How to redirect to another activity in android on click of an element
Here is my code for the Click item and print the data as a list.
listView = (ListView) layout.findViewById(R.id.listView1);
Notifcationadapter adapter = new Notifcationadapter(this, notifies);
listView.setAdapter(adapter);
listView.setOnItemClickListener(this);
}
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
View parentView = (View) view.getParent();
TextView value1 = ((TextView) parentView.findViewById(R.id.title));
String value = value1.getText().toString();
if (value.equals("Post"))
Toast.makeText(this, "Post", 1000).show();
if (value.equals("Request For travelling"))
Toast.makeText(this, "Request for travelling", 1000).show();
}
Here is my adapter:
public class Notifcationadapter extends BaseAdapter {
private static ArrayList<Notify> values;
Context context;
// List<RowItem> rowItems;
ViewHolder holder = null;
LinearLayout linear2;
DataBaseManager dbManager = new DataBaseManager(context);
ArrayList<Notify> notifies;
public Notifcationadapter(Context context, ArrayList<Notify> notifies) {
super();
this.context = context;
this.notifies = notifies;
}
/* private view holder class */
private class ViewHolder {
TextView txtTitle;
TextView txtDesc;
ImageView yesimage;
ImageView noimage;
TextView revresetime;
LinearLayout linear2;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.notifcationlistitem, null);
holder = new ViewHolder();
holder.linear2 = (LinearLayout) convertView.findViewById(R.id.linear2);
holder.txtDesc = (TextView) convertView.findViewById(R.id.desc);
holder.txtTitle = (TextView) convertView.findViewById(R.id.title);
holder.yesimage = (ImageView) convertView.findViewById(R.id.imageView1);
holder.noimage = (ImageView) convertView.findViewById(R.id.imageView2);
holder.revresetime = (TextView) convertView.findViewById(R.id.revresetime);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// holder.txtTitle.setText("Title");
String statustype = notifies.get(position).getNotificationType();
if (statustype.equals("1")) {
holder.txtDesc.setText(notifies.get(position).getNotificationDescrpiton());
holder.revresetime.setText(Functions.setLastSeenNotifcationTime(notifies.get(position).getNotificationDatetime()));
holder.txtTitle.setText("Request For travelling");
holder.yesimage.setVisibility(View.VISIBLE);
holder.noimage.setVisibility(View.VISIBLE);
} else {
holder.txtDesc.setText(notifies.get(position).getNotificationDescrpiton());
holder.txtTitle.setText("Post");
holder.revresetime.setText(Functions.setLastSeenNotifcationTime(notifies.get(position).getNotificationDatetime()));
holder.yesimage.setVisibility(View.GONE);
holder.noimage.setVisibility(View.GONE);
}
if (position % 2 == 0) {
convertView.setBackgroundColor(Color.parseColor("#ffffff"));
} else {
convertView.setBackgroundColor(Color.parseColor("#f5f6f1"));
}
holder.yesimage.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
Toast.makeText(context, "Yes", 10000).show();
holder.linear2.setVisibility(View.INVISIBLE);
}
});
holder.noimage.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Toast.makeText(context, "NO", 10000).show();
holder.linear2.setVisibility(View.INVISIBLE);
}
});
return convertView;
}
@Override
public int getCount() {
return notifies.size();
}
@Override
public Object getItem(int position) {
return notifies.get(position);
}
@Override
public long getItemId(int position) {
return position;
}
}
I am displaying data in a list view i wan i want to apply to the click function of an item so that in case a message in the list is displayed in the text view list then its item should click on it. Print a message if it asks for a trip then it should show a trip request but I cannot do that please help where I am doing wrong.

you get the same value because of this line
TextView value1 = ((TextView) parentView.findViewById(R.id.title));
to get the value String
in your adapter or arraylist you can do something like this.
I am assuming you have an arraylist of objects
//you arraylist contains object/class
String value1 = notifies.get(position).getTitle();
and using adapter
String value1 = adapter.getItem(position);
then a @Override
function getItem()
in your adapter
@Override
public String getItem(int position){
return notifies.get(position).getTitle();
}
then go to another activity according to your if statement
@Override
public void onItemClick(AdapterView<?> parent, View view, int position, long id) {
View parentView = (View) view.getParent();
String value = notifies.get(position).getTitle();
Intent i = null;
if (value.equals("Post")){
i = new Intent(context,PostActivity.class);
}
else if (value.equals("Request For travelling")){
i = new Intent(context,RequestActivity.class);
}
if(i !=null){
startActivity(i);
}
}

