How do I make a phone call when I get number from edittext? I try this but it does not work. I have a problem with passing variable number to Uri.parse() must be inside void the gettext?
public String string;
public String number;
#Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
EditText txtcallnumber;
txtcallnumber = (EditText)findViewById(R.id.callnumber);
string = txtcallnumber.getText().toString().trim();//There no work call
number = "tel:" + string;
Button button = (Button) findViewById(R.id.button1);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
call();
}
});
}
public void call() {
try {
Intent callIntent = new Intent(Intent.ACTION_CALL);
//callIntent.setData(Uri.parse("tel:xxxxxxx")); //This work
string = txtcallnumber.getText().toString().trim();
number = "tel:" + string;//There work call
callIntent.setData(Uri.parse(number));
startActivity(callIntent);
} catch (ActivityNotFoundException activityException) {
Log.e("helloandroid dialing example", "Call failed");
}
You need to add Permission inside in your manifest file ::
<uses-permission android:name="android.permission.CALL_PHONE">
Inside your call() method try to use these Intent::
number=edittext.getText().trim();
no="tel:"+number;
startActivity(new Intent(Intent.ACTION_CALL, Uri.parse(no)));
in onCreate method there is no need for :
string = txtcallnumber.getText().toString().trim();
number = "tel:" + string;
because onCreate is pretty much used for setting up the display and there will be no input by the user before the screen is set up but in onCall method after entering the text and pressing the button then it wouldd...you know.
Plus you should have this to check for nothing entered:
if(string!=null){
try{try {
Intent callIntent = new Intent(Intent.ACTION_CALL);
string = txtcallnumber.getText().toString().trim();
number = "tel:" + string;
startActivity(new Intent(Intent.ACTION_CALL, Uri.parse(number)));
} catch (ActivityNotFoundException activityException) {
Log.e("helloandroid dialing example", "Call failed");
}}else{
Log.d("helloandroid dialing example","nothing entered");}

I would like to set my own activity infront the call screen. I have seen that there are many examples for this but with the older versions of android, while I want it to work with android 6.0 and above. This means that I have to deal with the permissions. I managed to grant the necessary permissions. After that I make a Class that inherits BroadcastReceiver so that I can detect when the phone is ringing, the only problem is that I can't send my activity infront of the call display. These are some of the classes I use:
public class PhoneStateReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
try {
System.out.println("Receiver start");
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
Toast.makeText(context, " Receiver start ", Toast.LENGTH_SHORT).show();
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
Toast.makeText(context, "Ringing State Number is -", Toast.LENGTH_SHORT).show();
Intent dialogIntent = new Intent(context, LockActivity.class);
dialogIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
context.startActivity(dialogIntent);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
public class LockActivity extends AppCompatActivity {
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_lock_screen);
getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON
+ WindowManager.LayoutParams.FLAG_DISMISS_KEYGUARD |
+WindowManager.LayoutParams.FLAG_SHOW_WHEN_LOCKED |
+WindowManager.LayoutParams.FLAG_TURN_SCREEN_ON);
Button btnLock = (Button) findViewById(R.id.btnUnlock);
final EditText txtPass = (EditText) findViewById(R.id.txtPass);
btnLock.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
String pass = txtPass.getText().toString();
if(pass.equals("pass")||pass.equals("пасс")) {
finish();
}else{
Toast.makeText(LockActivity.this, "Wrong password!", Toast.LENGTH_SHORT).show();
}
}
});
}
}
If anything else is needed please ask!
I managed to solve it, the problem is that it takes time to start the in-built call activity, so my activity started first and the other went on top of it. Therefore I made the current thread of my activity to sleep for less than a second. The in-built activity was launched and then my activity went on top of it.
public class PhoneStateReceiver extends BroadcastReceiver {
public void onReceive(Context context, Intent intent) {
try {
System.out.println("Receiver start");
String state = intent.getStringExtra(TelephonyManager.EXTRA_STATE);
Toast.makeText(context, " Receiver start ", Toast.LENGTH_SHORT).show();
if (state.equals(TelephonyManager.EXTRA_STATE_RINGING)) {
Toast.makeText(context, "Ringing State Number is -", Toast.LENGTH_SHORT).show();
Intent dialogIntent = new Intent(context, LockActivity.class);
dialogIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK|Intent.FLAG_ACTIVITY_REORDER_TO_FRONT);
Thread.sleep(700);
context.startActivity(dialogIntent);
}
} catch (Exception e) {
e.printStackTrace();
}
}
}
How do I call a number ending with '#' sign using android dialer?
My code is as follows,
EditText firstNumber;
Button btnAdd;
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main23);
Toast.makeText(Main23Activity.this,
"Type in your Pin Number", Toast.LENGTH_LONG).show();
btnAdd = (Button)findViewById(R.id.button12);
btnAdd.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
try {
numberSign = "#";
EditText et = (EditText) findViewById(R.id.editText6);
String text= et.getEditableText().toString();
Toast.makeText(Main23Activity.this,
"Adding Money to your account has never been this easy", Toast.LENGTH_LONG).show();
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:*221*" + text + numberSign ));
startActivity(intent);
} catch (Exception e) {
}
}
});
}
}
This is how you call a number ending with '#' using android dialer. You need to encode and then parse.
