我希望你能帮助我,一旦我通过工具栏中的(弹出)菜单选项退出我的应用程序,我就会有一个泄露的窗口.如果我通过正常方法退出应用程序一切都很好.
有人可能会帮忙吗？我似乎无法找到错误,我正在努力找到一个合适的解决方案.我有2个静态字符串变量声明,但我想这不是问题.
许多事先提前.
以下是菜单的相关代码:
public class LoginActivity extends AppCompatActivity {
//
private Object mState = null;
private Object HIDE_MENU = null;
//
@Override
protected void onCreate(Bundle savedInstanceState) {
//
@Override
public boolean onCreateOptionsMenu(Menu menu) {
// inflate menu from xml
MenuInflater mInflater = this.getMenuInflater();
mInflater.inflate(R.menu.menu_main, menu);
if (mState == HIDE_MENU) {
menu.getItem(0).setVisible(false);
}
return true;
}
@Override
public boolean onOptionsItemSelected(MenuItem item) {
switch (item.getItemId()) {
case R.id.settings:
// Unassigned
return true;
case R.id.exit:
this.finish(); …我oAuth在应用程序中使用Twitter 库。用户使用Twitter帐户登录。
在活动A中，可以使用Twitter登录。用户登录后，我想启动没有历史记录的活动B。这是我所有的东西：
首先，，Manifest.xml因此我设置launchMode=singleTask为Twitter api请求：
<activity
android:name=".A_Activity"
android:label="@string/app_name"
android:launchMode="singleTask"
android:theme="@android:style/Theme.Black.NoTitleBar">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
<intent-filter>
<action android:name="android.intent.action.VIEW" />
<category android:name="android.intent.category.DEFAULT" />
<category android:name="android.intent.category.BROWSABLE" />
<data android:scheme="my_twitter_scheme" />
</intent-filter>
</activity>
这是我开始活动B的方式：
Intent i = new Intent(A.this, B.class);
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
context.startActivity(i);
注意：我正在通过BroadcastReceiver实例调用活动B。
当我登录时，我的接收器正确地开始了活动B，但是不幸的是，当我按下“后退”按钮时，应用程序又回到了活动A。
我想这差不多了launchMode，正如我所说，Twitter需要这种选择。我究竟做错了什么？任何帮助或建议（也许关于Twitter）都将是很棒的。
我已经解析了JSON数据listview,现在我想让它可以离线使用.有没有办法在手机上保存JSON数据,以便在手机离线时可以看到数据？
有人知道一个例子吗？
编辑现在工作:
public class MainActivity extends ListActivity {
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
new TheTask().execute();
}
class TheTask extends AsyncTask<Void, Void, JSONArray> {
InputStream is = null;
String result = "";
JSONArray jArray = null;
ProgressDialog pd;
@Override
protected void onPostExecute(JSONArray result) {
super.onPostExecute(result);
pd.dismiss();
ArrayList<String> list= new ArrayList<String>();
try {
for(int i=0;i<result.length();i++) {
JSONObject jb = result.getJSONObject(i) ;
String name = jb.getString("name")+" "+jb.getString("Art");
list.add(name);
}
} catch(Exception e) {
e.printStackTrace();
}

请参考以下代码并告诉我一些变化
以下是LoginActivity
public class LoginActivity extends SherlockActivity {
.................
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
sessionmngr = new SessionManager(this);
//check the user login or not
if (sessionmngr.isLoggedIn()) {
Intent checkLoginIntnt = new Intent(this,ProjectFragActivity.class);
startActivity(checkLoginIntnt);
}
setContentView(R.layout.activity_login);
........
}
// onclick listener when click on login activity
public void LoginToBookingScape(View v) throws JSONException {
username = edtTxtUserName.getText().toString();
userpsw = edtTxtUserPsw.getText().toString();
if ((username.trim().length() > 0)&&(userpsw.trim().length() > 0)) {
JsonWebService jsonWebs = new JsonWebService();
jsonWebs.execute(loginUrl);
}else {
............
}
}
以下是在LoginActivity中扩展AsyncTask的Inner类 …
在我的启动画面中,我做了它,以便检测是否启用了wifi或3g.如果不是,则会出现一个对话框,提示用户退出并打开其中一个.如果它打开,则代码将继续.我的logcat中一直有一个关于我的活动有一个泄漏窗口的错误.我不知道如何解决这个问题.代码和logcat如下.有任何想法吗？
这是我的代码:
//create alert dialog for wifi and 3g
connectionDialog = new AlertDialog.Builder(SplashMain.this).create();
Log.d(TAG, "dialog created");
connectionDialog.setTitle("Wifi or 3G not detected. Please enable either Wifi or 3G");
connectionDialog.setButton("Exit", new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
finish();
}
});
wifiHandler = new Handler();
setContentView(R.layout.splashscreen); //Make the splash screen load first
Thread splashScreenTimer = new Thread(){ //create a timer for the splash screen
public void run(){ //create a run class
