How to hide widget when keyboard pops?

How to hide widget when keyboard pops? - android

I have two ViewPager on the same view with weight= 70/30 . The problem is when the keyboard pops, my both view keep the same weight and do not display my EditText.

I think my last solution is to make disappear my picker at the top when my keyboard pops. How can I do this?

Hope this help you :
public class YourActivity extends BaseActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.your_activity);
attachKeyboardListeners();
}
#Override
protected void onShowKeyboard(int keyboardHeight) {
// when keyboard is shown
yourWidget.setVisibility(View.GONE);
}
#Override
protected void onHideKeyboard() {
// when keyboard is hidden
yourWidget.setVisibility(View.VISIBLE);
}
}

Try to use ScrollView in parent view, for example-
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:app="http://schemas.android.com/apk/res-auto"
xmlns:fab="http://schemas.android.com/apk/res-auto"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:focusableInTouchMode="true">
<ScrollView
android:id="#+id/scroll_view_parent"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_alignParentLeft="true"
android:layout_alignParentStart="true"
android:layout_alignParentTop="true"
android:fillViewport="true"
android:scrollbars="none">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
..................................
type your code here
</LinearLayout>
<LinearLayout
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:background="#color/colorWhite"
android:orientation="vertical">
..................................
type your code here
</LinearLayout>
</LinearLayout>
</ScrollView>
</RelativeLayout>

You can set listeners when keyboard is opened and closed.
// ContentView is the root view of the layout of this activity/fragment
contentView.getViewTreeObserver().addOnGlobalLayoutListener(
new ViewTreeObserver.OnGlobalLayoutListener() {
#Override
public void onGlobalLayout() {
Rect r = new Rect();
contentView.getWindowVisibleDisplayFrame(r);
int screenHeight = contentView.getRootView().getHeight();
// r.bottom is the position above soft keypad or device button.
// if keypad is shown, the r.bottom is smaller than that before.
int keypadHeight = screenHeight - r.bottom;
Log.d(TAG, "keypadHeight = " + keypadHeight);
if (keypadHeight > screenHeight * 0.15) { // 0.15 ratio is perhaps enough to determine keypad height.
// keyboard is opened
} else {
// keyboard is closed
}
}
});

Items are not scrolling.
how to solve this. please help.
thanks in advance.

Then you need to change itemView's xml file ,
android:layout_height="match_parent"
instead of like ,
android:layout_height="wrap_content"

Simple change in spirometer_item.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
....Your design code
</LinearLayout>

I was having problem with the same from such a long time. Then I found a solution that worked for me.
Add a ListViewHelper java class. Here below is code for ListViewHelper.java
package com.molescope;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ListAdapter;
import android.widget.ListView;
public class ListViewHelper {
public static void getListViewSize(ListView listView){
ListAdapter adapter = listView.getAdapter();
if(adapter!=null){
int totalHeight = 0;
//setting list adapter in loop tp get final size
for (int i=0; i<adapter.getCount(); i++){
View listItem = adapter.getView(i, null, listView);
listItem.measure(0,0);
totalHeight += listItem.getMeasuredHeight();
}
//setting listview items in adapter
ViewGroup.LayoutParams params = listView.getLayoutParams();
params.height = totalHeight + (listView.getDividerHeight() *
(adapter.getCount()-1));
listView.setLayoutParams(params);
}else{
return;
}
}
}
And after adding this java file, in your code wherever you are setting adapter to listview, right after that line add the code below:
ListView myList=(ListView) findViewById(R.id.listView);
myList.setAdapter(new ArrayAdapter<String>.
(this,android.R.layout.simple_list_item_1, listview_array));
ListViewHelper.getListViewSize(myList);

