This is mainly to realize the mobile phone communication, which mainly realizes the function of making calls and sending short messages.
The dialing interface is as follows (due to the compatibility problem of the emulator screen, the interface cannot be displayed normally, but it can be displayed normally on the mobile phone):
When each number is clicked, the imagebutton will change the image, as follows:
To achieve this function, the main thing is to monitor the imagebutton. The code is as follows:
imageButton1.setOnTouchListener(new View.OnTouchListener(){
public boolean onTouch(View v, MotionEvent event) {
//click
if(event.getAction() == MotionEvent.ACTION_DOWN){
//reset the background image when pressed
((ImageButton)v).setImageDrawable(getResources().getDrawable(R.drawable.d1));
}else if(event.getAction() == MotionEvent.ACTION_UP){ //松开
//Modify to the normal picture when lifted
((ImageButton)v).setImageDrawable(getResources().getDrawable(R.drawable.d1));
}
return false;
}
});
The code to implement the dialing function is as follows, and ACTION_CALL needs to be called:
public void dial(View view) {
EditText text=(EditText)findViewById(R.id.editText1);
String number=text.getText().toString();
Intent intent = new Intent();
intent.setAction(intent.ACTION_CALL);
intent.setData(Uri.parse("tel:"+number));
startActivity(intent);//The method will automatically add a category to the Intent: android.intent.category.DEFAULT
}

SMS function (the renderings are as follows):
The main code to implement this function is:
public void send(View view){
String telMsg=MainActivity.this.tel.getText().toString();
String contentMsg=MainActivity.this.content.getText().toString();
Uri uri=Uri.parse("smsto:"+telMsg);//Receiver's mobile phone
Intent it=new Intent();
it.setAction(Intent.ACTION_SENDTO);//Specify action, I want to send text message
it.putExtra("sms_body", contentMsg);//Set the information content
it.setType("vnd.android-dir/mms-sms");//Set MIME type
it.setData(uri);//Set data, where to go
MainActivity.this.startActivity(it);
}

</item>
</layer-list>
Correspondingly, it should also be noted that the corresponding permissions must be set:
