android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"

<!--

布局:wrap_content包裹
android:layout_width:宽

button_phone.setOnClickListener(new View.OnClickListener() {

@Override
public void onClick(View v) {
String phone_Num = edit_phone.getText().toString();

Intent intent = new Intent(Intent.ACTION_CALL,Uri.parse("tel:"+phone_Num));

PhoneActivity.this.startActivity(intent);

Toast.makeText(PhoneActivity.this, "正在给"+phone_Num+"拨打",Toast.LENGTH_LONG).show();
}
});

}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.phone, menu);
return true;
}

}
