在我的应用程序代码中进行更改并且我的应用程序被重新编译后，我遇到了一个奇怪的问题... onPause活动生命周期方法在从最初运行大约20秒后第二次运行...有没有人遇到过类似的问题？
两次调用onPause的活动：
public class LoginActivity extends AppCompatActivity implements NetworkStateListeners, LoginActivityCommonElementsAndMuchMore {
private static final String debugTag = LoginActivity.class.getSimpleName();
private SpannableStringBuilder spannableStringBuilder;
private StyleSpan styleSpan;
private SignInFragment signInFragment;
private RegisterFragment registerFragment;
private ForgotPasswordFragment forgotPasswordFgmt;
private ClickableSpan clickableSpan;
private Bundle loginActivityBundle;
private int connectionStatus;
private NetworkState networkState;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
Log.e(debugTag, "onCreate");
setContentView(R.layout.login_activity);
if ( savedInstanceState == null ) {
networkState = new NetworkState();
loginActivityBundle = new Bundle();
signInFragment = new SignInFragment();
signInFragment.setArguments(loginActivityBundle);
getSupportFragmentManager().beginTransaction()
.replace(R.id.frame_container, signInFragment, getResources().getString(R.string.signInFgmt))
.commit();
getSupportFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
@Override
public void onBackStackChanged() {
Log.d(debugTag, "BACK STACK CHANGED!");
Log.d(debugTag, "BACK STACK COUNT: " + getSupportFragmentManager().getBackStackEntryCount());
for (int i = 0; i < getSupportFragmentManager().getBackStackEntryCount(); i++) {
Log.d(debugTag, "BACK STACK ENTRIES: " + getSupportFragmentManager().getBackStackEntryAt(i).getName());
}
}
});
}
}
@Override
protected void onResume() {
super.onResume();
Log.e(debugTag, "onResume");
networkState.addListener(this);
registerReceiver(networkState, new IntentFilter(getResources().getString(R.string.connectivity_change)));
}
@Override
protected void onPause() {
super.onPause();
Log.e(debugTag, "onPause");
networkState.removeListener(this);
unregisterReceiver(networkState);
int x = 10;
}
@Override
protected void onDestroy() {
super.onDestroy();
RefWatcher refWatcher = MyApplication.getRefWatcher(this);
refWatcher.watch(this);
}
@Override
public void onBackPressed() {
super.onBackPressed();
if ( getSupportFragmentManager().getBackStackEntryCount() > 0 ) getSupportFragmentManager().popBackStack(0, 0);
}
@Override
public void setLoginActivitySpan(TextView textView, String stringResource, int start, int end, final int code) {
spannableStringBuilder = new SpannableStringBuilder(stringResource);
styleSpan = new StyleSpan(Typeface.BOLD);
clickableSpan = new ClickableSpan() {
@Override
public void onClick(View widget) {
}
};
spannableStringBuilder.setSpan(clickableSpan, start, end, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
spannableStringBuilder.setSpan(styleSpan, start, end, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
spannableStringBuilder.setSpan(new ForegroundColorSpan(ContextCompat.getColor(getApplicationContext(), R.color.loginSpanColor)), start, end, Spannable.SPAN_INCLUSIVE_EXCLUSIVE);
textView.setText(spannableStringBuilder);
}
@Override
public void forgotPasswordOnClick() {
forgotPasswordFgmt = new ForgotPasswordFragment();
forgotPasswordFgmt.setArguments(loginActivityBundle);
getSupportFragmentManager().beginTransaction()
.replace(R.id.frame_container, forgotPasswordFgmt, getResources().getString(R.string.forgotPasswordFgmt))
.addToBackStack(getResources().getString(R.string.forgotPasswordFgmt))
.commit();
}
@Override
public void registerOnClick() {
registerFragment = new RegisterFragment();
if ( getSupportFragmentManager().getBackStackEntryCount() > 0 ) getSupportFragmentManager().popBackStack();
loginActivityBundle.putInt("connectivityStatus", connectionStatus);
registerFragment.setArguments(loginActivityBundle);
getSupportFragmentManager().beginTransaction()
.replace(R.id.frame_container, registerFragment, getResources().getString(R.string.registerFgmt))
.addToBackStack(getResources().getString(R.string.registerFgmt))
.commit();
}
@Override
public void signInHereOnClick() {
if (getSupportFragmentManager().getBackStackEntryCount() > 0) getSupportFragmentManager().popBackStack();
}
public static SharedPreferences getSessionPrefs(Context context) {
//Mode private so only this app can modify this SharedPreferences file
SharedPreferences sessionPrefs = context.getSharedPreferences(AppConfig.SESSION_PREFS, Context.MODE_PRIVATE);
return sessionPrefs;
}
@Override
public boolean validateEditText(EditText[] fields) {
for (EditText field : fields) {
if (field.getText().toString().isEmpty() && field.getTag().equals(getResources().getString(R.string.required))) return false;
}
return true;
}
@Override
public String encodeUtf8(String text) {
try {
byte[] data = text.getBytes("UTF-8");
return Base64.encodeToString(data, Base64.DEFAULT);
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
return null;
}
}
@Override
public String decodeUtf8(String text) {
try {
byte[] data = Base64.decode(text, Base64.DEFAULT);
return new String(data, "UTF-8");
} catch (UnsupportedEncodingException e) {
e.printStackTrace();
return null;
}
}
@Override
public void networkStatus(int connectionType) {
Log.e(debugTag, "listeners: "+connectionType);
connectionStatus = connectionType;
Intent intent = new Intent(getResources().getString(R.string.network_state_update));
intent.putExtra(getResources().getString(R.string.connectivity_status), connectionStatus);
LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(intent);
}
}
logcat的：
