How to display the Soft Keyboard from a Service?
(3 answers)
Closed 3 years ago.
In my application i should use Vertical Stepper and for this i added below library : VerticalStepperForm.
I should use this stepper into service and for this i write below codes.
But when use this codes into Service, when click on EditText not open soft keyboard (not show me any keyboard), but when use this codes into activity, it's not bug and show me keyboard.
But into service not show any keyboard!
My service codes:
public class FloatingLayoutService extends Service implements StepperFormListener {
private WindowManager windowManager;
private ConstraintLayout floatingLayout, floatingLay_root, floatingLay_main;
private IBinder binder = new ServiceBinder();
private LinearLayout floatingLay_headerLay;
private List<Step> steps = new ArrayList();
private List<Integer> intList = new ArrayList<>();
private List<TestStepsListResponse.Datum> testPlans = new ArrayList<>();
//Timer
private boolean running;
private int stepIndex = 1;
#Override
public int onStartCommand(Intent intent, int flags, int startId) {
windowManager = (WindowManager) getSystemService(WINDOW_SERVICE);
//Inflate the layout using LayoutInflater
LayoutInflater li = (LayoutInflater) getSystemService(LAYOUT_INFLATER_SERVICE);
floatingLayout = (ConstraintLayout) li.inflate(R.layout.service_floating_layout, null);
//Init view
initUi();
//Set layout params to display the controls over any screen.
final WindowManager.LayoutParams params = new WindowManager.LayoutParams(
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.MATCH_PARENT,
WindowManager.LayoutParams.TYPE_APPLICATION_OVERLAY,
WindowManager.LayoutParams.FLAG_NOT_FOCUSABLE,
PixelFormat.TRANSLUCENT);
// From API26, TYPE_PHONE deprecated. Use TYPE_APPLICATION_OVERLAY for O
if (Build.VERSION.SDK_INT < Build.VERSION_CODES.O)
params.type = WindowManager.LayoutParams.TYPE_PHONE;
//Initial position of the floating controls
params.gravity = Gravity.BOTTOM | Gravity.START;
params.x = 0;
params.y = 0;
//Add the controls view to windowManager
windowManager.addView(floatingLayout, params);
//Steps
testPlans = App.testPlansList;
for (int i = 0; i < testPlans.size(); i++) {
if (testPlans.get(i).getItemType().equals(ConstKeys.TEST_STEP_TEXT_RESPONSE)) {
StepDynamicEdt stepDynamicTxt = new StepDynamicEdt(testPlans.get(i).getTitle(), testPlans.get(i).getDesc());
// add to list
steps.add(stepDynamicTxt);
intList.add(i);
} else {
StepDynamicTxt stepDynamicEdt = new StepDynamicTxt(testPlans.get(i).getTitle(), testPlans.get(i).getDesc());
// add to list
steps.add(stepDynamicEdt);
}
}
floatingLay_stepper.setup(this, steps)
.allowNonLinearNavigation(false)
.displayCancelButtonInLastStep(false)
.displayBottomNavigation(false)
.confirmationStepTitle("OK")
.stepNextButtonText("Next")
.lastStepNextButtonText("Finish")
.includeConfirmationStep(false)
.init();
return START_STICKY;
}
StepDynamicEdt class codes:
public class StepDynamicEdt extends Step<String> {
private static final int MIN_CHARACTERS = 1;
private EditText editText;
private String errorMessage;
public StepDynamicEdt(String title) {
this(title, "");
}
public StepDynamicEdt(String title, String subtitle) {
super(title, subtitle);
}
#NonNull
#Override
protected View createStepContentLayout() {
//Create view programmatically
editText = new EditText(getContext());
editText.setHint("User name");
editText.setSingleLine(true);
editText.addTextChangedListener(new TextWatcher() {
#Override
public void beforeTextChanged(CharSequence s, int start, int count, int after) {
}
#Override
public void onTextChanged(CharSequence s, int start, int before, int count) {
markAsCompletedOrUncompleted(true);
}
#Override
public void afterTextChanged(Editable s) {
}
});
editText.setOnEditorActionListener(new TextView.OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
getFormView().goToNextStep(true);
return false;
}
});
errorMessage = "Insert 1 character";
return editText;
}
#Override
public String getStepData() {
Editable text = editText.getText();
if (text != null) {
return text.toString();
}
return "";
}
#Override
public String getStepDataAsHumanReadableString() {
String name = getStepData();
return name == null || name.isEmpty() ? "Empty" : name;
}
#Override
public void restoreStepData(String data) {
if (editText != null) {
editText.setText(data);
}
}
#Override
protected IsDataValid isStepDataValid(String stepData) {
if (stepData.length() < MIN_CHARACTERS) {
return new IsDataValid(false, errorMessage);
} else {
return new IsDataValid(true);
}
}
#Override
protected void onStepOpened(boolean animated) {
// No need to do anything here
}
#Override
protected void onStepClosed(boolean animated) {
// No need to do anything here
}
#Override
protected void onStepMarkedAsCompleted(boolean animated) {
// No need to do anything here
}
#Override
protected void onStepMarkedAsUncompleted(boolean animated) {
// No need to do anything here
}
}
Update : I added below code into StepDynamicEdt class, but again not open keyboard!
InputMethodManager imm = (InputMethodManager) getContext().getSystemService(
Context.INPUT_METHOD_SERVICE);
Objects.requireNonNull(imm).showSoftInput(editText, 0);
How can i fix it and open keyboard into service ?

