1)当我的应用程序启动时,它显示带有呼叫按钮的警报对话框。如果它是手机而不是我必须允许用户呼叫。如果它是平板电脑而不是点击按钮skype应该打开并且如果没有安装skype Play商店中。
public class MainActivity extends Activity {
private Button call_btn, cancle_btn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
call_btn = (Button) findViewById(R.id.call_button);
cancle_btn = (Button) findViewById(R.id.cancel_button);
call_btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:123456789"));
startActivity(callIntent);
}
});
}
}

使用此方法,您实际上可以确定它是平板电脑还是手机:
public static boolean isTablet(Context context) {
return (context.getResources().getConfiguration().screenLayout
& Configuration.SCREENLAYOUT_SIZE_MASK)
>= Configuration.SCREENLAYOUT_SIZE_LARGE;
}
因此,您已经编写的代码应该可以正常使用手机来拨打电话。对于平板电脑,您可以使用此方法进行Skype调用:
public static void skype(String number, Context ctx) {
try {
Intent sky = new Intent("android.intent.action.VIEW");
sky.setData(Uri.parse("skype:" + number));
ctx.startActivity(sky);
} catch (ActivityNotFoundException e) {
//Skype not installed
}
}
ActivityNotFoundException
可以被捕获,这意味着Skype尚未安装。
因此,您可以使用此代码将用户带到Playstore:
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("http://play.google.com/store/apps/details?id=com.skype.raider" )));
P.S :如果您的唯一要求是查找是平板电脑还是手机,则上述方法有效。如果您想查找Sim是否存在或任何此类内容,您可以使用其他答案中的代码。
答案 1 :(得分:1)
以下是检查设备是手机还是平板电脑的快速示例
TelephonyManager manager =
(TelephonyManager) getSystemService(Context.TELEPHONY_SERVICE);
if (manager.PhoneType == PhoneType.None) {
// Not a phone, open Skype
}
else {
// It is a phone, show dial
}
您可以通过确保 SIM 卡可用来进一步了解
if (manager.getSimState() != TelephonyManager.SIM_STATE_ABSENT){
// Open skype
} else {
// Can dial
}
将此答案与显示如何启动Skype的其他答案相结合,您应该有一个可行的解决方案!
答案 2 :(得分:1)
您可以按照步骤来达到要求。
第1步:您可以将此代码保留在按钮单击或onCreate下。
if(isTelePhonyAvailable()){
//Do Telephony calling stuff
} else if(isSkypeInstalled()){
//Do Skype calling stuff
} else {
//Open google play to download the skype application
openGooglePlayToDownloadSkype();
}
第2步:只需将这些方法复制粘贴到您的活动文件中即可。方法名称将清楚地表明他们正在做什么。
private boolean isTelePhonyAvailable(){
TelephonyManager tm= (TelephonyManager)getSystemService(Context.TELEPHONY_SERVICE);
if(tm.getPhoneType()==TelephonyManager.PHONE_TYPE_NONE){
return false;
}
return true;
}
private boolean isSkypeInstalled(){
boolean isInstalled = false;
String appPackageName = "com.skype.raider";
PackageManager pm = getPackageManager();
try {
pm.getPackageInfo(appPackageName, PackageManager.GET_ACTIVITIES);
isInstalled = true;
} catch (PackageManager.NameNotFoundException e) {
isInstalled = false;
}
return isInstalled;
}
private void openGooglePlayToDownloadSkype(){
String appPackageName = "com.skype.raider";
startActivity(new Intent(Intent.ACTION_VIEW, Uri.parse("market://details?id=" + appPackageName)));
}
第3步:最后您需要一些权限。
<uses-permission android:name="android.permission.READ_PHONE_STATE" />
希望它会对你有所帮助.. :)

试试这种方式
Intent intent = new Intent(Intent.ACTION_CALL);
PackageManager manager = mContext.getPackageManager();
List<ResolveInfo> list = manager.queryIntentActivities(intent, 0);
if (list != null && list.size() > 0) {
//At least one activity available to make calls
} else {
//No activity to handle calls.//start skype call
}

尝试一下:
public class MainActivity extends Activity{
public Button call_btn, cancel_btn;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
call_btn = (Button) findViewById(R.id.call_button);
cancle_btn = (Button) findViewById(R.id.cancel_button);
call_btn.setOnClickListener(new OnClickListener() {
@Override
public void onClick(View v) {
if(deviceIsTablet){
if(isAppInstalled("com.skype.android")){
}else{
}
}else{
Intent callIntent = new Intent(Intent.ACTION_CALL);
callIntent.setData(Uri.parse("tel:123456789"));
startActivity(callIntent);
}
}
});
}
// determine whether or no the android device is a tablet or not
public static boolean deviceIsTablet(Context c) {
return (c.getResources().getConfiguration().screenLayout
& Configuration.SCREENLAYOUT_SIZE_MASK)
>= Configuration.SCREENLAYOUT_SIZE_LARGE;
}
private boolean isAppInstalled(String app) {
PackageManager packagemanager = getPackageManager();
boolean isOnDevice = false;
try {
packagemanager.getPackageInfo(app, PackageManager.GET_ACTIVITIES);
isOnDevice = true;
} catch (PackageManager.NameNotFoundException exception) {
isOnDevice = false;
}
return isOnDevice;
}
}
