android:padding="5dp"
android:clickable="true"
android:textAppearance="?android:attr/textAppearanceMedium"
android:textStyle="bold" />
</LinearLayout>
My TextView ClickEvent not working ...please help me
Class Code
TextView view= (TextView) findViewById(R.id.btn);
view.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(getApplicationContext(), "Press",
Toast.LENGTH_SHORT).show();
}
});
You didn't call show method of Toast,so you have no idea whether TextView click event did happen or not.
Try this:
Toast.makeText(getApplicationContext(), "Press",
Toast.LENGTH_SHORT).show(); // don't miss show method.

I used a SlidingDrawer like in this tutorial
It works in a LinearLayout, but there is always a whitespace depending of the hight of the slider and all other stuff show up below the whitespace.
The soloution should be to use a Relative Layout. This deletes the whitespace but the handlerbutton from the slider seems to be under the content in the scrollview and don't do anything by clicking on it. See the screenshot
MainActivity.xml
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

android:layout_height="match_parent"
android:orientation="vertical">
<include
android:id="#+id/tbar"
layout="#layout/primerdivisor" />
<SlidingDrawer

android:layout_width="wrap_content"
android:layout_height="150dp"

The slider should overlap the scrollview when its whiped out
In view hierarchy terms, views defined at the beginning of your layout XML are "deeper" than those defined later.
In your case your ScrollView is added to the hierarchy after your SlidingDrawer so what your seeing is to be expected.
Move your SlidingDrawer to below your ScrollView and it should be above it.
I have the following Layout:
<LinearLayout
android:id="#+id/group_button_layout"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:layout_alignParentBottom="true"
android:gravity="center"
android:layout_centerHorizontal="true">
<Button
android:id="#+id/group_button_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:text="Week"/>
<Button
android:id="#+id/group_button_2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:padding="0dp"
android:text="Month"/>
<Button
android:id="#+id/group_button_3"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:text="Quarter"/>
<Button
android:id="#+id/group_button_4"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:text="Half Year"/>
</LinearLayout>
I created the onClickListener on layout like that:
private void initViews() {
mGroupedButtonLayout = (LinearLayout) findViewById(R.id.group_button_layout);
}
private void initListeners() {
mGroupedButtonLayout.setOnClickListener(mButtonGroupListener);
}
And I thought that after click on a button onClick event will be triggered:
private View.OnClickListener mButtonGroupListener = new View.OnClickListener() {
public void onClick(View v) {
Logger.d("Clicked");
Logger.d(String.valueOf(v.getId()));
// do something when the button is clicked
}
};
Is it possible to catch onClick event on every button without the need to create a listener for each button?
You could set the android:onClick attribute for the buttons, and handle your logic in the method you point it to.
XML
<Button
android:id="#+id/group_button_1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:textSize="12sp"
android:text="Week"
android:onClick="doButtonClick"/>
Java
public void doButtonClick(View v) {
switch(v.getId()) {
case R.id.group_button_1:
//do whatever for this button
break;
default:
break;
}
Hy.... I'm making a simple project on eclipse. I'm using relative layout as shown below :
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:gravity="center"
tools:context=".ProfileActivity"
>
<Button
android:id="#+id/Prof_edit_btn"
android:layout_below="#+id/Prof_LL"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Edit"
android:layout_marginTop="17dp"
android:layout_centerHorizontal="true"
/>
<LinearLayout
android:layout_below="#+id/Prof_LL"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:orientation="horizontal"
android:layout_centerHorizontal="true"
>
<Button
android:id="#+id/Prof_save_btn"
android:layout_below="#+id/Prof_LL"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="save"
android:layout_marginTop="17dp"
android:layout_centerHorizontal="true"
android:visibility="invisible"
android:clickable="false"
/>
<Button
android:id="#+id/Prof_batal_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="Batal"
android:layout_marginTop="17dp"
android:visibility="invisible"
android:clickable="false"
/>
</LinearLayout>
</RelativeLayout>
In the main activity, I've made a simple onClicklistener for Edit and Save button as shown below :
mEdit = (Button)findViewById(R.id.Prof_edit_btn);
mEdit.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
mBatal.setVisibility(View.VISIBLE);
mBatal.setClickable(true);
