Question

这就是我现在正在做的事情。我收到以下错误

android.content.ActivityNotFoundException：找不到要处理的Activity 意图{act = android.intent.action.CALL dat = 16477210790}

 @Override
    public void onClick(View v) {
        Intent callIntent = new Intent(Intent.ACTION_CALL);
        callIntent.setData(Uri.parse(store_contact_no.getText().toString()));
        startActivity(callIntent);

    }

Answer 1

您不需要在清单中声明拨号意图过滤器，也不需要ACTION_DIAL的任何权限。寻找我的实现

private boolean isTelephonyEnabled(){
TelephonyManager tm = (TelephonyManager)getSystemService(TELEPHONY_SERVICE);
return tm != null && tm.getSimState()==TelephonyManager.SIM_STATE_READY;}

也很好检查设备上支持的电话

(defn-
  str<->int [str]
  (let [n (read-string str)]
    (if (integer? n) n)))

(with-open [file (reader "/path/to/foo.txt")]
    (try
      (doseq [v (clojure-csv.core/parse-csv file)]

        (clojure.java.jdbc/insert! db  :records 
                      nil
                      [(v 0) (v 1) (v 2) (str<->int (v 3))]))
      (println "Records inserted successfully")
      (Exception e
        (println (.getNextException e) e))))

使用此代码。这可能会对你有所帮助。

将此添加到您的清单

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

在“活动检查”权限中，

if (ContextCompat.checkSelfPermission(getApplicationContext(), Manifest.permission.CALL_PHONE) != PackageManager.PERMISSION_GRANTED) {
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
            requestPermissions(new String[]{Manifest.permission.CALL_PHONE}, 1);
        }
    } else {
        Call(sNumber);
    }

其中sNumber是您在字符串中的数字

然后覆盖onRequestPermissionsResult

    @RequiresApi(api = Build.VERSION_CODES.M)
@Override
public void onRequestPermissionsResult(int requestCode, String permissions[], int[] grantResults) {

    switch (requestCode) {
        case 100:
            if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {

                // permission was granted,
                Call(sNumber);

            } else {

                // permission denied, boo! Disable the
                // functionality that depends on this permission.

                if (ActivityCompat.shouldShowRequestPermissionRationale(this, Manifest.permission.CALL_PHONE)) {

                    requestPermissions(new String[]{Manifest.permission.CALL_PHONE}, 1);

                }
            }
            break;
    }
}

添加此方法，

 private void Call(String sNumber)
{
    Intent callIntent = new Intent(Intent.ACTION_CALL);
    callIntent.setData(Uri.parse("tel:" + sNumber));
    startActivity(callIntent);
}

如何在android中实现CALL intent？
