Phone Dialer App Learning

This thought is a simple telephone dialer, or learned a lot of things, so still learned a lot of things, understand the Android permissions Uri.parse several uses:

Not much to say on the code:

Package Com.djf.phone;import Android.app.activity;import Android.content.intent;import android.net.Uri;import Android.os.bundle;import Android.text.textutils;import Android.view.view;import Android.widget.EditText;import Android.widget.toast;public class Mainactivity extends Activity {@Overrideprotected void OnCreate (Bundle Savedinstancestate) {super.oncreate (savedinstancestate); Setcontentview (R.layout.activity_main);} public void Myclick (view view) {EditText Medittext = (EditText) Findviewbyid (R.id.et_number); String number = Medittext.gettext (). toString (). Trim (); Boolean result = Textutils.isempty (number); if (result) { Toast.maketext (This, "phone number is empty", 0). Show (); else {Intent Intent = new Intent (); intent.setaction (Intent.action_call);  Intent.setdata (Uri.parse ("Tel:" +number)); StartActivity (intent);}}}