Reverse layouts inside RelativeLayout programmatically

I have one relativeLayout and three view's inside RelativeLayout. There views are place on each other.
<RelativeLayout
android:id="#+id/includelayoutgroup"
android:layout_width="match_parent"
android:layout_height="match_parent">
<View xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/transparentColorView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:clickable="true"
android:visibility="visible" />
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/keyboard_main_layout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="vertical"
android:visibility="visible">
<include
layout="#layout/transfer_keyboard_fragment"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/finalRequestView"
android:layout_width="wrap_content"
android:layout_height="match_parent"
android:clickable="true"
android:visibility="visible">
<include
layout="#layout/fragment_transfer_new_version_container_child"
android:layout_width="match_parent"
android:layout_height="match_parent" />
</RelativeLayout>
</RelativeLayout>
Is it a possible to reverse position my view's? I mean,in my code last Layout is finalRequestView and in button click i would to my last view in first position,and other view's place on my view,
How i can solve this problem?

I try to reverse layout by following demo & it works as you want, please take a look
ReverseLayout.java
public class ReverseLayout extends AppCompatActivity {
LinearLayout llRoot;
Button btReverseLayout;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.reverse_layout);
llRoot = (LinearLayout) findViewById(R.id.llRoot);
btReverseLayout = (Button) findViewById(R.id.btReverseLayout);
btReverseLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
ArrayList<View> alViews = new ArrayList<View>();
for (int i = llRoot.getChildCount() - 1; i >= 0; i--) {
View view = llRoot.getChildAt(i);
llRoot.removeViewAt(i);
alViews.add(view);
}
for (int j = 0; j < alViews.size(); j++) {
llRoot.addView(alViews.get(j));
}
}
});
}
}

Listview setOnItemClickListener won't trigger

I am trying to change programmatically the background color of ListView item when the user tap on it. I am trying to implement a solution using setOnItemClickListener, but I have trouble making the listener work. Here is my code:
ArrayList<Integer> menuIcons = app.Theme.Icons.getMenuPanelIconList();
ArrayList<String> menuText = app.Languages.Active.getMenuPanelItemNames();
listview_menu = (ListView) findViewById(R.id.listview_menu);
listview_menu.setBackgroundColor(Color.parseColor("#" + app.Theme.ThemeBackColor));
MenuPanelListViewAdapter menuPanelListViewAdapter = new MenuPanelListViewAdapter(ActivityMain.this, menuIcons, menuText);
listview_menu.setAdapter(menuPanelListViewAdapter);
listview_menu.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adpterView, View view, int position,
long id) {
for (int i = 0; i < listview_menu.getChildCount(); i++) {
if(position == i ){
listview_menu.getChildAt(i).setBackgroundColor(Color.BLUE);
}else{
listview_menu.getChildAt(i).setBackgroundColor(Color.TRANSPARENT);
}
}
}
});

First change background of all item to transperent then set clicked view's background to your desired color like below.
MenuPanelListViewAdapter menuPanelListViewAdapter = new MenuPanelListViewAdapter(ActivityMain.this, menuIcons, menuText);
listview_menu.setAdapter(menuPanelListViewAdapter);
listview_menu.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> adpterView, View view, int position,
long id) {
for (int i = 0; i < listview_menu.getChildCount(); i++) {
listview_menu.getChildAt(i).setBackgroundColor(Color.TRANSPARENT);
}
view.setBackgroundColor(Color.BLUE);
menuPanelListViewAdapter.notifyDataSetChanged(); // this is importent
}
});

