1.首先添加 Android Layout 文件
File : res/layout/main.xml
class="xml" name="code">
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:orientation="vertical" >
<Button android:id="@+id/call_button"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:text="@string/call_button"/>
</LinearLayout>
2. Activity
其核心代码
Intent mIntent = new Intent(Intent.ACTION_CALL);
mIntent.setData(Uri.parse("tel:02133330000"));
startActivity(mIntent);
完整代码MainActivity.java
package com.lance.app;
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.widget.Button;
public class MainActivity extends Activity {
private Button mCallButton;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
//call button Listener
addCallButtonListener();
}
/**
* call button Listener
*/
private void addCallButtonListener() {
mCallButton = (Button)findViewById(R.id.call_button);
mCallButton.setOnClickListener(new View.OnClickListener() {
public void onClick(View v) {
Intent mIntent = new Intent(Intent.ACTION_CALL);
mIntent.setData(Uri.parse("tel:02133330000"));
startActivity(mIntent);
}
});
}
@Override
public boolean onCreateOptionsMenu(Menu menu) {
getMenuInflater().inflate(R.menu.main, menu);
return true;
}
}
3.Android Manifest
添加权限
<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
package="com.lance.app"
android:versionCode="1"
android:versionName="1.0" >
<uses-sdk
android:minSdkVersion="8"
android:targetSdkVersion="18" />
<!-- 加入访问权限 -->
<uses-permission android:name="android.permission.CALL_PHONE"/>
<!-- 否则不能监听每个状态 -->
<uses-permission android:name="android.permission.READ_PHONE_STATE"/>
<application
android:allowBackup="true"
android:icon="@drawable/ic_launcher"
android:label="@string/app_name"
android:theme="@style/AppTheme" >
<activity
android:name="com.lance.app.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>
</manifest>
4.增加PhoneStateListener监听
//add call state listener
TelephonyManager telephonyManager = (TelephonyManager)getSystemService(MainActivity.TELEPHONY_SERVICE);
PhoneCallListener phoneCallListener = new PhoneCallListener();
telephonyManager.listen(phoneCallListener,PhoneStateListener.LISTEN_CALL_STATE);
MainActivity内部类
/**
* 监听状态, 重启app
* @author lance
*/
private class PhoneCallListener extends PhoneStateListener {
private final String LOG_TAG = "com.lance.app.PhoneCallListener";
private boolean isPhoneCalling = false;
public void onCallStateChanged(int state, String incomingNumber) {
if(TelephonyManager.CALL_STATE_RINGING == state) {
Log.i(LOG_TAG, "正在呼叫: "+incomingNumber);
}
if(TelephonyManager.CALL_STATE_OFFHOOK == state) {
Log.i(LOG_TAG, "OFFHOOK");
isPhoneCalling = true;
}
if(TelephonyManager.CALL_STATE_IDLE == state) {
Log.i(LOG_TAG, "Idle");
if(isPhoneCalling) {
Log.i(LOG_TAG, "restart app");
Intent intent = getBaseContext()
.getPackageManager()
.getLaunchIntentForPackage(getBaseContext().getPackageName())
.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(intent);
isPhoneCalling = false;
}
}
}
}
