【无法添加窗口 - 令牌android.os.BinderProxy@42824无效; 你的活动在运行吗（）】我有一个带有pendingIntent的短信发送者，一旦短信发送它就打开一个对话框。这是SMS发件人的代码

public final void sendSmsByManager(final String code) { progressDialog = new ProgressDialog(Registration.this); progressDialog.setTitle("Please wait"); progressDialog.setMessage("Sending SMS Verification Code..."); progressDialog.setCancelable(false); progressDialog.setCanceledOnTouchOutside(false); progressDialog.show(); String sent = "SMS_SENT"; PendingIntent sentPI = PendingIntent.getBroadcast(Registration.this,2, new Intent(sent), 0); Registration.this.registerReceiver(new BroadcastReceiver() { @Override public void onReceive(Context arg0, Intent arg1) {switch (getResultCode()){case Activity.RESULT_OK:// Toast.makeText(getBaseContext(), "SMS sent",// Toast.LENGTH_SHORT).show(); progressDialog.dismiss(); dialog_confirm(code,Registration.this); // saveRegistration(); break; case SmsManager.RESULT_ERROR_GENERIC_FAILURE: progressDialog.dismiss(); Toast.makeText(getApplicationContext(), "Generic failure",Toast.LENGTH_SHORT).show(); // Toast.makeText(getApplicationContext(), "code" + code,// Toast.LENGTH_SHORT).show(); status = "Generic failure"; break; case SmsManager.RESULT_ERROR_NO_SERVICE: progressDialog.dismiss(); Toast.makeText( myContext, "No service. Check mobile network connection." + "" + "",Toast.LENGTH_SHORT).show(); status = "No service"; break; case SmsManager.RESULT_ERROR_NULL_PDU: progressDialog.dismiss(); Toast.makeText(getApplicationContext(), "Null PDU",Toast.LENGTH_SHORT).show(); status = "Null PDU"; break; case SmsManager.RESULT_ERROR_RADIO_OFF: progressDialog.dismiss(); Toast.makeText(getApplicationContext(), "Radio off",Toast.LENGTH_SHORT).show(); status = "Radio off"; break; }}}, new IntentFilter(sent)); SmsManager sms = SmsManager.getDefault(); sms.sendTextMessage(txt_mobileno.getText().toString(), null, code, sentPI, null); }

我从Activity.RESULT_OK调用对话框

public void dialog_confirm(final String SMSCode,Context context) {dialog = new Dialog(context); dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE); dialog.getWindow().setBackgroundDrawable( new ColorDrawable(android.graphics.Color.TRANSPARENT)); dialog.setContentView(R.layout.dialog_confirm); final EditText txt_code = (EditText) dialog.findViewById(R.id.txt_code); Button btn_add = (Button) dialog.findViewById(R.id.btn_confirm); Button btn_cancel = (Button) dialog.findViewById(R.id.btn_cancel); btn_add.setOnClickListener(new OnClickListener() {@Override public void onClick(View v) { // TODO Auto-generated method stub String code = txt_code.getText().toString(); if (code.equals(SMSCode)) { match = true; // save if (Constants.ID != 0) {updateRegistration(); } else {saveRegistration(); }dialog.dismiss(); } else { DialogUtil.createErrorDialog(Registration.this, "Registration Error", "SMS verification code does not match!").show(); }}}); btn_cancel.setOnClickListener(new OnClickListener() {@Override public void onClick(View v) { // TODO Auto-generated method stub dialog.dismiss(); } }); dialog.setCancelable(false); dialog.show(); }

dialog.show上有错误点，这是截图。

答案问题可能是上下文在对话框显示时被破坏了。这可以像这样避免：

if(!((Activity) context).isFinishing()) { //show dialog }

另一答案如果在定义活动时在AndroidManifest.xml中添加了以下行

android:noHistory="true"

您在AndroidManifest.xml文件中定义的活动应如下所示

< activity android:name=".Signup" android:label="@string/title_activity_signup" android:parentActivityName=".LoginSignup" android:screenOrientation="portrait" android:theme="@style/AppTheme.NoActionBar"> < meta-data android:name="android.support.PARENT_ACTIVITY" android:value="https://www.songbingjia.com/android/com.yourpackage.LoginSignup" />
