how use two getIntent in activity?

how use two getIntent in activity? - android

I need to get data from two activity by get intent but is not work.
this activiy1:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long viewId) {
TextView idTextView = (TextView) view.findViewById(R.id.id);
TextView titleTextView = (TextView) view.findViewById(R.id.title);
TextView descTextView = (TextView) view.findViewById(R.id.desc);
String id = idTextView.getText().toString();
String title = titleTextView.getText().toString();
String desc = descTextView.getText().toString();
Intent modify_intent = new Intent(getApplicationContext(), ShowDat.class);
modify_intent.putExtra("title1", title);
modify_intent.putExtra("desc1", desc);
modify_intent.putExtra("id1", id);
startActivity(modify_intent);
}
});
and this activity2:
listView.setOnItemClickListener(new AdapterView.OnItemClickListener() {
#Override
public void onItemClick(AdapterView<?> parent, View view, int position, long viewId) {
TextView idTextView = (TextView) view.findViewById(R.id.id);
TextView titleTextView = (TextView) view.findViewById(R.id.title);
TextView descTextView = (TextView) view.findViewById(R.id.desc);
String id = idTextView.getText().toString();
String title = titleTextView.getText().toString();
String desc = descTextView.getText().toString();
Intent modify_intent = new Intent(getApplicationContext(), ShowDat.class);
modify_intent.putExtra("title2", title);
modify_intent.putExtra("desc2", desc);
modify_intent.putExtra("id2", id);
startActivity(modify_intent);
}
});
and this activity than receive data:
TextView idTextView = (TextView) findViewById(R.id.id);
TextView titleTextView = (TextView) findViewById(R.id.title);
TextView descTextView = (TextView) findViewById(R.id.desc);
Intent intent = getIntent();
if(intent != null) {
intent = getIntent();
String id = intent.getStringExtra("id1");
String name = intent.getStringExtra("title1");
String desc = intent.getStringExtra("desc1");
try {
_id = Long.parseLong(id);
} catch (NumberFormatException e) {
_id = 0; // your default value
}
idTextView.setText(id);
titleTextView.setText(name);
descTextView.setText(desc);
}
else {
intent = getIntent();
String id = intent.getStringExtra("id2");
String name = intent.getStringExtra("title2");
String desc = intent.getStringExtra("desc2");
try {
_id = Long.parseLong(id);
} catch (NumberFormatException e) {
_id = 0; // your default value
}
idTextView.setText(id);
titleTextView.setText(name);
descTextView.setText(desc);
}
i try to use this code but like above code, just on put extra receive and other not work:
TextView idTextView = (TextView) findViewById(R.id.id);
TextView titleTextView = (TextView) findViewById(R.id.title);
TextView descTextView = (TextView) findViewById(R.id.desc);
Intent intent = getIntent();
if(getIntent() !=null) {
String id = intent.getStringExtra("id1");
String name = intent.getStringExtra("title1");
String desc = intent.getStringExtra("desc1");
try {
_id = Long.parseLong(id);
} catch (NumberFormatException e) {
_id = 0; // your default value
}
idTextView.setText(id);
titleTextView.setText(name);
descTextView.setText(desc);
}
else {
String id = intent.getStringExtra("id2");
String name = intent.getStringExtra("title2");
String desc = intent.getStringExtra("desc2");
try {
_id = Long.parseLong(id);
} catch (NumberFormatException e) {
_id = 0; // your default value
}
idTextView.setText(id);
titleTextView.setText(name);
descTextView.setText(desc);
}
please help.

first you need to check like this
if(getIntent().hasExtra("key_1"))
{
String data = getIntent().getString("key_1");
}
else if(getIntent().hasExtra("key_2"))
{
String msg = getIntent().getString("key_2");
}
......