implement Globe-Weis File Folder in android

i want to implement Globe-Weis File Folder like picture below which by clicking on green button it scrolling smoothly up and by clicking on the green button again ,the folder page scrolling down smoothly.
what i try so far was putting three scrollView in a frameLayout , and to open and close it
if (!underIsOpen) {
ObjectAnimator
.ofInt(sv_Under, "scrollY",
findViewById(R.id.ll_under_botton).getTop())
.setDuration(1000).start();
underIsOpen = true;
} else {
ObjectAnimator
.ofInt(sv_Under, "scrollY",
findViewById(R.id.ll_under_s_part).getTop())
.setDuration(1000).start();
underIsOpen = false;
}
but it just work on the scrollView which is on top
my code is:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.test3);
ll_under_s_part = (LinearLayout) findViewById(R.id.ll_under_s_part);
sv_Under = (ScrollView) findViewById(R.id.scrollView1);
sv_Mid = (ScrollView) findViewById(R.id.scrollView2);
sv_Top = (ScrollView) findViewById(R.id.scrollView3);
}
public void onClick_under_left(View v) {
Toast.makeText(getApplicationContext(), "under layout",
Toast.LENGTH_SHORT).show();
if (!underIsOpen) {
ObjectAnimator
.ofInt(sv_Under, "scrollY",
findViewById(R.id.ll_under_botton).getTop())
.setDuration(1000).start();
underIsOpen = true;
} else {
ObjectAnimator
.ofInt(sv_Under, "scrollY",
findViewById(R.id.ll_under_s_part).getTop())
.setDuration(1000).start();
underIsOpen = false;
}
}
public void onClick_mid_left(View v) {
Toast.makeText(getApplicationContext(), "mid layout",
Toast.LENGTH_SHORT).show();
}
public void onClick_top_left(View v) {
Toast.makeText(getApplicationContext(), "top layout",
Toast.LENGTH_SHORT).show();
if (!topIsOpen) {
ObjectAnimator
.ofInt(sv_Top, "scrollY",
findViewById(R.id.ll_top_botton).getTop())
.setDuration(1000).start();
topIsOpen = true;
} else {
ObjectAnimator
.ofInt(sv_Top, "scrollY",
findViewById(R.id.ll_top_s_part).getTop())
.setDuration(1000).start();
topIsOpen = false;
}
}

the second way i tried was using animation but no success to result i am looking for :
public void SlideUP(View view, Context context) {
view.startAnimation(AnimationUtils.loadAnimation(context,
R.anim.slid_up));
}
public void SlideDown(View view, Context context) {
view.startAnimation(AnimationUtils.loadAnimation(context,
R.anim.slid_down));
}
any other way that i can implement this?

I don't think adding so may layout on a single screen with scrollbars is a good idea, you can apply simple frame layouts and list them accordingly and when clicking on any of the desired folder icons just animate it towards top, and it will also show the content of the folder.

you could customize this library to do that, I have done a similar kind of app and applied the same library with my custom changes.

Following is my MainActivity.java
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.custom_lock);
startService(new Intent(this, MyService.class));
TextView placexml = (TextView) findViewById(R.id.place1);
if (placexml == null)
System.out.println("placexml");
String place = "work";
//System.out.println("place: "+place);
placexml.setText(place);
boolean isApiRunning = ContextSdk
.isSemusiSensing(getApplicationContext());
if (isApiRunning)
Api.stopContext();
else {
SdkConfig config = new SdkConfig();
config.setPlacesAccuracyLevel(PlacesAccuracyLevel.EAccuracyHigh);
config.setActivityAccuracyLevel(ActivityAccuracyLevel.EAccuracyHigh);
config.setActivityTrackingAllowedState(true);
config.setAnalyticsTrackingAllowedState(true);
config.setDemographicsTrackingAllowedState(true);
config.setPedometerTrackingStateAllowed(true);
config.setPlacesTrackingAllowedState(true);
config.setRuleEngineEventStateAllowed(true);
Api.startContext(getApplicationContext(), config);
}
// reloadRssHandler.postDelayed(relaodRssRunnable, time);
//updateUILayer();
/*
txt1.setOnClickListener(new OnClickListener() {
#Override public void onClick(View arg0) { // TODO Auto-generated
method stub System.out.println("finishing......."); finish();
}
});
*/
}
When I run this program, "placexml" gets printed on console. I don't know, why this is happening. place1 is returning null from xml. Please help.

Change lines
android:name="#+id/place1"
to
android:id="#+id/place1"
You need to set ID instead of name.

setContentView(R.layout.custom_lock);
Wrong name of your layout "custom_layout"?

Try changing
<TextView
android:name="#+id/place1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white"
android:gravity="center"
android:text="Place"
android:textColor="#000000" />
with
<TextView
android:id="#+id/place1"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#android:color/white"
android:gravity="center"
android:text="Place"
android:textColor="#000000" />
