Fragment1 firstFragment = new Fragment1();
    firstFragment.setArguments(getIntent().getExtras());
    getSupportFragmentManager().beginTransaction()
                .add(R.id.fragment_container1, firstFragment).commit();

public View onCreateView(LayoutInflater inflater, ViewGroup container,
        Bundle savedInstanceState) {

    return inflater.inflate(R.layout.fragment1layout, container, false);

Fragment2还扩展了SherlockFragment，但什么也不做，将它膨胀为空。xml

Answer 1

您必须从fragment1调用fragment2，如下所示

  public View onCreateView(LayoutInflater inflater, ViewGroup container,
            Bundle savedInstanceState) {
     View view = inflater.inflate(R.layout.fragment1layout, container, false);
            Button button = (Button)view.findViewById(R.id.yourButton);
            button.setOnClickListener(new OnClickListener() {

                @Override
                public void onClick(View v) {
                    //Replace your fragment

                }
            });
        return view;
}