You can do that with two way.
1)if(getIntent().hasExtra("your_key")) and
2) use same key in two activities for passing data
like modify_intent.putExtra("same_key", title);

TextView update not happening when selected item from ListView

Hi I have Listview in that when I select an item I display another page where I am setting the text views with appropriate informations but when i select an item and go back and select another item the textviews are not getting updated ?BTW there are 10 text views can somebody provide me the solution for this?

String g = text.replace("{col5=", "");

String g3 = g2.replace(" col6=", "");
String g4 = g3.replace(" col1=", "");

String val[] = g7.split(",");
for (int m = 0; m < val.length; m++) {
Log.d("VALUE", val[m]);
ar1.add(val[m]);
}
System.out.println(ar1);
Log.d("VALUES-------->", text);
mob = ar1.get(0);
Log.d("VALUE1", mob);
pin = ar1.get(1);
Log.d("VALUE2", pin);

name = ar1.get(6);
Log.d("VALUE7", name);
lvo2 = ar1.get(7);
Log.d("VALUE8", lvo2);
}
});
}

From your code: ar1.add(val[m]);
I guess that ar1 is a List<String> variable of your listview activity?
If that's true, maybe add a call to clear() may work:
ar1.clear();
for(int m =0 ; m< val.length ; m++)
{
Log.d("VALUE",val[m]);
ar1.add(val[m]);
}

In Android how to prevent updating existing items on notifyDataSetChanged()

I have chat app
In custom array adapter. I set random colors to usernames for each message with this code:
String[] array = context.getResources().getStringArray(R.array.username_colors);
randomColor = array[new Random().nextInt(array.length)];
nameTextView.setTextColor(Color.parseColor(randomColor));
When new message arrive I add it to listview, and call adapter.notifyDataSetChanged();
This causes recoloring existing usernames in messages each time.
How can I prevent recoloring existing items in listview when calling adapter.notifyDataSetChanged();
Edit 1

You should keep color in the data class, for example in the Message class, or keep Map in the adapter, that maps Message to Color. Then randomly create a color, when it doesn't present in the map. or use the color, if it present in the map. Using a map is good solution than keeping in the data class, when the color doesn't related to message, when it is not a message property, so in that case, a good solution is a keeping it in the adapter class, in the map, for example
private Map<Message, String> colorsMap = new HashMap<Message, String>();
private void colorUsername(ViewHolder holder, Message message, String userName) {
String randomColor;
if(colorsMap.contains(message)) {
randomColor = colorsMap.get(message);
}
else {
if (userName.equals(USERNAME_ME)){
randomColor = "#000000";
}else if (message.getUserId()!=prevMsgUserID) {
do {
String[] array = context.getResources().getStringArray(R.array.username_colors);
randomColor = array[new Random().nextInt(array.length)];
}while (prevColor.equals(randomColor));
}
colorsMap.put(message, randomColor);
}
holder.nameTextView.setTextColor(Color.parseColor(randomColor));
}

Basically you have to create a Collection of user data model.
Like ArrayList<UserModel> arr = new ArrayList<UserModel>();
User Model can contain-> userId,userColor,groupId(if group chat supported) and map this model with you DB.
Means you have to make a column in db and add userBgColor in user table and map it with the model and this model in array list and supply the array list to your custom adapter .
Your can use ORMLite for rational mapping .
Then in getView()
{
UserModel model = arr.get(position);
String color = user.getUserColor();
}

Change two textViews inside a listview

Let's say, I have two textviews, TextView A and B.
when I click on A, I need to change both textviews;
When I click on B, I need it to do something else.
I used the setTag(key,A); and setTag(key,B); The textView A changed correctly but the textView B is null. And when I click on B it works.
Here is my code :

