I create a button and TextView
when I press the button to visible the TextView
its working good but my question was when same button pressed invisible the TextView
how can i do this? This is my code:
<Button
android:id="@+id/btn1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Button"
/>
<TextView
android:id="@+id/pas_rules"
android:layout_width="fill_parent"
android:layout_height="30dp"
android:text="welcome"
android:visibility="gone"/>
main activity:
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
textview.setVisibility(View.VISIBLE);
}
});
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
textview.setVisibility(textview.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE);
// which is just like:
/*
if(textview.getVisibility() == View.VISIBLE)
textview.setVisibility(View.GONE);
else
textview.setVisibility(View.VISIBLE);
*/
}
});
you can achieve this by checking the visibility of the view:-
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
if(textview.getVisibility()==View.GONE)
{
textview.setVisibility(View.VISIBLE);
}
else
{
textview.setVisibility(View.GONE);
}
}
});
Another Way
<Button
android:id="@+id/btn1"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:text="Button"
android:onClick="Button_Click"
android:clickable="true"
/>
<TextView
android:id="@+id/pas_rules"
android:layout_width="fill_parent"
android:layout_height="30dp"
android:text="welcome"
android:visibility="gone"/>
//Now Declare Button_Click Function in your Java Class
public void Button_Click(View i)
{
textview.setVisibility(textview.getVisibility() == View.VISIBLE ? View.GONE : View.VISIBLE);
// Do your Code in here
}
You can check whether your Textview is visible or not if you click on the button. If it's visible, you can remove the visibility, if not, you can make it visible. You can find a solution here: How to check TextView Visibility using IF You have to use the textview.getVisibility() method and check it to View.VISIBLE. If it is visible you have to set your textview invisible: textview.setVisibility(View.GONE);
Your code could look like:
button.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View arg0) {
if (textview.getVisibility()==View.VISIBLE){
textview.setVisibility(View.GONE);
}
else{
textview.setVisibility(View.VISIBLE);
}
});
