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"

??
??<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.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();
??}????
??? }
