Your code works fine, except you set the listener for b2 twice. Typo maybe?
If you are facing connection errors, just add the Internet permission to AndroidManifest.xml.
<uses-permission android:name="android.permission.INTERNET"/>
I am a newbie to Android programming and now I want to create a ViewFlipper or ViewSwitcher for 2 views which will switch view between 1 and 2 columns. The problem is that the 1st view is ok, but when I use showNext() or showPrevious(), the 2nd view shows as blank, and I have been completely out of mind thinking what is wrong. I have tried ViewFlipper and ViewSwitcher with the same results.
layout_devicelistmainswitcher.xml
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent">

android:layout_height="70dp"
android:contentDescription="Grid/List View"

android:layout_gravity="right" />

mainactivity.java
public class activity_devicelist extends AppCompatActivity {
GridView grid;
Boolean viewtype = true;
ViewFlipper switcher;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.layout_devicelistmainswitcher);
Button button = (Button) findViewById(R.id.viewbutton);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(activity_devicelist.this, "Button Clicked", Toast.LENGTH_SHORT).show();
switcher = (ViewFlipper) findViewById(R.id.vflipper);
switcher.showPrevious();
}
});
}
}
Take your findViewById out like below,then It should work
switcher = (ViewFlipper) findViewById(R.id.vflipper);
button.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
Toast.makeText(activity_devicelist.this, "Button Clicked", Toast.LENGTH_SHORT).show();
switcher.showPrevious();
}
});
I write a program with FrameLayout, when i clicked on the first button, the program show introduce.xml but when i clicked on the second button, the program Force Class. i think because i use Button in product.xml file because when i changed button to imageView, the program runs good.

Its a typo. product.xml only has 1 T in Button.
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;
}
}
}
toast_custom_layout.xml
<?xml version="1.0" encoding="utf-8"?>

I'm trying to use a button to start a new activity like this:
public class MainActivity extends Activity implements OnClickListener {
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
((Button) findViewById(R.id.button1)).setOnClickListener(this);
((Button) findViewById(R.id.button2)).setOnClickListener(this);
}
public void onClick(View view) {
Button clickedBtn = (Button) view;
switch (clickedBtn.getId()) {
case R.id.button1: startActivity(new Intent(this, NewActivity.class));
break;
case R.id.button2: startActivity(new Intent(this, AnotherActivity.class));
break;
}
}
}
But nothing seems to happen when I click on either button. I guess it's because the onClick method does not know which button is actually clicked...but I'm not sure how I can fix this...please advice, thanks!
Edit: added XML file
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical"
android:background="#000000">
<ScrollView
android:layout_width="fill_parent"
android:layout_height="fill_parent">
<LinearLayout android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:orientation="vertical">
<Button android:id="#+id/button1"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="first button" />
<Button android:id="#+id/button2"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="second button" />
</LinearLayout>
</ScrollView>
</LinearLayout>
I put the code in the wrong file; everything is working now. Thanks!
