I am creating an android app which has a navigation drawer. The header of the drawer has a circular ImageView and some TextViews. I want to make them clickable. I have been trying to fix this for hours but in vain. After searching the web for a while I got hints (though I am not sure) that the header is not clickable at least by default. Is it true? Is it possible to make the views in the header of my drawer clickable? I have tried setting setClickable() to true etc but nothing works. Please help. Thanks in advance !!!
You can get Individual component event by getting header view like this.
addHeaderView(header, null, false) disable click event of entire header but you can get component event using View.
View header = View.inflate(mContext, R.layout.header, null);
mDrawerList.addHeaderView(header, null, false);
ImageView image = (ImageView) header.findViewById(R.id.image_id);
image.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
Log.e("","Click event")
}
});
im looking for creating an action bar like this:
X Cancel -------------- add +
where X and + are icons. So im using getActionBar.setIcon to set the X. home action to set the Cancel title. the ---------- stuf is just blank space, An action with title and icon to set the "add" and the "+", the problem is that by default the action shows the icon to the left side of the title. so im having:
X Cancel -------------- + add
Is there a way to flip it?
or maeby a better way to do this....
i realy was unmotivated to use a custom layout for the action bar cuz i think i lose the power of action items...
here is the menu xml:
<item
android:id="#+id/action_create_key"
android:icon="#drawable/plus"
android:title="#string/action_create"
android:showAsAction="always|withText"/>
Thanks a lot for ur time and help...
Why would you not like to use custom layout for action bar? you can also add the actions to the items in the custom layout too.
Simply create the custom layout of your desired design and use following code to handle it
final ViewGroup actionBarLayout = (ViewGroup) getLayoutInflater().inflate(R.layout.action_bar, null);
final ActionBar actionBar = getActionBar();
actionBar.setDisplayShowHomeEnabled(false);
actionBar.setDisplayShowTitleEnabled(false);
actionBar.setDisplayShowCustomEnabled(true);
actionBar.setCustomView(actionBarLayout);
ImageView cancel = (ImageView) actionBarLayout.findViewById(R.id.cancel_icon);
ImageView add = (ImageView) actionBarLayout.findViewById(R.id.add_icon);
cancel.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
//add your functionaity
}
});
This isn't something that can be done using stock ActionBar items. You could consider using the Done/Discard custom action bar, which uses a custom layout of two buttons as the action bar, replacing 'DiscardandDonefor yourCancelandAdd. If you are using the provided [DoneBarActivity source code][2], you'd want to change the right hand layout to usedrawableRightrather thandrawableLeft` to position your icon to the right of the text.
I am using FragmentTabHost to implement bottom tabs with icon and label but following sentence shows only label
mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator("Simple",getResources().getDrawable(R.drawable.ic_launcher)),
Fragment1.class, b);
I also see somewhere following works properly
setIndicator(View);
but I don't know syntax to set custom view in setIndicator
plz help
Thanks...
I make custom view and set it as setIndicator(View v);
View chatView=LayoutInflater.from(this).inflate(R.layout.chat_icon,null);
mTabHost.addTab(mTabHost.newTabSpec("simple").setIndicator(chatView),
Fragment1.class, b);
Is there a way to render a view on top of the action bar? I want to create a small tip box that will point the user to an item in the action bar. I know that a Toast with a set view will be rendered above the action bar. Does anyone know how to do this with a view?
I have attempted using FrameLayout with layout_gravity="top" and inflating a view and then adding it to the running activity's layout.
I appreciate you in advance.
Edit:
Here is an image of what I was thinking:
Edit:
Perhaps some more detail is needed. I am looking for a way, or to find out if it is even possible to add a view to the view hierarchy of the activity so that it is rendered last.
Similar to CSS, I want a higher z-index order for this particular view ( the blue floating box in the image), such that it would be rendered on top of the Action Bar region in the activity. The view is in no way associated with Action Bar, it is simply drawn on top of it.
I was trying to achieve something else but I needed a solution similar to this. I needed to draw an opaque layer covering the whole screen, even the action bar--sort of like a dialog. I did so this way:
ViewGroup vg = (ViewGroup)(getWindow().getDecorView().getRootView());
vg.addView(myNewView, params);
this can be used to draw anything anywhere on the screen.
