I have activity as a dialogue, all the shows I like. But I have a problem with a frame around them. Just like here.
My Activity:
public class AlarmAlert extends Activity implements Alarms.AlarmSettings {
#Override
protected void onCreate(Bundle icicle) {
super.onCreate(icicle);
AlarmAlertWakeLock.acquire(this);
/*
* FIXME Intentionally verbose: always log this until we've fully
* debugged the app failing to start up
*/
Log.v("AlarmAlert.onCreate()");
DigitalClock dc = (DigitalClock) findViewById(R.id.digitalClock1);
mKeyguardManager = (KeyguardManager) getSystemService(Context.KEYGUARD_SERVICE);
Intent i = getIntent();
mAlarmId = i.getIntExtra(Alarms.ID, -1);
Alarms.getAlarm(getContentResolver(), this, mAlarmId);
mKlaxon = new AlarmKlaxon();
mKlaxon.postPlay(this, mAlarmId);
/* Set the title from the passed in label */
setTitleFromIntent(i);
/*
* allow next alarm to trigger while this activity is active
*/
Alarms.disableSnoozeAlert(AlarmAlert.this);
Alarms.disableAlert(AlarmAlert.this, mAlarmId);
Alarms.setNextAlert(this);
mKlaxon.setKillerCallback(new AlarmKlaxon.KillerCallback() {
public void onKilled() {
if (Log.LOGV)
Log.v("onKilled()");
updateSilencedText();
/* don't allow snooze */
mSnoozeButton.setEnabled(false);
dismiss();
mState = KILLED;
}
});
updateLayout();
SharedPreferences settings = getSharedPreferences(
AlarmClock.PREFERENCES, 0);
if (settings.getBoolean(AlarmClock.PREF_SHAKE_SNOOZE, true)) {
mShakeListener = new ShakeListener(this);
mShakeListener
.setOnShakeListener(new ShakeListener.OnShakeListener() {
public void onShake() {
snooze();
if (mCaptchaSnooze == 0)
finish();
}
});
}
}
private void setTitleFromIntent(Intent i) {
mLabel = i.getStringExtra(Alarms.LABEL);
if (mLabel == null || mLabel.length() == 0) {
mLabel = getString(R.string.default_label);
}
setTitle(mLabel);
}
private void updateSilencedText() {
TextView silenced = (TextView) findViewById(R.id.silencedText);
silenced.setText(getString(R.string.alarm_alert_alert_silenced,
mDuration / 1000 * 60));
silenced.setVisibility(View.VISIBLE);
}
private void updateLayout() {
setContentView(R.layout.alarm_alert);

How do I remove the border.
dialog.getWindow().setBackgroundDrawableResource(android.R.color.transparent);
Dialog
You have two options. You can set the theme of your Activity to
Theme_Translucent_NoTitleBar
Or you have to create a new theme and load it with a custom nine patch as specified here

I found some code to press home button from code
Intent startMain = new Intent(Intent.ACTION_MAIN);
startMain.addCategory(Intent.CATEGORY_HOME);
startMain.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
startActivity(startMain);
and This one :
moveTaskToBack(true);
I have a activity that is in single task
And a alertDialog with a button then you click on the button one of those code run and go to home
so when you go to app again the alert dismissed before
I want to relaunch the app without dismissing alertDialog
What can i do?
thanks
AlertDialog default button will dissmis dialog .
you should create custom dialog with custom view
public class CustomDialog extends AlertDialog(){
TextView mTitleView,mDescriptionView;
Button mYesButton,mNoButton,mCancelButton;
boolean isYesButtonVisible = true;
boolean isNoButtonVisible = true;
boolean isCancelButtonVisible = true;
public CustomDialog(Context context){
super(context);
}
public void setYesButtonVisible(boolean isVisible){
isYesButtonVisible = isVisible
}
public void setNoButtonVisible(boolean isVisible){
isNoButtonVisible = isVisible
}
public void setCancelButtonVisible(boolean isVisible){
isCancelButtonVisible = isVisible
}
#override
public void show(){
super.show();
setContentView(R.layout.dialog_custom);
mTitleView = findViewById(R.id.text_title);
mDescriptionView = findViewById(R.id.text_description);
mYesButton = findViewById(R.id.btn_yes);
mNoButton = findViewById(R.id.btn_no);
mCancelButton = findViewById(R.id.btn_cancel);
isYesButtonVisible ? mYesButton.setVisibility(View.VISIBLE) : mYesButton.setVisibility(View.GONE);
isNoButtonVisible ? mNoButton.setVisibility(View.VISIBLE) : mNoButton.setVisibility(View.GONE);
isCancelButtonVisible ? mCancelButton.setVisibility(View.VISIBLE) : mCancleButton.setVisibility(View.GONE);
}
//must be called after dialog is showing else you will get NullPointerException
public void setOnYesClickListener(View.OnClickListener listener){
mYesButton.setonClickListener(listener);
}
public void setOnNoClickListener(View.OnClickListener listener){
mNoButton.setonClickListener(listener);
}
public void setOnCancelClickListener(View.OnClickListener listener){
mCancelButton.setonClickListener(listener);
}
}
and layout dialog_custom can be designed by yourself too but this is my layout file for custom dialog
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"

While creating AlertDialog with Builder you can set setCancelable(false);.
This question already has answers here:
What is a NullPointerException, and how do I fix it?

