Probably da error in the code is that you never defined an id "add" - you have #+id/TextView01 in the xml "page" (you mean file - and you must tell us which file) but no #+id/add

I have an app with PopupWindow containing WebView that opens Facebook's page, any context menu like: the Autocomplete on text fields in the WebView or even the Long Press that should display options for the user to copy/paste/cut crashes the app right away with the follow error:

Notice: my understanding of the problem is that the context menu/window are shown actually in the scope of the app itself not inside the WebView using another PopWindow (Auto generated by the Core WebView Class) this class references the context incorrectly.
My Code is as follows:

As commented above in my answer you can use Custom dialog for your requirement.. i have created a sample PopupDialog.. please check and let me know..if it solve your purpose.. Autocomplete and ContextMenus will work as expected..
MyActivity.java
package com.example.testapp;

popupDialog.setContentView(R.layout.popup);
WebView popupWebview = (WebView) popupDialog.findViewById(R.id.webviewActionView);
popupWebview.setWebChromeClient(new WebChromeClient());
popupWebview.setWebViewClient(new WebViewClient());
popupWebview.loadUrl("http://m.facebook.com");
Button btnDismiss = (Button) popupDialog
.findViewById(R.id.dismiss);
btnDismiss.setOnClickListener(new Button.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
popupDialog.dismiss();
}
});
// popupDialog.showAtLocation(50,50);
popupDialog.showAsDropDown(findViewById(R.id.openpopup));
}
});
}
}

}
public void showAsDropDown(View view)
{

yes i think you should use your activity name in place of "getBaseContext()". i am just created one demo with your code. its working fine in my pc. and when you are getting this exception?
Nothing wrong in your code..seems to be Android 4.1+ specific issue..
Webview is also using PopupWindow for showing Paste context menu in input box..Nested popupwindows through webview is causing WindowManager crash, while adding new view to it.
I have tried Custom Dialog(in place of Popupwindow) with embedded Webview, Paste context menu is coming fine in Android 4.1+..
If you are not so specific about this paste context menu you can disable it for particular android version using below code..i have tried it.. it will stop app from being crash..
popupWebView.setOnLongClickListener(new OnLongClickListener() {
#Override
public boolean onLongClick(View v) {
if (Build.VERSION.SDK_INT >= 16)
return true;
return false;
}
});
Also you can look at Webview HitTestResult class for displaying some custom made Context menus, according to your needs..
users have an activity with an edittext and a button.
in the edittext they have to insert their login ID. and press go to display a other activity with webview loading the right site.
an example. this is the link i want users to visit . www.example.com/time/id=1/type=student
if sombody enters a 2 in the edittext it wil open the times for student id 2 and so on.
this is what i have.
LOGIN
package com.beter;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.app.Activity;
import android.content.Intent;
public class LoginActivity extends Activity {
Button go_btn;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.login);
go_btn = (Button) findViewById(R.id.go_btn);
go_btn.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
Intent myIntent = new Intent(LoginActivity.this, WebActivity.class);
LoginActivity.this.startActivity(myIntent);
}
});
}
and the layout
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent" >
<EditText
android:id="#+id/idfield"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:ems="10"
android:hint="#string/id"
android:inputType="number" >
<requestFocus />
</EditText>
<Button
android:id="#+id/go_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentRight="true"
android:layout_alignParentTop="true"
android:layout_toRightOf="#+id/idfield"
android:text="#string/login" />
The Webview Activity
package com.beter;
import android.app.Activity;
import android.os.Bundle;
import android.webkit.WebView;
public class WebActivity extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.webview);
WebView webview = new WebView(this);
setContentView(webview);
webview.loadUrl("http://roosters.gepro-osi.nl/roosters/rooster.php?wijzigingen=1&leerling=116277&type=Leerlingrooster&afdeling=12-13_OVERIG&school=905");
}
}
and again the layout
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<WebView
android:id="#+id/webView1"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</LinearLayout>
How do i make the user input. display the good webview. ?
First of all get a reference to your edittext in your Login Activity as
go_btn = (Button) findViewById(R.id.go_btn);
ed_txt = (EditText)findViewById(R.id.youredittextid);
The change your onClick to
public void onClick(View v) {
Intent myIntent = new Intent(LoginActivity.this, WebActivity.class);
myIntent.putExtra("id", ed_txt.getText());
LoginActivity.this.startActivity(myIntent);
}
Then retrive this id in your WebActivity onCreate as
String id = getIntent().getExtras().getString("id");
Then your url will be
String myURL = "www.example.com/time/id="+id+"/type=student";
i try make spinner and button with clickHandler
this is my nyoba.java
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.AdapterView;