UPDATE: You really shouldn't be using ActionBar anymore, you wouldn't have this issue in the first place if you were using Toolbar like Android recommends. Toolbar would go inside your activity xml like a regular view and you can can do whatever you want to it. And its fully backwards compatible.
https://developer.android.com/training/appbar/setting-up
After struggling with it myself quite some time, here's the solution (tested it - working good):
The general steps are:
Create a wrapper view
Detach the screen view children, place the wrapper, and attach the children
Inflate the content to the children
Controling the wrapper will help you control exactly the action bar and the content below it all together.
Now, using the wrapper, you can add "brothers" to the actionbar/main area. That brother is exactly what you described in your image.
Let's see some code.
First, create a method to help create a wrapper view. the wrapper will be placed between the entire screen and the content of your app. being a ViewGroup you can later on fully control it's content.
private ViewGroup setContentViewWithWrapper(int resContent) {
ViewGroup decorView = (ViewGroup) this.getWindow().getDecorView();
ViewGroup decorChild = (ViewGroup) decorView.getChildAt(0);
// Removing decorChild, we'll add it back soon
decorView.removeAllViews();
ViewGroup wrapperView = new FrameLayout(this);
// You should set some ID, if you'll want to reference this wrapper in that manner later
//
// The ID, such as "R.id.ACTIVITY_LAYOUT_WRAPPER" can be set at a resource file, such as:
// <resources xmlns:android="http://schemas.android.com/apk/res/android">
// <item type="id" name="ACTIVITY_LAYOUT_WRAPPER"/>
// </resources>
//
wrapperView.setId(R.id.ACTIVITY_LAYOUT_WRAPPER);
// Now we are rebuilding the DecorView, but this time we
// have our wrapper view to stand between the real content and the decor
decorView.addView(wrapperView, LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
wrapperView.addView(decorChild, decorChild.getLayoutParams());
LayoutInflater.from(this).inflate(getActivityLayout(),
(ViewGroup)((LinearLayout)wrapperView.getChildAt(0)).getChildAt(1), true);
return wrapperView;
}
Now, interfere with the regular Activity creation, and instead of using setContentView, use the method we've created.
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
// DON'T CALL `setContentView`,
// we are replacing that line with this code:
ViewGroup wrapperView = setContentViewWithWrapper(R.layout.activity_layout);
// Now, because the wrapper view contains the entire screen (including the notification bar
// which is above the ActionBar) I think you'll find it useful to know the exact Y where the
// action bar is located.
// You can use something like that:
ViewGroup actionBar = (ViewGroup)((LinearLayout)wrapperView.getChildAt(0)).getChildAt(0);
int topOffset = actionBar.getTop();
// Now, if you'll want to add a view:
// 1. Create new view
// 2. Set padding top - use "topOffset"
// 3. Add the view to "wrapperView"
// 4. The view should be set at front. if not - try calling to "bringToFront()"
}
That's about it.
Notes
I've used Android's hierarchy-viewer to understand what's the right hierarchy. (didn't guess those 0 and 1 indexes)
If you are using some kind of a menu drawer in your activity, you might have to configure it a little bit different since drawers are already creating that wrapper for you
I've learned a lot by looking at this great library
EDIT: Refer to #CristopherOyarzúnAltamirano Answer for further support on newer Android versions
Good luck!
There is a much simpler way to achieve this. ActionBar holds its layout in the class ActionBarContainer which simply inherits from FrameLayout. So in order to display something over the ActionBar you need to grab a reference to the ActionBarContainer and add your own custom View into it. Here is the code
int abContainerViewID = getResources().getIdentifier("action_bar_container", "id", "android");
FrameLayout actionBarContainer = (FrameLayout)findViewById(abContainerViewID);
LayoutInflater myinflater = getLayoutInflater();
View customView = myinflater.inflate(R.layout.yourCustomeViewLayout, null);
actionBarContainer.addView(customView);
I found this workaround based on #Sean answer:
//This is for Jelly, ICS, Honeycomb
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB && Build.VERSION.SDK_INT < Build.VERSION_CODES.JELLY_BEAN_MR2){
LayoutInflater.from(this).inflate(resContent, (ViewGroup)((LinearLayout)wrapperView.getChildAt(0)).getChildAt(1), true);}
//This is for KitKat and Jelly 4.3
else if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR2){
LayoutInflater.from(this).inflate(resContent, (ViewGroup) (((ViewGroup) wrapperView.getChildAt(0)).getChildAt(0)), true);}
//This is for Ginger
else{
LayoutInflater.from(this).inflate(resContent, (ViewGroup) ((LinearLayout)((FrameLayout) wrapperView.getChildAt(0)).getChildAt(0)).getChildAt(1), true);}
I found a much simpler way to do this.
