Is it possible to highlight or change the image of a button to another image Onclick() of a button ?
this is my xml for the button
<Button android:layout_height="wrap_content"
android:textColor="#000000"
android:gravity="center_horizontal|center_vertical" android:layout_gravity="center_horizontal|center_vertical"
android:focusableInTouchMode="true"
android:background="#drawable/button"
android:layout_width="wrap_content"
android:soundEffectsEnabled="true"
android:text="START"
android:focusable="true"
android:id="#+id/start"></Button

yes you can, first get the reference of both buttons using findViewById() method, then do this
button1.setOnclickListener(new OnClickListener(){
protected void onClick(View v){
button2.setBackground(Color.WHITE);
}
});
edit
override another method.
button1.setOnFocusChangedListener(new OnFocusChangedListener(){
protected void onFocusChange()
{
button2.setBackground("your 1st image")
}
});
You can use setImageRessource method :
ImageButton.setOnclickListener(new OnClickListener(){
protected void onClick(View v){
imageButton.setImageResource(R.id.newImage)
}
});

I have LinearLayout which has 2 children which are used only as a preview. LinearLayout functionality here is same as Button. I want to disable any interaction with its children but make LinearLayoutclickable by using onClickListener. Currently if I click on Spinner it will not trigger onClickListener of LinearLayout. I also called spinner.isEnabled = false in code.
Layout:
<LinearLayout
android:id="#+id/clickableLayout"
android:orientation="horizontal"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:clickable="true"
android:focusable="true"
android:focusableInTouchMode="true"
android:gravity="center_vertical">
<Spinner
android:id="#+id/picker"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:duplicateParentState="true"
android:enabled="false"
android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false">
</Spinner>
<TextView
android:id="#+id/text1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:layout_marginTop="16dp"
android:layout_marginBottom="16dp"
android:textColor="#color/colorBlack"
android:textSize="14dp"
android:enabled="false"
android:clickable="false"
android:focusable="false"
android:focusableInTouchMode="false"
android:singleLine="true"
android:duplicateParentState="true"
android:maxLength="9"/>
</LinearLayout>
Make on Click Listener for All of the views and then call your function, so it does not matter on which view you click. It will always trigger that function.
LinearLayout linearLayout;
TextView textView;
Spinner spinner;
linearLayout = findViewById(R.id.clickableLayout);
spinner = findViewById(R.id.picker);
textView = findViewById(R.id.text1);
linearLayout.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
myFunction();
}
});
spinner.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
myFunction();
}
});
textView.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
myFunction();
}
});
}
private void myFunction() {
Toast.makeText(getApplicationContext(),"Clicked",Toast.LENGTH_LONG).show();
}
I have simple layout with EditText and a button.
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:id="#+id/linearLayout"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:orientation="horizontal"
android:clickable="true"
android:focusable="true">
<EditText
android:id="#+id/editText"
android:layout_width="0dp"
android:layout_weight="1"
android:layout_height="wrap_content"
android:focusable="false"/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Button"/>
</LinearLayout>
I don't want EdiText to be editable and want to handle click on complete layout
public class MainActivity extends AppCompatActivity {
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
findViewById(R.id.linearLayout).setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(MainActivity.this, "click", Toast.LENGTH_SHORT).show();
}
});
}
}
but it is not working I mean There is no Toast message when I am clicking.
as #Liem Vo said in the comments: you should add android:clickable="false" to the button, and make sure not to add a click listener in java.
becuse the event is handled by the child view.