Use
View view = v.getParent();
and then try to initialize views with view in onClick
You can set Tag
h.name.setOnClickListener(listener);
h.name.setTag(h.numoflike); // use setTag only once
h.numoflike.setOnClickListener(listener);
h.numoflike.setTag(h.name); // use setTag only once
Then in on click
public void onClick(View v) {
switch(v.getId())
{
case R.id.CommentName :
TextView tv1 = (Button) v.getTag();
TextView tv2 = (TextView) v;
tv1.setText("clicked");
tv2.setText("clicked");
break;
case R.id.CommentNumOfLike :
//do something
break;
}
}
Or in onClick Initialize yours views
View view = v.getParent();
TextView tv = view.findVIewById(R.id.CommentName);
TextView tv1 = view.findVIewById(R.id.CommentNumOfLike);
tv.setText("clicked");
tv1.setText("clicked");

Calling url to open by text string

Ok so im making an app that involve a qr scanner on result i have text showing with the url of the code is there any way in an onclick listener to call the text from the result and open it in the browser if so how can I do it
Java Snippet
Button browser = (Button) findViewById(R.id.ulibutton);
browser.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
Intent i = new Intent(Intent.ACTION_VIEW, url = new URL(
getString(R.string.contents_text)));
startActivity(i);
}
});
ImageView barcodeImageView = (ImageView) findViewById(R.id.barcode_image_view);
if (barcode == null) {
barcodeImageView.setImageBitmap(BitmapFactory.decodeResource(
getResources(), R.drawable.icon));
} else {
barcodeImageView.setImageBitmap(barcode);
}
TextView formatTextView = (TextView) findViewById(R.id.format_text_view);
formatTextView.setText(rawResult.getBarcodeFormat().toString());
TextView typeTextView = (TextView) findViewById(R.id.type_text_view);
typeTextView.setText(resultHandler.getType().toString());
DateFormat formatter = DateFormat.getDateTimeInstance(DateFormat.SHORT,
DateFormat.SHORT);
String formattedTime = formatter.format(new Date(rawResult
.getTimestamp()));
TextView timeTextView = (TextView) findViewById(R.id.time_text_view);
timeTextView.setText(formattedTime);
TextView metaTextView = (TextView) findViewById(R.id.meta_text_view);
View metaTextViewLabel = findViewById(R.id.meta_text_view_label);
metaTextView.setVisibility(View.GONE);
metaTextViewLabel.setVisibility(View.GONE);
Map<ResultMetadataType, Object> metadata = rawResult
.getResultMetadata();
if (metadata != null) {
StringBuilder metadataText = new StringBuilder(20);
for (Map.Entry<ResultMetadataType, Object> entry : metadata
.entrySet()) {
if (DISPLAYABLE_METADATA_TYPES.contains(entry.getKey())) {
metadataText.append(entry.getValue()).append('\n');
}
}
if (metadataText.length() > 0) {
metadataText.setLength(metadataText.length() - 1);
metaTextView.setText(metadataText);
metaTextView.setVisibility(View.VISIBLE);
metaTextViewLabel.setVisibility(View.VISIBLE);
}
}
TextView contentsTextView = (TextView) findViewById(R.id.contents_text_view);
contentsTextView.setMovementMethod(LinkMovementMethod.getInstance());
CharSequence displayContents = resultHandler.getDisplayContents();
contentsTextView.setText(displayContents);
// Crudely scale betweeen 22 and 32 -- bigger font for shorter text
int scaledSize = Math.max(22, 32 - displayContents.length() / 4);
contentsTextView.setTextSize(TypedValue.COMPLEX_UNIT_SP, scaledSize);
}
}

Intent i = new Intent(Intent.ACTION_VIEW,Uri.parse(YourUrl)));
startActivity(i);

how use two getIntent in activity? - android

first you need to check like this if(getIntent().hasExtra("key_1")) { String data = getIntent().getString("key_1"); } else if(getIntent().hasExtra("key_2")) { String msg = getIntent().getString("key_2"); } ......

You can do that with two way. 1)if(getIntent().hasExtra("your_key")) and 2) use same key in two activities for passing data like modify_intent.putExtra("same_key", title);
