Android电话号码在活动中调用功能

Question

I am developing Android Application having ContactUs Page having Phone Number. I had given the Phone number in xml file as below:

<TextView 
android:layout_height="wrap_content" 
android:textAppearance="?android:attr/textAppearanceSmall" 
android:text="1-869-270-9099" 
android:textSize="11sp"
android:textColor="#104082"
android:textStyle="normal"
android:layout_width="wrap_content" 
android:id="@+id/textView4" 
android:layout_x="72dp" 
android:layout_y="160dp"/>

I had created the AlertDialog and when the phone number is clicked the alert dialog will be shown programatically as below:

   @Override
   protected Dialog onCreateDialog(int id) {
    switch (id) {
    case (R.id.textView4):

        Builder builder = new AlertDialog.Builder(this);
        builder.setMessage("Do you want to Call?");
        builder.setCancelable(false);
        builder.setPositiveButton("Call", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
               //Do Calling a Number


            }
        });
        builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
            public void onClick(DialogInterface dialog, int which) {
                    dialog.cancel();
            }
        });
        AlertDialog dialog = builder.create();
        dialog.show();
    }
    return super.onCreateDialog(id);
}
       public void onClick(View v) {

    switch(v.getId()){
    case (R.id.textView4):

        showDialog(R.id.textView4);
    break;
    }

}

Here my issue is to implement the "Calling a Phone Number" Function in the onClick "PositiveButton" method. Please help me how to get a DialPad with the number present in the xml file with the SampleCode/Links.

Answer 1

Maybe something like:

Intent call = new Intent(Intent.ACTION_DIAL);
call.setData(Uri.parse("tel:" + findViewByid(R.id.textView4).getText());
startActivity(call);

Answer 2

You can direclty launch a intent to get the dial pad with the number mentioned in your xml file.Like this:

String contact=findViewById(R.id.textView4).getText().toString();
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:" + contact));
startActivity(callIntent);

Answer 3

Inside the onClick of positive button just write:

Intent dial = new Intent();
dial.setAction("android.intent.action.DIAL");
dial.setData(Uri.parse("tel:"+dial_number));
startActivity(dial); 

Note: Don't forget to add this permission inside the AndroidManifest.xml file:

<uses-permission android:name="android.permission.CALL_PHONE"/>
