android学习系列-短信发送器与电话拨号器调用(3)
一.短信发送器
1)步骤:(1)输入号码(2)输入短信内容(3)点击发送按钮发送短信。
2)注意事项,短信内容太长时,分多条发送。发送完毕提示。
3)后台代码
import java.util.ArrayList;
import android.app.Activity;
import android.os.Bundle;
import android.telephony.SmsManager;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
import android.widget.Toast;
public class MainActivity extends Activity {
private EditText numberText;
private EditText contentText;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
numberText = (EditText) this.findViewById(R.id.number);
contentText = (EditText) this.findViewById(R.id.content);
Button button = (Button) this.findViewById(R.id.button);
button.setOnClickListener(new ButtonClickListener());//点击发送按钮
}
private final class ButtonClickListener implements View.OnClickListener{
public void onClick(View v) {
String number = numberText.getText().toString();//手机号码
String content = contentText.getText().toString();//短信内容
SmsManager manager = SmsManager.getDefault();//获得短信发送器
ArrayList<String> texts = manager.divideMessage(content);//短信太长时分割短信
for(String text : texts){
manager.sendTextMessage(number, null, text, null, null);//分成多条发送
}
Toast.makeText(MainActivity.this, R.string.success, Toast.LENGTH_LONG).show();//发送成功吐司提示。
}
}
}
4)前台代码
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<TextView
android:layout_width="100dp"
android:layout_height="wrap_content"
android:text="@string/number"
android:id="@+id/numberlabel"
/>
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/number"
android:layout_toRightOf="@id/numberlabel"
android:layout_alignTop="@id/numberlabel"
android:layout_marginLeft="5dp"
/>
</RelativeLayout>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/content"
/>
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minLines="3"
android:id="@+id/content"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button"
android:id="@+id/button"
/>
</LinearLayout>
5)注意AndroidManifest.xml文件中加入发送短信功能权限配置
<uses-permission android:name="android.permission.SEND_SMS"/>
二,电话拨号器
1)后台代码
import android.app.Activity;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.view.View;
import android.widget.Button;
import android.widget.EditText;
public class MainActivity extends Activity {
private EditText mobileText;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
mobileText = (EditText) findViewById(R.id.mobile);
Button button = (Button) this.findViewById(R.id.button);
button.setOnClickListener(new ButtonClickListener());
}
private final class ButtonClickListener implements View.OnClickListener{
public void onClick(View v) {
String number = mobileText.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
}
}
}
2)前台代码
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
>
<RelativeLayout
android:layout_width="fill_parent"
android:layout_height="wrap_content"
>
<TextView
android:layout_width="100dp"
android:layout_height="wrap_content"
android:text="@string/number"
android:id="@+id/numberlabel"
/>
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:id="@+id/number"
android:layout_toRightOf="@id/numberlabel"
android:layout_alignTop="@id/numberlabel"
android:layout_marginLeft="5dp"
/>
</RelativeLayout>
<TextView
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:text="@string/content"
/>
<EditText
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:minLines="3"
android:id="@+id/content"
/>
<Button
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/button"
android:id="@+id/button"
/>
</LinearLayout>
3)注意AndroidManifest.xml中配置权限
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="cn.itcast.phone"
android:versionCode="1"
android:versionName="1.0">
<application android:icon="@drawable/icon" android:label="@string/app_name">
<activity android:name=".MainActivity"
android:label="@string/app_name">
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
</application>
<uses-sdk android:minSdkVersion="8" />
<--配置权限-->
<uses-permission android:name="android.permission.CALL_PHONE"/>
</manifest>