Try the below code,
String text = et.getText().toString();
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.parse("tel:" + Uri.encode("*221*" + text + "#")));
startActivity(intent);
Using this link you can get unicode and hex values
for example 36 can be stored in strings.xml as
<string name="abcd">36</string>
Below is the code that i used to open an app on the google paly.
final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (Exception e) {
Log.d(tag,"Message ="+e);
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + appPackageName)));
}
I have provided the hyperlink at the last of the text of the textview.how i can open an app on the google paly when user click on the hyperlink.
Use the below code in xml
<TextView
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="<market_url>"
android:id="#+id/openPlaystore"
android:autoLink="all"
android:linksClickable="true">
</TextView>
OR
Add OnClickListener to the textview
TextView tv = (TextView)findViewById(R.id.openPlaystore);
tv.setOnClickListener(new OnClickListener() {
#Override
public void onClick(View v) {
final String appPackageName = getPackageName(); // getPackageName() from Context or Activity object
try {
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
} catch (Exception e) {
Log.d(tag,"Message ="+e);
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=" + appPackageName)));
}
}
});
I have an app where I do the same... I use this code:
tv.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v)
{
TextView tv = (TextView)v;
if(! (tv.getSelectionStart()==-1 && tv.getSelectionEnd()==-1))
// Fired only when you touch the part of the text that is hyperlinked
// do something
}
Note that this works ONLY if you already successfully have your TextView display the hyperlink. Also, you usually don't need any code, since a hyperlink is resolved automatically by the TextView, but this code allows you to do additional processing.
I'm developing an app which will do multiple method in a single input. For example calculating square circumference and area, I give only one EditText and two button. But when I run the app, if I give an input and click the area button it won't do the calculation until I click the circumference button. And same goes if I change the input. Here is the code:
#Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.square);
etSide = (EditText) findViewById(R.id.etSquare);
tvResult = (TextView) findViewById(R.id.tvSquare);
Button btnCir = (Button) findViewById(R.id.btnSqrCir);
btnCir.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
countCir();
}
});
Button btnArea = (Button) findViewById(R.id.btnSqrArea);
btnArea.setOnClickListener(new View.OnClickListener(){
#Override
public void onClick(View v) {
countArea();
}
});
}
private void countArea() {
try {
side = etSide.getText().toString();
s = parseInt(side);
area = s * s;
tvResult.setText("Area = " + cir);
} catch (NumberFormatException ex){
Toast.makeText(getApplicationContext(), "Oops, you seem haven't enter the side length", Toast.LENGTH_LONG).show();
}
}
private void countCir() {
try {
side = etSide.getText().toString();
s = parseInt(side);
cir = 4 * s;
tvResult.setText("Circumference = " + area);
} catch (NumberFormatException ex){
Toast.makeText(getApplicationContext(), "Oops, you seem haven't enter the side length", Toast.LENGTH_LONG).show();
}
}
Any better idea? Really need help...
It looks like you have your variables backwards. For example:
private void countArea() {
try {
side = etSide.getText().toString();
s = parseInt(side);
area = s * s;
tvResult.setText("Area = " + cir); // <-- here cir doesn't have a value until you click the circumference button
} catch (NumberFormatException ex){
Toast.makeText(getApplicationContext(), "Oops, you seem haven't enter the side length", Toast.LENGTH_LONG).show();
}
}
So your TextView would display ""Area = ""
It looks to me like you want
tvResult.setText("Area = " + cir);
to be
tvResult.setText("Area = " + area);
Let me know if I'm not understanding you correctly
Note:
For your Toast you should use this or YourActivityName.this for Context instead of getApplicationContext()
One other suggestion I might make since your onClick()s only call a method, to make it simpler you could use one listener like this
public void onCreate(...)
{
...
btnCir.setOnClickListener(this);
btnArea.setOnClickListener(this);
...
}
public void onClick(View v)
{
switch(v.getId()) // get the id of the Button clicked
{
case (R.id.btnSqrArea): // call appropriate method
countArea();
break;
case (R.id.btnSqrCir):
countCir();
break;
}
}
You would just have to remember to add implements OnClickListener to your class definition. That's just a preference but worth mentioning.
I'm trying to send a USSD code through my cellphone, so I used an intent as many here suggested is the way to send the code. Unfortunately, every time I send the code it sends the same number *4355696753
the code I'm using to send the USSD is:
sendCode.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String cUssd = ussdCodeEdTxt.getText().toString();
String cToSend = "tel:*" + cUssd + Uri.encode("#");
startActivityForResult(new Intent("android.intent.action.CALL",
Uri.parse(cToSend)), 1);
}
});
any ideas would be greatly appreciated
I think you may need to use Uri.encode("*") for the star as well
sendCode.setOnClickListener(new View.OnClickListener() {
#Override
public void onClick(View v) {
// TODO Auto-generated method stub
String cUssd = ussdCodeEdTxt.getText().toString();
String cToSend = "tel:" + Uri.encode("*") + cUssd + Uri.encode("#");
startActivityForResult(new Intent("android.intent.action.CALL",
Uri.parse(cToSend)), 1);
}
});
though this is an old post but, for those facing the same issue try this Uri.fromParts("tel", number eg = *222# , "#");
