在清单文件中需要用到权限：
<uses-permission android:name="android.permission.CALL_PHONE"/>
获取到输入的号码后需要用intent 启动拨号器：
Intent intent=new Intent(Intent.ACTION_CALL,Uri.parse(("tel:"+infos)));
startActivity(intent);
以下全部代码：
package com.example.callphone;
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends Activity {
private EditText my_info;
private Button my_call;
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
init();
}
private void init() {
// TODO Auto-generated method stub
my_call = (Button) findViewById(R.id.call);
my_info = (EditText) findViewById(R.id.info);
my_call.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
// TODO Auto-generated method stub
String infos = my_info.getText().toString().trim();
Intent intent = new Intent(Intent.ACTION_CALL, Uri
.parse(("tel:" + infos)));
startActivity(intent);
}
});
}
}
xml布局代码：
<LinearLayout 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:orientation="vertical"
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.example.callphone.MainActivity" >
<EditText
android:id="@+id/info"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="请输入号码" />
<Button
android:id="@+id/call"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:hint="拨打" />
</LinearLayout>
