#Override
public void onCreate() {
super.onCreate();
}
#Override
public void onNotificationPosted(StatusBarNotification sbn) {
otherActivity oth = new otherActivity();
oth.loc();

Log.i("Msg", "Notification Removed");
}
}
otherActivity
public class OtherActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_other);
}
public void loc() {
//code body
}
}

I want to lock add to WhatsApp and unlock it by watching video reward.
but this stickerdetails showed from listview from

so, how to implement video reward ads only in 1 specified item of the listview not all of them?
public class MainActivity extends AppCompatActivity implements RewardedVideoAdListener {
private RewardedVideoAd mRewardedVideoAd;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
MobileAds.initialize(this,"ca-app-pub111111111");
mRewardedVideoAd = MobileAds.getRewardedVideoAdInstance(this);

I have an AppCompatPreferenceActivity.java. But it shows an error in this
public class SettingsActivity extends AppCompatPreferenceActivity
It says it couldn't resolve 'AppCompatPreferenceActivity'.
And it seems like I am the only one with this problem. Any idea?
Error:(21, 39) error: cannot find symbol class AppCompatPreferenceActivity
AppCompatPreferenceActivity does not existing in google support libary,
you should create a class with same name and use this source:
public abstract class AppCompatPreferenceActivity extends PreferenceActivity {
private AppCompatDelegate mDelegate;
#Override
protected void onCreate(Bundle savedInstanceState) {
getDelegate().installViewFactory();
getDelegate().onCreate(savedInstanceState);
super.onCreate(savedInstanceState);
}
#Override
protected void onPostCreate(Bundle savedInstanceState) {
super.onPostCreate(savedInstanceState);
getDelegate().onPostCreate(savedInstanceState);
}
public ActionBar getSupportActionBar() {
return getDelegate().getSupportActionBar();
}
public void setSupportActionBar(#Nullable Toolbar toolbar) {
getDelegate().setSupportActionBar(toolbar);
}
#Override
public MenuInflater getMenuInflater() {
return getDelegate().getMenuInflater();
}
#Override
public void setContentView(#LayoutRes int layoutResID) {
getDelegate().setContentView(layoutResID);
}
#Override
public void setContentView(View view) {
getDelegate().setContentView(view);
}
#Override
public void setContentView(View view, ViewGroup.LayoutParams params) {
getDelegate().setContentView(view, params);
}
#Override
public void addContentView(View view, ViewGroup.LayoutParams params) {
getDelegate().addContentView(view, params);
}
#Override
protected void onPostResume() {
super.onPostResume();
getDelegate().onPostResume();
}
#Override
protected void onTitleChanged(CharSequence title, int color) {
super.onTitleChanged(title, color);
getDelegate().setTitle(title);
}
#Override
public void onConfigurationChanged(Configuration newConfig) {
super.onConfigurationChanged(newConfig);
getDelegate().onConfigurationChanged(newConfig);
}
#Override
protected void onStop() {
super.onStop();
getDelegate().onStop();
}
#Override
protected void onDestroy() {
super.onDestroy();
getDelegate().onDestroy();
}
public void invalidateOptionsMenu() {
getDelegate().invalidateOptionsMenu();
}
private AppCompatDelegate getDelegate() {
if (mDelegate == null) {
mDelegate = AppCompatDelegate.create(this, null);
}
return mDelegate;
}
}
community,
I'm programming in android and i have 2 classes, the mainactivity and a other class with a SpeechRecognizer(a listener).
I want to give the activity a sign that the listener is done with listining, how can i do that?
Should i extend the SpeechRecognizer-class with the mainActivity-class and then call a method from the mainActivity-class in the SpeechRecognizer-class?
Here is a simplified version of my code to understand my problem:
thirst class:
puplic class mainActivity{
onCreate(){
speech.startListening();
}
}
second class:
pulbic class speech implements Recognizer{
startListening(){
//start the listener
}
#Override
onResult(){
//hear i get my string after a random various amount of time
//(when the recognizer is done with hearing my stuff)
//at this point i want to let the other class know, that im done here
}
}
I hope you understand my problem, i think its an easy one, but i dont know a solution..
Greetings
Just call setRecognitionListener on your MainActivity.
public class MainActivity extends Activity {