First remove the onitemclick listener from activity. and use this code -
listView.setOnItemClickListener(this); // remove this line
as well as remove onitem click-
@Override
public void onItemClick(AdapterView<?> parent, View view, int position,
long id) {
// TODO Auto-generated method stub
View parentView = (View) view.getParent();
TextView value1 = ((TextView) parentView.findViewById(R.id.title));
String value = value1.getText().toString();
if (value.equals("Post")) {
Toast.makeText(this, "Post", 1000).show();
}
if (value.equals("Request For travelling")) {
Toast.makeText(this, "Request for travelling", 1000).show();
}
}
**just add convertview click listener**
public class Notifcationadapter extends BaseAdapter {
private static ArrayList<Notify> values;
Context context;
// List<RowItem> rowItems;
ViewHolder holder = null;
LinearLayout linear2;
DataBaseManager dbManager = new DataBaseManager(context);
ArrayList<Notify> notifies;
public Notifcationadapter(Context context, ArrayList<Notify> notifies) {
super();
this.context = context;
this.notifies = notifies;
}
/* private view holder class */
private class ViewHolder {
TextView txtTitle;
TextView txtDesc;
ImageView yesimage;
ImageView noimage;
TextView revresetime;
LinearLayout linear2;
}
public View getView(int position, View convertView, ViewGroup parent) {
LayoutInflater mInflater = (LayoutInflater) context
.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
if (convertView == null) {
convertView = mInflater.inflate(R.layout.notifcationlistitem, null);
holder = new ViewHolder();
holder.linear2 = (LinearLayout) convertView
.findViewById(R.id.linear2);
holder.txtDesc = (TextView) convertView.findViewById(R.id.desc);
holder.txtTitle = (TextView) convertView.findViewById(R.id.title);
holder.yesimage = (ImageView) convertView
.findViewById(R.id.imageView1);
holder.noimage = (ImageView) convertView

holder.revresetime = (TextView) convertView
.findViewById(R.id.revresetime);
convertView.setTag(holder);
} else {
holder = (ViewHolder) convertView.getTag();
}
// holder.txtTitle.setText("Title");
String statustype = notifies.get(position).getNotificationType();
if (statustype.equals("1")) {
holder.txtDesc.setText(notifies.get(position)
.getNotificationDescrpiton());
holder.revresetime.setText(Functions
.setLastSeenNotifcationTime(notifies.get(position)
.getNotificationDatetime()));
holder.txtTitle.setText("Request For travelling");
holder.yesimage.setVisibility(View.VISIBLE);
holder.noimage.setVisibility(View.VISIBLE);
}
else {
holder.txtDesc.setText(notifies.get(position)
.getNotificationDescrpiton());
holder.txtTitle.setText("Post");
holder.revresetime.setText(Functions
.setLastSeenNotifcationTime(notifies.get(position)
.getNotificationDatetime()));
holder.yesimage.setVisibility(View.GONE);
holder.noimage.setVisibility(View.GONE);
}
if (position % 2 == 0) {
convertView.setBackgroundColor(Color.parseColor("#ffffff"));
}
else {
convertView.setBackgroundColor(Color.parseColor("#f5f6f1"));
}
holder.yesimage.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
Toast.makeText(context, "Yes", 10000).show();
holder.linear2.setVisibility(View.INVISIBLE);
}
});
holder.noimage.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
Toast.makeText(context, "NO", 10000).show();
holder.linear2.setVisibility(View.INVISIBLE);
}
});
convertView.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
// TODO Auto-generated method stub
// write your code to redirect to another activity like this way
Intent i = new Intent(context,
Youractivity.class);
context.startActivity(i);
}
});
return convertView;
}
@Override
public int getCount() {
return notifies.size();
}
@Override
public Object getItem(int position) {
return notifies.get(position);
}
@Override
public long getItemId(int position) {
return position;