for the 'EditText' you can call the parents click listener manually:
editText.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
View parent = (View) v.getParent();
parent.performClick();
}
});
please refer to this question: onClick not triggered on LinearLayout with child
How is it possible to hyperlink a button on a android application. this is my code can you please edit it and then reply as it is very needed my app is in a short time limit
<Button
android:id="#+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignLeft="#+id/textView1"
android:layout_below="#+id/textView1"
android:layout_marginLeft="13dp"
android:layout_marginTop="48dp"
android:text="GTA 3" />
You want to bind an onClickListener to your button. Put this in your activity:
Button button1 = (Button) findViewById(R.id.button1);
button1.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// do your stuff here
}
});
I am developing a simple game and in an activity I have 2 image buttons:
<ImageButton
android:id="#+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#string/desc"
android:src="#drawable/img1"
android:onClick="btn1_click" />
<ImageButton
android:id="#+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#string/desc"
android:src="#drawable/img2"
android:onClick="btn2_click" />
And I am showing some animations when buttons are clicked:
public void btn1_click(View v) {
v.startAnimation(animLeftTranslate);
}
public void btn2_click(View v) {
v.startAnimation(animRightTranslate);
}
Of course, only the clicked button is being animated but what I want to do is to show animation for both two buttons when one of them are clicked. How can I do this?
Instead of using android:onClick, you can do it in java code:
ImageButton btn1 = (ImageButton) findViewById(R.id.bt1);
ImageButton btn2 = (ImageButton) findViewById(R.id.bt2);
View.OnClickListener listener = new View.OnClickListener() {
#Override
public void onClick(View v) {
btn1.startAnimation(animRightTranslate);
btn2.startAnimation(animRightTranslate);
}
};
btn1.setOnClickListener(listener);
btn2.setOnClickListener(listener);`
`
You can accomplish this by your own approach i.e. using android:onClick attribute:
Assign one function to both ImageButton for example btns_clicked(). So add android:onClick='btns_clicked' to both your buttons. And in that function write:
public void btns_clicked(View v) {
View btn1 = findViewById(R.id.btn1);
View btn2 = findViewById(R.id.btn2);
btn1.startAnimation(animLeftTranslate);
btn2.startAnimation(animRightTranslate);
}
you can do this as describe below.
<ImageButton
android:id="#+id/btn1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#string/desc"
android:src="#drawable/img1"
android:onClick="btn_click" />
<ImageButton
android:id="#+id/btn2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:contentDescription="#string/desc"
android:src="#drawable/img2"
android:onClick="btn_click" />
and in activity, you have to use
public void btn_click(View v) {
if(v.getId() == R.id.btn1)
v.startAnimation(animLeftTranslate);
else if(v.getId() == R.id.btn2)
v.startAnimation(animRightTranslate);
}
i have this layout, but the button is not clickable.
i tried solutions from previous posts, such as adding android:focusable="false" to the button or listview or the linear layout but it didnt work. i tried adding : button.setFocusable(false) after the button OnClickListener but also didnt work. i even tried adding: android:descendantFocusability="blocksDescendants" to the main linear layout but the problem still exists.
Thanks.
<LinearLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="horizontal"
<EditText
android:id="#+id/search_field"
android:layout_width="181dp"
android:layout_height="wrap_content"
android:layout_weight="1.25"
android:ems="10"
android:hint="Search"
android:textColor="#1F6260" />
<Button
android:id="#+id/refresh_button"
android:layout_width="34dp"
android:layout_height="32dp"
android:background="#drawable/refresh3" />
</LinearLayout>
<ListView
android:id="#+id/list2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:divider="#b5b5b5"
android:dividerHeight="1dp"
android:listSelector="#drawable/list_selector">
</ListView>
</LinearLayout>
Java code:
refresh= (Button)myFragmentView.findViewById(R.id.refresh_button);
refresh.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
((MainTabs)getActivity()).refresh();
((MainTabs)getActivity()).getUsersList();
}
});
Added the toast in the onclick method and it showed, so my code isn't working and nothing is wrong with the button. Sorry for this inconvenience.
Thanks.
Two ways to achieve this
1.
Change your button like this
<Button
android:id="#+id/refresh_button"
android:layout_width="34dp"
android:layout_height="32dp"
android:background="#drawable/refresh3"
android:clickable="true"
android:onClick="buttonClick" />
then create a method inside your activity which have to pass your View as parameter like this.
public void buttonClick(View v) {}
or you can follow the second way
2.
Button button;
button = (Button) findViewById(R.id.refresh_button);
button.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
}
});
Hope this will help you.