I just applied android:translationZ="10dp" to the view which I need to be covering the action bar.
I chose 10dp but it can actually be anything you want as long as it is superior to the actionbar's elevation
<ImageView
android:layout_width="100dp"
android:layout_height="100dp"
android:translationZ="10dp"
android:src="#drawable/potatoe" />
Also, don't worry about Android studio's following warning :
"translationZ can't be used with API<21".
It will be ignored, but you don't really care because the toolbar shouldn't cover your view with APIs inferior to 21.
Try using ActionBar.setCustomView(). That's the only way to change the appearance of that area of the screen. You can't stick a View into the area "above" the ActionBar, because that area is basically controlled by the system. On the other hand, you can provide your own layout for it.
If you explain in more detail what you're trying to do, respondents might have some better design ideas.
https://github.com/michaelye/EasyDialogDemo
see the demo above,it may help you
dialog.setLocation(new location[])//point in screen
you could set the location[] yourself.
Use the android:actionLayout in your menu.xml file.
<?xml version="1.0" encoding="utf-8"?><menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="#+id/menu_id"
android:title="#string/menu_string_to_show"
android:icon="#drawable/ic_menu_icon_name"
android:showAsAction="always"
android:actionLayout="#layout/action_button_foo" /></menu>
Then create your action_button_foo.xml layout:
<?xml version="1.0" encoding="utf-8"?><TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:gravity="center"
android:text="#string/menu_string_to_show"
android:drawableLeft="#drawable/ic_menu_icon_name"
android:background="#drawable/bg_btn_action_bar"
android:clickable="true" />
To handle click do the following:
#Overridepublic boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.my_menu, menu);
final MenuItem item = menu.findItem(R.id.menu_id);
item.getActionView().setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
onOptionsItemSelected(item);
}
});
return super.onCreateOptionsMenu(menu);}
That's if :)
(Reference: http://www.vogella.com/articles/AndroidActionBar/article.html)Custom Views in the ActionBar
You can also add a custom View to the ActionBar. For this you use the setCustomView method for the ActionView class. You also have to enable the display of custom views via the setDisplayOptions() method by passing in the ActionBar.DISPLAY_SHOW_CUSTOM flag.
For example you can define a layout file which contains a EditText element.
<?xml version="1.0" encoding="utf-8"?>
<EditText xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/searchfield"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:inputType="textFilter" >
This layout can be assigned to the ActionBar via the following code. The example code allow attaches a listener to the custom view.
package com.vogella.android.actionbar.customviews;
import android.app.ActionBar;
import android.app.Activity;
import android.os.Bundle;
import android.view.KeyEvent;
import android.widget.EditText;
import android.widget.TextView;
import android.widget.TextView.OnEditorActionListener;
import android.widget.Toast;
public class MainActivity extends Activity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
ActionBar actionBar = getActionBar();
// add the custom view to the action bar
actionBar.setCustomView(R.layout.actionbar_view);
EditText search = (EditText) actionBar.getCustomView().findViewById(R.id.searchfield);
search.setOnEditorActionListener(new OnEditorActionListener() {
#Override
public boolean onEditorAction(TextView v, int actionId,
KeyEvent event) {
Toast.makeText(MainActivity.this, "Search triggered",
Toast.LENGTH_LONG).show();
return false;
}
});
actionBar.setDisplayOptions(ActionBar.DISPLAY_SHOW_CUSTOM
| ActionBar.DISPLAY_SHOW_HOME);
}
}
The explanations here are all too long:
Wrap your main layout file into a top level ViewGroup (e.g. wrap a CoordinatorLayout into a FrameLayout), then inject or declare the view in the new top level layout out. The view will appear above the action bar.
Hai, I am new android developer. I want to create a Tab host application . There will be 3 different tab items .Each item is attached with map view. I want to change the zoom label of each map when tab each item. How can i do it...
In each tab item , set programatically the following line with MapView:
mapView.setBuiltInZoomControls(true);
mapView.getController().setZoom(13); //set zoom level according to need for each tab item
Hope this will solve your issue.
Use this event
public void onTabChanged(String arg0) {
int currentTabvalue = tabHost.getCurrentTab();
if(currentTabvalue==0)
mapView.getController().setZoom(----);
else if(currentTabvalue==1)
mapView.getController().setZoom(----);
else if(currentTabvalue==2)
mapView.getController().setZoom(----);
}
I thinks this is the code you want to achieve this.
In this code you fill the value in the place of ----- according to your requirement.
I hope you have got your answer.
