android 4.x版本如何实现电话拨打功能

xkjywan 2014-05-15 01:50:22

4.x版本新加入了frogment的类，我在frogment_main.xml中添加控件，希望实现输入电话号码后点击按钮后自动拨号的功能

frogment_main.xml----

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:paddingBottom="@dimen/activity_vertical_margin"
android:paddingLeft="@dimen/activity_horizontal_margin"
android:paddingRight="@dimen/activity_horizontal_margin"
android:paddingTop="@dimen/activity_vertical_margin"
tools:context="com.xk.example.phone.MainActivity$PlaceholderFragment" >

<TextView
android:id="@+id/text1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/tip" />
<EditText
android:id="@+id/edittext"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:inputType="number|phone"
android:layout_below="@+id/text1"
/>

<Button
android:id="@+id/button1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/edittext"
android:text="@string/button1" />

</RelativeLayout>

src/MainActivity.java加入一个按钮监听------

public static class PlaceholderFragment extends Fragment {

public PlaceholderFragment() {
}

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
final View rootView = inflater.inflate(R.layout.fragment_main, container,
false);

Button mbutton = (Button)rootView.findViewById(R.id.button1);
mbutton.setOnClickListener(new CallTel());

return rootView;
}
}

新建CallTell的类该怎么写呢，
完成一部分，但是不知道怎么启动。麻烦大师看看

import android.content.Intent;
import android.net.Uri;
import android.sax.StartElementListener;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.EditText;

public class CallTel implements OnClickListener {

private View rootView;

@Override
public void onClick(View arg0) {
EditText mobileText = (EditText)rootView.findViewById(R.id.edittext);
String number = mobileText.getText().toString();
Intent intent = new Intent();
intent.setAction("android.intent.action.CALL");
intent.addCategory("android.intent.category.DEFAULT");
intent.setData(Uri.parse("tel" + number));

}

}