Issue with RecyclerView data interchanges while scrolling

There is Scroll by loading RecyclerView(Lazy loading). When an item quantity is incremented by adding the plus button to say 10. after loading the next set of items while scrolling, The item quantity(10) is reset to 1 and 10 will be displayed for another item.
In the same sequence, if the unit is changed(by the spinner) to another unit the corresponding image will be loaded but after scrolling the unit and image will change back to initial unit.
When the image of an item is clicked, a dialog will show the details of the selected item . Sometimes the image in the dialog is correct but image of the RecyclerView is incorrect, will take time to load or will not load.
public class ArticleRecyclerViewAdapter extends RecyclerView.Adapter<RecyclerView.ViewHolder>

Plz someone suggest my the right way to do it. I realy need help.

Android: How should I pass a ListView between activities, when the Context object disallows Parcelable?

I'm creating an alarm clock application, and I'd like the homepage to have multiple Alarm objects shown, like the default Android clock application. To do this, I've been trying a ListView to create a button for each Alarm in an ArrayList of Alarms.
Debugging the crashes this caused, I've found that it can't implement Serializable or Parcelable due to the Context object within it, and thus I have no way to pass it from one activity to another. The ListView works fine when I create the alarms from the MainActivity itself, but when I use the CreateAlarmActivity that takes input from the user, the ListView won't pass through and it crashes.
I haven't found this precise problem on StackOverflow. This problem is close (Implementing Parcelable Class That Requires Context) but involves a database, which seems overkill for my needs.
If a ListView is even the best way to go about this, how should I pass the ListView between activities? If there's a better way, what would be a better implementation?
I apologise for the large amount of code. I'm not sure exactly what may prove relevant, so I've erred on the side of too much information rather than too little.
Code:
MainActivity.java:
public class MainActivity extends AppCompatActivity {
ListView alarmListView;
ArrayList<Alarm> alarmList = new ArrayList<Alarm>();
int[] testArray = {0, 0, 0, 0, 0, 0, 0};

How to Delete Item Without Deleting Position in Recycler View?

I really need your help. I've searched Google many days with many keywords, but I couldn't get it. So, I decided to ask to you.
So, here it is. Actually, I have one button in RecyclerView, but this button is repeated as much amount of data available, there are: Button with text "Baca 3x", "Baca 4x", and so on. I want, if I click button with text "Baca 3x" 3 times, it will change to "Baca 2x" >> "Baca 1x" >> remove item. Also if I click button with text "Baca 4x" 4 times, it will change to "Baca 3x" >> "Baca 2x" >> "Baca 1x" >> remove item.
But my problem is, I can't treat every button with different treatment, because every time the item has been deleted, position of data changes automatically. Because of this, I can't get specific button. For example: There is two button,
1. Button "Baca 3x" on position 0
2. Button "Baca 4x" on position 1
If button "Baca 3x" on position 0 has been deleted, so button "Baca 4x" changed it's position automatically to 0. The problem lays here.
Until now I just get every button based on their positions, which is a problem for me. Because of this I am thinking about How to Delete Item Without Deleting Position in Recycler View? Can you guys solve my problem? Should I use DiffUtil?And how to use it? Below the complete code I use:

UPDATE (FIX CODE) By: Krishna Sharma:
https://github.com/seadclark/RecyclerViewWithButtonClicks

Here is the fix. just update the ModelDoa constructor as below. I have verified myself and working as expected now. Also sent you pull request on github.
public ModelDoa(String name, String butong, int type) {
this.mName = name;
this.bName = butong;
this.mType = type;
String[] data = butong.split("\\s");
if (data.length > 0) {
String count = data[1].substring(0, data[1].length() - 1);
read10 = Integer.parseInt(count);
}
}

Instead of removing the item from your list AND updating the interface, have two methods. One of them (deleteItem) will only delete the item and the other (deleteItemAndUpdate) will delete the item and update the interface.
public void deleteItem(int position) {
mList.remove(position); // hapus list
}
public void deleteItemAndUpdate(int position) {
mList.remove(position); // hapus list
notifyItemRemoved(position); // hapus tampilan
}
In the future, you can decide whether you want to only remove the item from your list OR remove the item and update the UI.
EDIT 1:
You need to keep track of the amount of times that each item was clicked. We can call this value readCount. Every time that the item is clicked, we subtract 1 from this value. When this value reaches 0, we remove it from the list.
ModelDoa:
public class ModelDoa {
private int readCount = 10;
public int getReadCount() {
return this.readCount;
}
public void setReadCount(int readCount) {
this.readCount = readCount;
}
}
PagiViewHolder:
private View.OnClickListener bacaClickListener = new View.OnClickListener() {
#Override
public void onClick(View v) {
teksbaca = (Button) v.findViewById(R.id.buttonbaca);
ModelDoa modelDoa = mAdapter.getItem(getAdapterPosition());
if (modelDoa != null) {
modelDoa.setReadCount(modelDoa.getReadCount() - 1);
if (modelDoa.getReadCount() <= 0) {
myAdapter.deleteItem(getAdapterPosition());
}
teksbaca.setText("Baca " + modelDoa.getReadCount() + "x");
}
}
};
AdapterDoa:
public ModelDoa getItem(int position) {
if (position > -1 && position < getItemCount()) {
return this.mList.get(position);
} else {
return null;
}
}
EDIT 2:
The idea is to set the readCount variable when you instantiate the object. You do not have multiple variables that do the same thing. You just change the single readCount variable to be either 7 or 10 when you are creating it and use the same getItem method when retrieving the model (not variable!) itself.
ModelDoa:
public class ModelDoa {
private String name;
private String butong;
private int type;
private int readCount;
