Source Code

使用兩個 Activity 和 Fragment 互傳做測試；另外並沒有使用 Support Library，以下為原始碼：

Main.java

public class Main extends Activity {
    private static final String TAG = Main.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Log.d(TAG, "onCreate");
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        if (savedInstanceState == null) {
            getFragmentManager().beginTransaction()
                                .add(R.id.container, new MainFragment())
                                .commit();
        }
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        Log.d(TAG, "onSaveInstanceState");
        super.onSaveInstanceState(outState);
    }

    @Override
    protected void onPause() {
        Log.d(TAG, "onPause");
        super.onPause();
    }

    @Override
    protected void onStop() {
        Log.d(TAG, "onStop");
        super.onStop();
    }

    @Override
    protected void onDestroy() {
        Log.d(TAG, "onDestroy");
        super.onDestroy();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        Log.d(TAG, "onConfigurationChanged");
        super.onConfigurationChanged(newConfig);
    }

    @Override

        Log.d(TAG, "onPostResume");
        super.onPostResume();
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        Log.d(TAG, "onPostCreate");
        super.onPostCreate(savedInstanceState);
    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        Log.d(TAG, "onRestoreInstanceState");
        super.onRestoreInstanceState(savedInstanceState);
    }

    @Override
    public void onAttachFragment(Fragment fragment) {
        Log.d(TAG, "onAttachFragment");
        super.onAttachFragment(fragment);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        Log.d(TAG, "onActivityResult, requestCode: " + requestCode + " , resultCode: " + resultCode);
        super.onActivityResult(requestCode, resultCode, data);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        Log.d(TAG, "onCreateOptionsMenu");
        getMenuInflater().inflate(R.menu.main, menu);
        return true;
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {
        Log.d(TAG, "onPrepareOptionsMenu");
        return super.onPrepareOptionsMenu(menu);
    }
}

Sub.java

public class Sub extends Activity {
    private static final String TAG = Sub.class.getSimpleName();

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        Log.d(TAG, "onCreate");
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_sub);

        if (savedInstanceState == null) {
            getFragmentManager().beginTransaction()
                                .add(R.id.container, new SubFragment())
                                .commit();
        }
    }

    @Override
    protected void onSaveInstanceState(Bundle outState) {
        Log.d(TAG, "onSaveInstanceState");
        super.onSaveInstanceState(outState);
    }

    @Override
    protected void onPause() {
        Log.d(TAG, "onPause");
        super.onPause();
    }

    @Override
    protected void onStop() {
        Log.d(TAG, "onStop");
        super.onStop();
    }

    @Override
    protected void onDestroy() {
        Log.d(TAG, "onDestroy");
        super.onDestroy();
    }

    @Override
    public void onConfigurationChanged(Configuration newConfig) {
        Log.d(TAG, "onConfigurationChanged");
        super.onConfigurationChanged(newConfig);
    }

    @Override
    protected void onRestart() {
        Log.d(TAG, "onRestart");
        super.onRestart();
    }

    @Override
    protected void onResume() {
        Log.d(TAG, "onResume");
        super.onResume();
    }

    @Override
    protected void onStart() {
        Log.d(TAG, "onStart");
        super.onStart();
    }

    @Override
    protected void onPostResume() {
        Log.d(TAG, "onPostResume");
        super.onPostResume();
    }

    @Override
    protected void onPostCreate(Bundle savedInstanceState) {
        Log.d(TAG, "onPostCreate");
        super.onPostCreate(savedInstanceState);
    }

    @Override
    protected void onRestoreInstanceState(Bundle savedInstanceState) {
        Log.d(TAG, "onRestoreInstanceState");
        super.onRestoreInstanceState(savedInstanceState);
    }

    @Override
    public void onAttachFragment(Fragment fragment) {
        Log.d(TAG, "onAttachFragment");
        super.onAttachFragment(fragment);
    }

    @Override
    protected void onActivityResult(int requestCode, int resultCode, Intent data) {
        Log.d(TAG, "onActivityResult, requestCode: " + requestCode + " , resultCode: " + resultCode);
        super.onActivityResult(requestCode, resultCode, data);
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        Log.d(TAG, "onCreateOptionsMenu");
        getMenuInflater().inflate(R.menu.sub, menu);
        return true;
    }

    @Override
    public boolean onPrepareOptionsMenu(Menu menu) {
        Log.d(TAG, "onPrepareOptionsMenu");
        return super.onPrepareOptionsMenu(menu);
    }

}

Main.java 和 Sub.java 的內容幾乎相同，只有套用的 layout 和呼叫 Fragment 不同。

以下為監看的Callback列表(按名稱排序)

public void onConfigurationChanged(Configuration newConfig)
protected void onCreate(Bundle savedInstanceState)
public boolean onCreateOptionsMenu(Menu menu)
protected void onDestroy()
protected void onPause()
protected void onPostCreate(Bundle savedInstanceState)
protected void onPostResume()
public boolean onPrepareOptionsMenu(Menu menu)
protected void onRestart()
protected void onRestoreInstanceState(Bundle savedInstanceState)
protected void onResume()
protected void onSaveInstanceState(Bundle outState)
protected void onStart()
protected void onStop()

Fragment 因 Button 不一樣，所以內容是 Button 的部分不同而已

而 Fragment 跟 Activity 要監聽的部分也有點不大一樣：

public void onActivityCreated(Bundle savedInstanceState)
public void onActivityResult(int requestCode, int resultCode, Intent data)
public void onAttach(Activity activity)
public void onConfigurationChanged(Configuration newConfig)
public void onCreate(Bundle savedInstanceState)
public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo)
public void onCreateOptionsMenu(Menu menu, MenuInflater inflater)
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState)
public void onDestroy()
public void onDestroyOptionsMenu()
public void onDestroyView()
public void onDetach()
public void onHiddenChanged(boolean hidden)
public void onPause()
public void onPrepareOptionsMenu(Menu menu)
public void onResume()
public void onSaveInstanceState(Bundle outState)
public void onStart()
public void onStop()
public void onViewCreated(View view, Bundle savedInstanceState)
public void onViewStateRestored(Bundle savedInstanceState) (此方法有API限制API Level 17 Required，不過低版本只會報警告，仍然可以繼續執行。)