public class nyoba extends Activity {
String[] nama_hari = {"Senin", "Selasa", "Rabu","Kamis","Jum'at","Sabtu","Minggu"};
/** Called when the activity is first created. */
Spinner spinner1;
Button btnSubmit;
TextView textView1;
String tes;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
btnSubmit = (Button)findViewById(R.id.btnSubmit);
textView1 = (TextView)findViewById(R.id.textView1);
spinner1 = (Spinner)findViewById(R.id.spinner1);
ArrayAdapter<String> aa = new ArrayAdapter<String>(this,android.R.layout.simple_spinner_item, nama_hari);
aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
spinner1.setAdapter(aa);
}
public void onItemSelected(AdapterView<?> arg0, View arg1,
int arg2, long arg3) {
tes = nama_hari[arg2];
}
public void clickHandler(View view){
switch (view.getId()){
case R.id.btnSubmit:
textView1.setText(tes);
break;
}
}
}
and this is my main.xml file
<?xml version="1.0" encoding="utf-8"?>

android:layout_height="fill_parent"

but when i run it to emulator,and i choose 1 option in spinner and click the button , the TextView doesn't show up the word from spinner which i choose
(for example, i choose "senin" at spinner, and click the button, but the text "senin" doesn't appear in the TextView )
i check DDMS and there are no error.....
is the code wrong?
can you help me please which one is wrong?
Thank anyway....
I think you don't set the selection listener on your spinner.
But actually you can just retrieve the spinner's selected position with getSelectedItemPosition in the click handler of your button:
Try this:
public void clickHandler(View view) {
switch (view.getId()) {
case R.id.btnSubmit:
textView1.setText(nama_hari[spinner1.getSelectedItemPosition()]);
break;
}
}
about text in the message there is not problem. I can't change (personalize) color, font, style of Title of alertdialog?
What's the way?
thanks!
About font size you can use this:
SpannableStringBuilder ssBuilser = new SpannableStringBuilder("Sample");
StyleSpan span = new StyleSpan(Typeface.ITALIC);
ScaleXSpan span1 = new ScaleXSpan(1);
ssBuilser.setSpan(span, 0, 5, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
ssBuilser.setSpan(span1, 0, 5, Spanned.SPAN_INCLUSIVE_INCLUSIVE);
AlertDialog.Builder builder = new AlertDialog.Builder(MainActivity.this);
builder.setTitle(ssBuilser);
builder.show();
or
AlertDialog dialog = new AlertDialog.Builder(this).setMessage("Hello world").show();
TextView textView = (TextView) dialog.findViewById(android.R.id.message);
textView.setTextSize(40);
Check out this link: Creating dialogs
This should help.
Or this Alert Dialog Builder
There is another way to set a new custom view to a dialog title. We can define every custom view such as TextView and add it some custom properties and set it to the dialog title:
AlertDialog.Builder builder = new AlertDialog.Builder(OrderItemsActivity.this);
TextView title_of_dialog = new TextView(getApplicationContext());
title_of_dialog.setHeight(50);
title_of_dialog.setBackgroundColor(Color.RED);
title_of_dialog.setText("Custom title");
title_of_dialog.setTextSize(TypedValue.COMPLEX_UNIT_SP, 15);
title_of_dialog.setTextColor(Color.WHITE);
title_of_dialog.setGravity(Gravity.CENTER);
builder.setCustomTitle(title_of_dialog);
builder.create().show();
Here, I define a dynamic TextView and set some properties to it. Finally, I set it to dialog title using setCustomTitle().
Here is an full example how i would do it. See the last line of code.
AlertDialog.Builder alertDialogBuilder = new AlertDialog.Builder(cntx);
alertDialogBuilder
.setMessage(Html.fromHtml(cntx.getString(R.string.UltimateDemoText)))
.setCancelable(false)
.setPositiveButton(cntx.getString(R.string.Ok), new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog,int id) {
dialog.cancel();
}
});
AlertDialog alertDialog = alertDialogBuilder.create();
alertDialog.show();
((TextView)alertDialog.findViewById(android.R.id.title)).setTextSize(TypedValue.COMPLEX_UNIT_SP, 9);
Let's take example of this customised Dialog. Below are the files used to make it :
res/layout/dialog.xml :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"> <EditText
android:id="#+id/et_pc_forDialog"