SpeechRecognizer speech;
public void onCreate(){
super.onCreate();
speech.startListening();
recognizer.setRecognitionListener(new RecognitionListener() {
#Override
public void onReadyForSpeech(Bundle bundle) {
}
#Override
public void onBeginningOfSpeech() {
}
#Override
public void onRmsChanged(float v) {
}
#Override
public void onBufferReceived(byte[] bytes) {
}
#Override
public void onEndOfSpeech() {
}
#Override
public void onError(int i) {
}
#Override
public void onResults(Bundle bundle) {
}
#Override
public void onPartialResults(Bundle bundle) {
}
#Override
public void onEvent(int i, Bundle bundle) {
}
});
}
}
How do I know the state of the ToggleButton from another activity?
i have class
public class MainScreen extends Activity{
protected ToggleButton tgbutton;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainscreen);
tgbutton = (ToggleButton)findViewById(R.id.advice);
SharedPreferences sharedPreferences = PreferenceManager
.getDefaultSharedPreferences(getApplicationContext());
tgbutton.setChecked(sharedPreferences.getBoolean("toggleButton", false));
}
public void oneClick(View v) {
if(tgbutton.isChecked() == false) { playSound(mSound); }
else { pauseSound(mSound); }
}
}
and
public class SmallprintA extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.smallprint_a);
OnClickListener SendOnClickListener = new OnClickListener() {
#Override
public void onClick(View v) {
if(tgbutton.isChecked() == true){ playSound(mEmpty); }
else { playSound(mEmpty); }
}
};
}
I need in the class SmallprintA determine the state of the ToggleButton tgbutton. This is possible without class inheritance?
I did tgbutton is static
public class MainScreen extends Activity{
protected static ToggleButton tgbutton; // STATIC
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.mainscreen);
tgbutton = (ToggleButton)findViewById(R.id.advice);
}
public void oneClick(View v) {
if(tgbutton.isChecked() == false) { playSound(mSound); }
else { pauseSound(mSound); }
}
}
and
public class SmallprintA extends Activity {
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.smallprint_a);
OnClickListener SendOnClickListener = new OnClickListener() {
#Override
public void onClick(View v) {
if(MainScreen.tgbutton.isChecked() == true){ playSound(mEmpty); }
else { playSound(mEmpty); }
}
};
}
I'm doing a unit test of an activity. My activity has a button that calls a simple method (no activities, services or anything else).
java.lang.NullPointerException at
com.android.my.test.MyActivityTest.testPerformClick(MyActivity.java:41) at
java.lang.reflect.Method.invokeNative(Native Method) at
android.test.InstrumentationTestCase.runMethod(InstrumentationTestCase.java:205)
at
android.test.InstrumentationTestCase.runTest(InstrumentationTestCase.java:195)
at
android.test.ActivityInstrumentationTestCase2.runTest(ActivityInstrumentationTestCase2.java:175)
at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:169)
at android.test.AndroidTestRunner.runTest(AndroidTestRunner.java:154)
at
android.test.InstrumentationTestRunner.onStart(InstrumentationTestRunner.java:430)
at
android.app.Instrumentation$InstrumentationThread.run(Instrumentation.java:1447)
My test is this:
public class MyActivityTest extends ActivityInstrumentationTestCase2<MyActivity> {
MyActivity a;
public MyActivityTest() {
super("com.android.my", MyActivity.class);
}
#Override
public void setUp() throws Exception {
super.setUp();
a = this.getActivity();
}
#Override
public void tearDown() throws Exception {
super.tearDown();
}
public void testPerformClick() {
a.getButton().performClick();
}
}
And my activity is this.
public class MyActivity extends Activity implements OnClickListener {
private Button b;
#Override
public void onCreate(Bundle savedInstanceState) {
button = new Button();
button.setOnClickListener(this);
}
#Override
public void onClick(View arg0) {
method();
}
private void method() {
// [...]
}
public void getButton() {
return button();
}
}
My guess is that you need to change MyActivity to this. Your test is getting a NULL for the method getButton()
public class MyActivity extends Activity implements OnClickListener
{
private Button b;
#Override
public void onCreate(Bundle savedInstanceState)
{
b=new Button();
b.setOnClickListener(this);
}
#Override
public void onClick(View arg0)
{
method();
}
private void method()
{
...
}
public Button getButton()
{
return b;
}
}