mSave.setVisibility(View.VISIBLE);
mSave.setClickable(true);
mEdit.setVisibility(View.INVISIBLE);
}
});
mSave = (Button)findViewById(R.id.Prof_save_btn);
mSave.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
mEdit.setVisibility(View.VISIBLE);
mBatal.setVisibility(View.INVISIBLE);
mSave.setVisibility(View.INVISIBLE);
Toast.makeText(getApplicationContext(), "Data Anda berhasil disimpan", Toast.LENGTH_SHORT).show();
}
});
Well... As we can see from my layout xml, only EDIT button will be visible on the start, then SAVE and BATAL button will be visible when EDIT is clicked by user according to the code program within setonclick listener of EDIT button. And as soon as EDIT button is clicked it will be invisible.... The problems here are WHen I clicked EDIT button, only SAVE button will be visible and BATAL button will be visible when SAVE button is clicked, another problem that I'm facing now is EDIT button is not invisible at all when I click it.... So.. anyone can help me with this problem please...??? :'(
Thanks in advance....
Naaah... I found my own solution... Just set the visibility of SAVE btn and BATAL btn to GONE... And it's all done.... :-)
<Button
android:id="#+id/Prof_save_btn"
android:layout_below="#+id/Prof_LL"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="save"
android:layout_marginTop="17dp"
android:layout_centerHorizontal="true"
android:visibility="gone"<-----------=
android:clickable="false"
/>
<Button
android:id="#+id/Prof_batal_btn"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_centerHorizontal="true"
android:text="Batal"
android:layout_marginTop="17dp"
android:visibility="gone"<-----------=
android:clickable="false"
/>
In my android code, I have implemented onclick event on 3 textviews using following code. But nothing happens when they are clicked. What is wrong ?
<TextView
android:id="#+id/tv1"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#drawable/menucircle"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:onClick="selectit"
android:textColor="#ffffff"
/>
public void selectit(View v)
{
Log.d("tv0","ok");
if(v.getId()==tv1.getId())
{Log.d("tv1","ok");
selectoption(1);
Log.d("tv1","ok");
}
if(v.getId()==tv2.getId())
{Log.d("tv2","ok");
selectoption(2);
}
if(v.getId()==tv3.getId())
{Log.d("tv3","ok");
selectoption(3);
}
}
Add this into your xml
android:clickable="true"
You probably need to have this code in your xml
android:clickable="true"
Or Set the Clicklistenner to TextView via code by
TextView btn=(TextView) findViewById(R.id.tv1);
btn.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
selectit(v);
}
});
It will automatically make it clickable so no need of android:clickable="true"
You can set the click handler in xml with these attribute:
android:clickable="true"
Don't forget the clickable attribute, without it, the click handler isn't called.
main.xml
<TextView
android:id="#+id/tv1"
android:layout_width="40dp"
android:layout_height="40dp"
android:background="#drawable/menucircle"
android:layout_alignParentLeft="true"
android:layout_centerVertical="true"
android:onClick="selectit"
android:clickable="true"
android:textColor="#ffffff"
/>
i hope it will help u all the best
Try like below:
android:onClick="onClick"
android:clickable="true"
My textview:
<TextView
android:id="#+id/click"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="Click Me"
android:textSize="55sp"
android:onClick="onClick"
android:clickable="true"/>
Main Activity:
public class MyActivity extends Activity {
public void onClick(View v) {
...
}
}
I have an app, which shows toast below the actionbar. I'm using Crouton library for displaying toast. Here I'm placing custom layout for toast, that layout contains one textview and one button (for close option). So Toast appears with button. If I click that it should close the toast but nothing happens.. Below Code for this example. Any Help Appreciated
MainActivity.java
public class MainActivity extends SherlockActivity implements OnClickListener {
private View customToastView;
private TextView customToastMessageView;
private Button customToastCloseButton;
private Button doneButton;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
doneButton = (Button) findViewById(R.id.done_button);
customToastView = getLayoutInflater().inflate(R.layout.toast_custom_layout, null);
customToastMessageView = (TextView) customToastView.findViewById(R.id.messages);
customToastCloseButton = (Button) customToastView.findViewById(R.id.close_button);
customToastCloseButton.setOnClickListener(this);
doneButton.setOnClickListener(this);
}
#Override
public void onClick(View v) {
switch (v.getId()) {
case R.id.done_button:
Crouton.cancelAllCroutons();
customToastMessageView.setText("Message");
Crouton.show(this, customToastView);
break;
case R.id.close_button:
Crouton.cancelAllCroutons();
break;
}
}
}
