android sdk --- dial的用例

需求：

在editText中输入号码，点击button，自动拨号

代码：

public class MainActivity extends Activity {

 private Button mButton;
 private EditText mEditText;
 
 protected void onCreate(Bundle savedInstanceState) {
  super.onCreate(savedInstanceState);
  setContentView(R.layout.activity_main);
  
  mButton = (Button)findViewById(R.id.button1);
  mEditText = (EditText)findViewById(R.id.editText1);
  
  mButton.setOnClickListener(new Button.OnClickListener()
  {

   @Override
   public void onClick(View arg0) {
    // TODO Auto-generated method stub
    try
    {
     String strInput = mEditText.getText().toString();
     if(1 == 1)
     {
      Intent myIntentDial = new
        Intent("android.intent.action.CALL", Uri.parse("tel:"+strInput));
      startActivity(myIntentDial);
      mEditText.setText("");
      
     }
     else
     {
      mEditText.setText("");
      Toast.makeText(MainActivity.this, "input num:", Toast.LENGTH_LONG).show();
     }
    }
    catch(Exception e)
    {
     e.printStackTrace();
    }
   }
   
  });
 }

 @Override
 public boolean onCreateOptionsMenu(Menu menu) {
  // Inflate the menu; this adds items to the action bar if it is present.
  getMenuInflater().inflate(R.menu.main, menu);
  return true;
 }

}

AndroidManifest.xml中

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.example.calltest"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="18" />

    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name="com.example.calltest.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>

<!--拨号权限>
  <uses-permission android:name="android.permission.CALL_PHONE">
      </uses-permission>
</manifest>

 

重点：

1.添加拨号权限；

2.启动另一个活动的方式；

3.如何设置为拨号
