Android---01---打电话和发短信

1，打电话

在manifest文件中加入拨打权限

<uses-permission android:name="android.permission.CALL_PHONE" />

然后设置Intent 的Action 与 Data即可完成简单的拨打电话

package com.lc.call;import android.app.Activity;import android.content.Intent;import android.net.Uri;import android.os.Bundle;import android.view.Menu;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;public class MainActivity extends Activity {private Button callmemaybe=null;private EditText call=null;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);call=(EditText)findViewById(R.id.call);callmemaybe=(Button)findViewById(R.id.callmemaybe);callmemaybe.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {String number=call.getText().toString();Intent intent=new Intent();intent.setAction("android.intent.action.CALL");intent.setData(Uri.parse("tel:"+number));startActivity(intent);//方法内部会自动为Intent 添加类别， android.intent.category.DEFAULT}});}@Overridepublic boolean onCreateOptionsMenu(Menu menu) {// Inflate the menu; this adds items to the action bar if it is present.getMenuInflater().inflate(R.menu.activity_main, menu);return true;}}

2，发短信.

同理，加入发短信权限

<uses-permission  android:name="android.permission.SEND_SMS"/>"

这里要用到一个短信管理类SmsManager

package com.lc.sms;import java.util.ArrayList;import android.app.Activity;import android.os.Bundle;import android.telephony.gsm.SmsManager;import android.view.View;import android.view.View.OnClickListener;import android.widget.Button;import android.widget.EditText;import android.widget.Toast;public class MainActivity extends Activity {  private EditText smsnum;  private EditText smscontent;  private Button myButton;@Overrideprotected void onCreate(Bundle savedInstanceState) {super.onCreate(savedInstanceState);setContentView(R.layout.activity_main);smsnum=(EditText)findViewById(R.id.telephonenum);smscontent=(EditText)findViewById(R.id.smscontent);myButton=(Button)findViewById(R.id.myButton);myButton.setOnClickListener(new OnClickListener() {@Overridepublic void onClick(View arg0) {String num=smsnum.getText().toString();String content=smscontent.getText().toString();SmsManager sms=SmsManager.getDefault();//对内容进行分割放入数组 ArrayList<String>texts=sms.divideMessage(content); for(String text : texts ) {//params//1.发送到的地址，2.短信中心的地址,3.内容，4.发送状态，5.对方是否收到短信的状态sms.sendTextMessage(num, null, text, null, null); } Toast.makeText(MainActivity.this, "发送成功", Toast.LENGTH_LONG).show(); //smscontent.setText("");}});}}