Closed 6 years ago.
When i click my button in my activity, it will stop and show an error like this :
Caused by: java.lang.NullPointerException: Attempt to invoke virtual method 'void android.widget.Button.setOnClickListener(android.view.View$OnClickListener)' on a null object reference
In my activity, i put button.setOnclickListener in onResponse() method from Response.Listener. I do this because i want to get the data from JSONObject and use that data when i click my button.
Sorry, I'm not too fluent in English :)
My activity code:
public class MenuDaftarNilai2 extends AppCompatActivity {
TextView tvMatkulDN, tvKlpDN, tvMhsDN;
Button bUasDN;
#Override

super.onCreate(savedInstanceState);
setContentView(R.layout.activity_menu_daftar_nilai2);
tvMatkulDN = (TextView) findViewById(R.id.tvMatkulDN) ;
tvKlpDN = (TextView) findViewById(R.id.tvKlpDN) ;
tvMhsDN = (TextView) findViewById(R.id.tvMhsDN) ;
bUasDN = (Button) findViewById(R.id.bUasDN) ;
Intent intent = getIntent();
final String nama_matkul = intent.getStringExtra("nama_matkul");
final String nama_klp = intent.getStringExtra("nama_klp");
final String nama_mhs = intent.getStringExtra("nama_mhs");
tvMatkulDN.setText(nama_matkul);
tvKlpDN.setText(nama_klp);
tvMhsDN.setText(nama_mhs);
Response.Listener responseListener1 = new Response.Listener<String>() {
#Override
public void onResponse(String response) {
try {
JSONObject jsonResponse = new JSONObject(response);
final String nilai_uas = jsonResponse.getString("nilai_uas");
final String id_uas = jsonResponse.getString("id_uas");
bUasDN.setText("Nilai Uas : " + nilai_uas);
bUasDN.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Intent intent = new Intent(MenuDaftarNilai2.this, EditUas.class);
intent.putExtra("nilai_uas", nilai_uas);
intent.putExtra("nama_matkul", nama_matkul);
intent.putExtra("nama_klp", nama_klp);
intent.putExtra("nama_mhs", nama_mhs);
intent.putExtra("id_uas", id_uas);
MenuDaftarNilai2.this.startActivity(intent);
finish();
}
});
}catch (JSONException e) {
e.printStackTrace();
}
}
};
ResponUas resUas = new ResponUas(nama_klp,nama_mhs, responseListener1);
RequestQueue queue1 = Volley.newRequestQueue(MenuDaftarNilai2.this);
queue1.add(resUas);

I just do my project but when I test my app I found that then I touch the screen by using more than one fingers my app may start two or three different activities.
The activities all go to the back stack. Is this a bug in Android framework? But I can't reappear this condition, it just happened.
So, have you guys ever have this problem? Please come and discuss with me. If you do; Thanks.
Supply:
And here is My xml file , when I click the different RelativeLayout at the same time , it happened.
I tried this afternoon , but this condition is not appear anymore. Now I am confusing.

You need to define the launch mode. There are at least two ways of solving this by either using the manifest file (hint: singleTop) or by using Intent flags (hint: FLAG_ACTIVITY_SINGLE_TOP).
Good luck!
Simpliest approach would be disable control that starts your Activity (button for example) after 1 click, and enable it later with some condition or action. Try it.
You can use this approach.......
((Button)findViewById(R.id.someButton)).setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
((Button)findViewById(R.id.someButton)).setEnabled(false);
}
});
Happy coding
Im having some issues, i have two Groups of Radiobuttons in my XML which has handling in an activity. It just crashes with nullpoint exception on line 48:
int languangeId = languageGroup.getCheckedRadioButtonId();
I have set a "default" checked button in the XML to one of the buttons in the buttongroup,
So why doesnt it get an valid value?:(
public class FirstTimeSelectMenu extends Activity{
private RadioGroup languageGroup;
private RadioGroup storageGroup;
private Button okButton;
private String getStorage;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.first_time_run);
languageGroup = (RadioGroup)this.findViewById(R.id.languageGroup);
storageGroup = (RadioGroup)this.findViewById(R.id.storageGroup);
okButton = (Button)findViewById(R.id.okBtn);
okButton.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
int languangeId = languageGroup.getCheckedRadioButtonId();
int storageId = storageGroup.getCheckedRadioButtonId();
RadioButton languageb = (RadioButton)findViewById(languangeId);
RadioButton storageb = (RadioButton)findViewById(storageId);
if(languageb.equals("Norwegian")){
//Need to fix this!
}
if(languageb.equals("English")){
//Need to fix this!
}
if(storageb.equals("SD Card")){
String sdStoragePath = Environment.getExternalStorageDirectory().toString() + "/PictureTalk/";
FileInteraction fi = new FileInteraction();
fi.firstTimeFillPath(getResources(), "PictureTalk/Food", sdStoragePath +"PictureTalk/Food");
fi.firstTimeFillPath(getResources(), "PrivatePictures", Environment.getExternalStorageDirectory().toString() +"PrivatePictures");
Intent intent = new Intent(getApplicationContext(),MainMenuActivity.class);
intent.putExtra("dataStorePath",sdStoragePath);
startActivity(intent);
}
}
});
}}

To start off with, what element is assigned the id "#+id/languageGroup" since it doesn't appear to be declared in your XML
I am trying to allow the user to put a ring on the circle on the screen and then press the larger button so that the circle goes to the next ring size.
Everything work fines when no ring is on the screen.
However when a ring it on the screen no other touches are called and the buttons and the seekbar does not work.
I'm new in android and i haven't came across this requirement before. Is there a way I can allow multi-touch gestures on the activity or a way to ignore touches on that specific layout?

There is a way to ignore touches in particular layout,for that you should add
android:splitMotionEvents="false"
in your layout . You can refer answers from thie following link
