android中拨打电话

一、在manifest中注册权限

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

二、6.0以上要动态申请权限

if (Build.VERSION.SDK_INT >= 23) {
    int REQUEST_CODE_CONTACT = 101;
    String[] permissions = {Manifest.permission.CALL_PHONE};
    //验证是否许可权限
    for (String str : permissions) {
        if (this.checkSelfPermission(str) != PackageManager.PERMISSION_GRANTED) {
            //申请权限
            this.requestPermissions(permissions, REQUEST_CODE_CONTACT);
            return;
        }
    }
}

三、点击某个控件 触发拨打电话

Intent intent = new Intent(Intent.ACTION_CALL);
Uri data = Uri.parse("tel:"+phoneNumber);
intent.setData(data);
startActivity(intent);
