曾经的笔记——android的学习笔记(布局和电话、短信权限)

主要是练习布局——LinearLayout(线性布局)

 AbsoluteLayout 绝对布局  TableLayout表格布局  FrameLayout布局

================  拨号器   =====================

1、AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.peter.phone" android:versionCode="1" android:versionName="1.0" >
    <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="8" />
    <application android:allowBackup="true"  android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" android:theme="@style/AppTheme" >
        <activity android:name="com.peter.phone.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-permission android:name="android.permission.CALL_PHONE"/>
</manifest>

------------------------------------------------------------------------------------------------------------

2、activity_main.xml

LinearLayout的android:orientation="vertical"必不可少......

<?xml version="1.0" encoding="utf-8"?>
<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" tools:context=".MainActivity" >
  <TextView android:layout_width="match_parent" android:layout_height="wrap_content"
      android:text="@string/phone" />
  <EditText android:layout_width="match_parent" android:layout_height="wrap_content"
      android:id="@+id/phone_num"/>
  <Button android:layout_width="match_parent" android:layout_height="wrap_content"
      android:text="@string/dial_btn" android:id="@+id/dial_btn"/>
</LinearLayout>

---------------------------------------------------------------------------------------------------------------

3、MainActivity.java

public class MainActivity extends Activity {
 private EditText phone_num = null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button button = (Button)findViewById(R.id.dial_btn);
        /*button.setOnClickListener(new View.OnClickListener() {
   @Override
   public void onClick(View v) {
    phone_num = (EditText)findViewById(R.id.phone_num);
    Intent intent = new Intent(Intent.ACTION_CALL,
      Uri.parse("tel:"+phone_num.getText().toString()));
    startActivity(intent);
    //方法内部会自动为Intent添加类别：android.intent.category.DEFAULT    
   }
  });*/
        button.setOnClickListener(new ButtonOnClickListener());
    }
    /*@Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_main, menu);
        return true;
    }*/   
    public final class ButtonOnClickListener implements View.OnClickListener{
  @Override
  public void onClick(View v) {
   phone_num = (EditText)findViewById(R.id.phone_num);
   /*Intent intent = new Intent(Intent.ACTION_CALL,
    Uri.parse("tel:"+phone_num.getText().toString())); **/
   Intent intent = new Intent();
   intent.setAction(Intent.ACTION_CALL);
   intent.setData(Uri.parse("tel:"+phone_num.getText().toString()));
   startActivity(intent);
  }     
    }   
}

 

================  短信发送器   =====================

/AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.peter.sms" android:versionCode="1" android:versionName="1.0" >
    <uses-sdk android:minSdkVersion="8" android:targetSdkVersion="8" />
    <application
        android:allowBackup="true" android:icon="@drawable/ic_launcher"
        android:label="@string/app_name" android:theme="@style/AppTheme" >
        <activity android:name="com.peter.sms.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-permission android:name="android.permission.SEND_SMS"/>
</manifest>

-----------------------------------------------------------------------------------------------

2、activity_main.xml

 <?xml version="1.0" encoding="utf-8"?>
<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" tools:context=".MainActivity" >
  
    <RelativeLayout android:layout_width="fill_parent" android:layout_height="40dp">
     <TextView android:layout_width="wrap_content" android:id="@+id/numberlabel"
         android:layout_centerVertical="true"
         android:layout_height="wrap_content" android:text="@string/phone_num" />
     <EditText android:layout_width="match_parent"
         android:layout_height="wrap_content" android:id="@+id/phone_num"
          android:layout_toRightOf="@id/numberlabel"
          android:layout_centerVertical="true"
          android:layout_marginLeft="5dp"
         />
    </RelativeLayout>
    
    <TextView android:layout_width="match_parent"
        android:layout_height="wrap_content" android:text="@string/content" />
  <EditText android:layout_width="match_parent"
        android:layout_height="wrap_content" android:id="@+id/content"/>
  
  <Button android:layout_width="wrap_content" android:text="@string/sms_send"
        android:layout_height="wrap_content" android:id="@+id/button"  />
</LinearLayout>

3、MainActivity.java

public class MainActivity extends Activity {
 EditText phone_num = null;
 EditText content = null;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        Button button = (Button)findViewById(R.id.button);
        phone_num = (EditText)findViewById(R.id.phone_num);
        content = (EditText)findViewById(R.id.content);
        button.setOnClickListener(new ButtonOnClickListener());
    }

    public final class ButtonOnClickListener implements View.OnClickListener{
  @Override
public void onClick(View v) {
   String mobile = phone_num.getText().toString();
   String contentStr = content.getText().toString();
   PendingIntent pendingIntent = PendingIntent
     .getBroadcast(MainActivity.this, 0, new Intent(), 0);
   SmsManager manager = SmsManager.getDefault();
   ArrayList<String> texts = manager.divideMessage(contentStr);
   for(String text : texts){
    manager.sendTextMessage(mobile, null, text, pendingIntent, null);
   }
   Log.i("MainActivity", "mobile="+mobile+"; content="+contentStr);
   Toast.makeText(MainActivity.this,R.string.success,Toast.LENGTH_LONG).show();
  }    
    }