android:singleLine="true"

<requestFocus />

<TextView
android:id="#+id/tv_pc_dialogTitle"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"

MainActivity.java :
package com.bhavit.stackoverflow;
import android.os.Bundle;
import android.app.Activity;
import android.app.Dialog;
import android.app.Dialog;
import android.graphics.Typeface;
import android.view.Menu;

public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
Button openDialog = (Button) findViewById(R.id.button1);
openDialog.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Dialog dialog = new Dialog(MainActivity.this); // here write the name of your activity in place of "YourActivity"
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.setContentView(R.layout.dialog);
TextView tv = (TextView)dialog.findViewById(R.id.tv_pc_dialogTitle);
Typeface tf = Typeface.createFromAsset(getAssets(), "fonts/GOTHIC.TTF"); // here GOTHIC.TTF is the font-file I have pasted in the asset/fonts folder in my project
tv.setTypeface(tf); // Set the typeface like this
Button bt = (Button) dialog.findViewById(R.id.bt_pc_goButton);
bt.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// Write here, what do you want to do on button click
}
});
dialog.show();
}
});
}
}
This is how you can make a customised dialog, and customise the components of that dialog. Here I have set a custom font to the title of the Dialog.
I have this code:
package com.problemio;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
public class ProblemioActivity extends Activity
{
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button addProblemButton = (Button)findViewById(R.id.add_problem_button);
Button browseProblemsButton = (Button)findViewById(R.id.browse_problems_button);
Button searchProblemsButton = (Button)findViewById(R.id.search_problems_button);
Button myProblemsButton = (Button)findViewById(R.id.my_problems_button);
addProblemButton.setOnClickListener(new Button.OnClickListener()
{
public void onClick(View v) {
Intent myIntent = new Intent(ProblemioActivity.this, AddProblemActivity.class);
ProblemioActivity.this.startActivity(myIntent);
}
});
}
}
It compiles fine and displays the addProblemButton button, but when that button is clicked, the system gives a runtime exception.
Here is the AddProblemActivity class:
package com.problemio;
import android.app.Activity;
import android.content.Intent;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.TextView;
public class AddProblemActivity extends Activity
{
/** Called when the activity is first created. */
#Override
public void onCreate(Bundle savedInstanceState)
{
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
//TextView text = (TextView) dialog.findViewById(R.id.addProblemText);
//text.setText(R.string.addProblemText);
TextView tv = new TextView(this);
tv.setText("Please Add a Problem");
setContentView(tv);
}
}
and here is the layout main.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="First, add the problem you want to solve!"
/>
<TextView
android:id="#+id/add_problem_text"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Add a Problem You Want To See Solved"
/>
<Button
android:id="#+id/add_problem_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Add a Problem"
/>
<Button
android:id="#+id/browse_problems_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Browse Problems"
/>
<Button
android:id="#+id/search_problems_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="Search Problems"
/>
<Button
android:id="#+id/my_problems_button"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="View My Problems"
/>
</LinearLayout>
any idea what might be going wrong? By the way, I can't seem to locate the stack trace of the exception. Where should I look for that in Eclipse? All it currently shows me is AndroidRuntimeException - dalvik.system.NativeStart.main
Thanks!!
The only problem I can think of is that your Activity "AddProblemActivity" is not register in the manifest.
See the logs under LogCat...you will find it in Window >Show View >Android > LogCat
