如何在Android中使用intent打电话？

Question

我正在使用以下代码在Android中进行调用,但它给了我安全例外,请帮忙.

 posted_by = "111-333-222-4";

 String uri = "tel:" + posted_by.trim() ;
 Intent intent = new Intent(Intent.ACTION_CALL);
 intent.setData(Uri.parse(uri));
 startActivity(intent);

权限

 <uses-permission android:name="android.permission.CALL_PHONE" />

例外

Answer 1

你可以用Intent.ACTION_DIAL而不是Intent.ACTION_CALL.这会显示已输入号码的拨号器,但允许用户决定是否实际拨打电话.ACTION_DIAL不需要CALL_PHONE许可.

Answer 2

这个演示对你有帮助......

通话按钮单击:

Intent intent = new Intent(Intent.ACTION_CALL, Uri.parse("tel:" + "Your Phone_number"));
startActivity(intent);

清单许可:

 <uses-permission android:name="android.permission.CALL_PHONE" />

Answer 3

更优雅的选择:

String phone = "+34666777888";
Intent intent = new Intent(Intent.ACTION_DIAL, Uri.fromParts("tel", phone, null));
startActivity(intent);

Answer 4

一切都好.

我刚在清单文件中的应用程序标记之前放置了调用权限标记

现在每件事情都很好.

Answer 5

在您的意图中使用ACTION_DIAL操作,这样您就不需要任何权限.您需要ACTION_CALL权限的原因是在没有用户任何操作的情况下拨打电话.

Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:0987654321"));
startActivity(intent);

Answer 6

重要的提示:

如果您使用Intent.ACTION_CALL,则必须添加CALL_PHONE权限.

只有当你不希望你的应用程序在谷歌播放中显示没有使用SIM卡或没有GSM的平板电脑时,它才有用.

在你的活动中:

            Intent callIntent = new Intent(Intent.ACTION_CALL);
            callIntent.setData(Uri.parse("tel:" + Constants.CALL_CENTER_NUMBER));
            startActivity(callIntent);

表现:

<uses-permission android:name="android.permission.CALL_PHONE" />

因此,如果它不是您应用的关键功能,请尽量远离添加CALL_PHONE权限.

其他解决方案

是显示电话应用程序的屏幕上写的数字,因此用户只需要点击通话按钮:

            Intent dialIntent = new Intent(Intent.ACTION_DIAL);
            dialIntent.setData(Uri.parse("tel:" + Constants.CALL_CENTER_NUMBER));
            startActivity(dialIntent);

不需要许可.

Answer 7

只需简单的oneliner,无需任何额外的权限:

private void dialContactPhone(final String phoneNumber) {
    startActivity(new Intent(Intent.ACTION_DIAL, Uri.fromParts("tel", phoneNumber, null)));
}

Answer 8

使用此完整代码

          Intent callIntent = new Intent(Intent.ACTION_DIAL);
          callIntent.setData(Uri.parse("tel:"+Uri.encode(PhoneNum.trim())));
          callIntent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
          startActivity(callIntent);     

Answer 9

请求清单中的权限

<uses-permission android:name="android.permission.CALL_PHONE" />

用于调用使用此代码

Intent in = new Intent(Intent.ACTION_CALL, Uri.parse("tel:99xxxxxxxx"));
try {
    startActivity(in);
} catch (android.content.ActivityNotFoundException ex) {
    Toast.makeText(mcontext, "Could not find an activity to place the call.", Toast.LENGTH_SHORT).show();
}

Answer 10

// Java
String mobileNumber = "99XXXXXXXX";
Intent intent = new Intent();
intent.setAction(Intent.ACTION_DIAL); // Action for what intent called for
intent.setData(Uri.parse("tel: " + mobileNumber)); // Data with intent respective action on intent
startActivity(intent);

// Kotlin
val mobileNumber = "99XXXXXXXX"
val intent = Intent()
intent.action = Intent.ACTION_DIAL // Action for what intent called for
intent.data = Uri.parse("tel: $mobileNumber") // Data with intent respective action on intent
startActivity(intent)

Answer 11

权限:

<uses-permission android:name="android.permission.CALL_PHONE" />

意图:

Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:0377778888"));
startActivity(callIntent);

Answer 12

你也可以使用它:

String uri = "tel:" + posted_by.replaceAll("[^0-9|\\+]", "");

Answer 13

AndroidManifest.xml中的权限

<uses-permission android:name="android.permission.CALL_PHONE" />

完整代码:

private void onCallBtnClick(){
    if (Build.VERSION.SDK_INT < 23) {
        phoneCall();
    }else {

        if (ActivityCompat.checkSelfPermission(mActivity,
                Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {

            phoneCall();
        }else {
            final String[] PERMISSIONS_STORAGE = {Manifest.permission.CALL_PHONE};
            //Asking request Permissions
            ActivityCompat.requestPermissions(mActivity, PERMISSIONS_STORAGE, 9);
        }
    }
}

@Override
public void onRequestPermissionsResult(int requestCode, String[] permissions, int[] grantResults) {
    boolean permissionGranted = false;
    switch(requestCode){
        case 9:
            permissionGranted = grantResults[0]== PackageManager.PERMISSION_GRANTED;
            break;
    }
    if(permissionGranted){
        phoneCall();
    }else {
        Toast.makeText(mActivity, "You don't assign permission.", Toast.LENGTH_SHORT).show();
    }
}

private void phoneCall(){
    if (ActivityCompat.checkSelfPermission(mActivity,
            Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
        Intent callIntent = new Intent(Intent.ACTION_CALL);
        callIntent.setData(Uri.parse("tel:12345678900"));
        mActivity.startActivity(callIntent);
    }else{
        Toast.makeText(mActivity, "You don't assign permission.", Toast.LENGTH_SHORT).show();
    }
}

Answer 14

对于来自拨号器的呼叫（无需许可）：

   fun callFromDailer(mContext: Context, number: String) {
        try {
            val callIntent = Intent(Intent.ACTION_DIAL)
            callIntent.data = Uri.parse("tel:$number")
            mContext.startActivity(callIntent)
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(mContext, "No SIM Found", Toast.LENGTH_LONG).show()
        }
    }

从应用程序直接调用（需要权限）：

  fun callDirect(mContext: Context, number: String) {
        try {
            val callIntent = Intent(Intent.ACTION_CALL)
            callIntent.data = Uri.parse("tel:$number")
            mContext.startActivity(callIntent)
        } catch (e: SecurityException) {
            Toast.makeText(mContext, "Need call permission", Toast.LENGTH_LONG).show()
        } catch (e: Exception) {
            e.printStackTrace()
            Toast.makeText(mContext, "No SIM Found", Toast.LENGTH_LONG).show()
        }
    }

允许：

<uses-permission android:name="android.permission.CALL_PHONE"></uses-permission>

Answer 15

为了使用意图进行呼叫活动，您应该请求适当的权限。

为此，您需要在AndroidManifest.xml文件中包含使用权限。

<uses-permission android:name="android.permission.CALL_PHONE" />

然后在您的活动中包含以下代码

if (ActivityCompat.checkSelfPermission(mActivity,
        Manifest.permission.CALL_PHONE) == PackageManager.PERMISSION_GRANTED) {
    //Creating intents for making a call
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:123456789"));
    mActivity.startActivity(callIntent);

}else{
    Toast.makeText(mActivity, "You don't assign permission.", Toast.LENGTH_SHORT).show();
}
