问题描述
我正在尝试拨打应用程序中的电话
，我希望它在通话后返回应用程序
我在这个论坛上问了这个问题，但我不明白答案
public void call（）{
尝试{
Intent callIntent = new Intent（Intent.ACTION_CALL）;
callIntent.setData（Uri.parse（tel：048598077））;
getContext（）。startActivity（callIntent）;
} catch（ActivityNotFoundException activityException）{
Log.e（dialing-example，Call failed，activityException）;}
finally {
EndCallListener callListener = new EndCallListener（）;
TelephonyManager mTM =（TelephonyManager）getContext（）。getSystemService（Context.TELEPHONY_SERVICE）;
mTM.listen（callListener，PhoneStateListener.LISTEN_CALL_STATE）;
$ b Private class EndCallListener扩展PhoneStateListener {
@Override
public void onCallStateChanged（int state，String incomingNumber）{
if（TelephonyManager.CALL_STATE_RINGING == state）{
Log.i（LOG_TAG，RINGING，number：+ incomingNumber）;
if（TelephonyManager.CALL_STATE_OFFHOOK ==状态）{
//等待电话摘机（可能设置一个布尔标志），以便知道您的应用发起了呼叫。
Log.i（LOG_TAG，OFFHOOK）;
if（TelephonyManager.CALL_STATE_IDLE == state）{
//当这种状态发生，并且你的标志被设置时，重新启动你的应用程序
Log.i（LOG_TAG，闲）;
$ / code $ / pre
我知道这样的事情，但我没有' t在任何时候开始 CallListener 。
所以我该怎么做？解决方案好的，我找到了答案
这里是代码：
import android.app.Activity;
导入android.content.Context;
导入android.content.Intent;
导入android.net.Uri;
导入android.os.Bundle;
导入android.telephony.PhoneStateListener;
导入android.telephony.TelephonyManager;
导入android.util.Log;
导入android.view.View;
导入android.view.View.OnClickListener;
导入android.widget.Button;
public class MainActivity extends Activity {
final Context context = this;
私人按钮按钮;
public void onCreate（Bundle savedInstanceState）{
super.onCreate（savedInstanceState）;
setContentView（R.layout.main）;
button =（Button）findViewById（R.id.buttonCall）;
//添加PhoneStateListener
//添加按钮侦听器
button.setOnClickListener（new OnClickListener（）{
@Override
public void onClick（View arg0）{
call（）;
}
}）;
private void call（）
{
PhoneCallListener phoneListener = new PhoneCallListener（）;
TelephonyManager telephonyManager =（TelephonyManager）this
.getSystemService（Context.TELEPHONY_SERVICE）;
telephonyManager.listen（phoneListener，
PhoneStateListener.LISTEN_CALL_STATE）;
Intent callIntent = new Intent（Intent.ACTION_CALL）;
callIntent.setData（Uri.parse（tel：0377778888））;
startActivity（callIntent）;
}
私人类PhoneCallListener扩展PhoneStateListener {
private boolean isPhoneCalling = false;
字符串LOG_TAG =LOGGING 123;
@Override
public void onCallStateChanged（int state，String incomingNumber）{
if（TelephonyManager.CALL_STATE_RINGING == state）{
// phone响铃
Log.i（LOG_TAG，RINGING，number：+ incomingNumber）; （TelephonyManager.CALL_STATE_OFFHOOK ==状态）{
//活动
Log.i（LOG_TAG，OFFHOOK）;
}
if
isPhoneCalling = true;
}
if（TelephonyManager.CALL_STATE_IDLE == state）{
//在类初始化和电话结束时运行，需要检测标志
//从CALL_STATE_OFFHOOK
Log.i（LOG_TAG，IDLE）;
if（isPhoneCalling）{
Log.i（LOG_TAG，restart app）;
//重新启动应用程序
意图i = getBaseContext（）。getPackageManager（）
.getLaunchIntentForPackage（
getBaseContext（）。getPackageName（））;
i.addFlags（Intent.FLAG_ACTIVITY_CLEAR_TOP）;
startActivity（i）;
isPhoneCalling = false;
}
}
}
}
}
，并且在制造商中我们需要添加
< uses-permission android：name = android.permission.CALL_PHONE/>
<使用权限android：name =android.permission.READ_PHONE_STATE/>
i'm trying to make a phone call from the app
and I want it to return back to the app after the call
i asked that question in this forum but i didn't understand the answer
How to make a phone call in android and come back to my activity when the call is done?
public void call() {
try {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:048598077"));
getContext().startActivity(callIntent);
} catch (ActivityNotFoundException activityException) {
Log.e("dialing-example", "Call failed", activityException);}
finally {
EndCallListener callListener = new EndCallListener();
TelephonyManager mTM = (TelephonyManager)getContext().getSystemService(Context.TELEPHONY_SERVICE);
mTM.listen(callListener, PhoneStateListener.LISTEN_CALL_STATE);
}
}
private class EndCallListener extends PhoneStateListener {
@Override
public void onCallStateChanged(int state, String incomingNumber) {
if(TelephonyManager.CALL_STATE_RINGING == state) {
Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
}
if(TelephonyManager.CALL_STATE_OFFHOOK == state) {
//wait for phone to go offhook (probably set a boolean flag) so you know your app initiated the call.
Log.i(LOG_TAG, "OFFHOOK");
}
if(TelephonyManager.CALL_STATE_IDLE == state) {
//when this state occurs, and your flag is set, restart your app
Log.i(LOG_TAG, "IDLE");
}
}
i understand some thing like that, but i didn't start the CallListener at any point.
So how can i do that ?
解决方案 ok , I found the answer
here is the code :
import android.app.Activity;
import android.content.Context;
import android.content.Intent;
import android.net.Uri;
import android.os.Bundle;
import android.telephony.PhoneStateListener;
import android.telephony.TelephonyManager;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
public class MainActivity extends Activity {
final Context context = this;
private Button button;
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
button = (Button) findViewById(R.id.buttonCall);
// add PhoneStateListener
// add button listener
button.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View arg0) {
call();
}
});
}
private void call()
{
PhoneCallListener phoneListener = new PhoneCallListener();
TelephonyManager telephonyManager = (TelephonyManager) this
.getSystemService(Context.TELEPHONY_SERVICE);
telephonyManager.listen(phoneListener,
PhoneStateListener.LISTEN_CALL_STATE);
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:0377778888"));
startActivity(callIntent);
}
private class PhoneCallListener extends PhoneStateListener {
private boolean isPhoneCalling = false;
String LOG_TAG = "LOGGING 123";
@Override
public void onCallStateChanged(int state, String incomingNumber) {
if (TelephonyManager.CALL_STATE_RINGING == state) {
// phone ringing
Log.i(LOG_TAG, "RINGING, number: " + incomingNumber);
}
if (TelephonyManager.CALL_STATE_OFFHOOK == state) {
// active
Log.i(LOG_TAG, "OFFHOOK");
isPhoneCalling = true;
}
if (TelephonyManager.CALL_STATE_IDLE == state) {
// run when class initial and phone call ended, need detect flag
// from CALL_STATE_OFFHOOK
Log.i(LOG_TAG, "IDLE");
if (isPhoneCalling) {
Log.i(LOG_TAG, "restart app");
// restart app
Intent i = getBaseContext().getPackageManager()
.getLaunchIntentForPackage(
getBaseContext().getPackageName());
i.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(i);
isPhoneCalling = false;
}
}
}
}
}
and in the manufest we need to add
<uses-permission android:name="android.permission.CALL_PHONE" />
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
