Question

在Android 4.1中定位dialogfragment有问题，在其他版本的Android OS上一切正常，问题只出现在4.1中。所以我要做的是在屏幕底部定位片段，但在Android 4.1中它看起来像这样的空白： White space at bottom of the screen

我的代码：

public class ContactsDialog extends DialogFragment {

String contactNumber = null;
String skypeContact = null;
String userID = null;
int flatsCount = 0;

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {

    TextView contactTV, skypeTV;

    View layout = inflater.inflate(R.layout.contacts_dialog, container);

    contactTV = (TextView) layout.findViewById(R.id.contactNumber);
    skypeTV = (TextView) layout.findViewById(R.id.skypeName);
    RelativeLayout skypeContactsLayout = (RelativeLayout) layout.findViewById(R.id.skypeContactsLayout);
    RelativeLayout contactsLayout = (RelativeLayout) layout.findViewById(R.id.contactsLayout);
    RelativeLayout allUserFlats = (RelativeLayout) layout.findViewById(R.id.allUserFlats);

    contactNumber = getArguments().getString("contactNumber", null);
    skypeContact = getArguments().getString("skypeName", null);
    userID = getArguments().getString("userID", null);
    flatsCount = getArguments().getInt("flatsCount");

    if(TextUtils.isEmpty(skypeContact)) {
        skypeContactsLayout.setVisibility(View.GONE);
    }
    if (TextUtils.isEmpty(userID)) {
        allUserFlats.setVisibility(View.GONE);
    }
    if (flatsCount == 1) {
        allUserFlats.setVisibility(View.GONE);
    }

    String convertedNumber = convertNumber(contactNumber);

    contactTV.setText(convertedNumber);
    skypeTV.setText(skypeContact);

    WindowManager.LayoutParams params = getDialog().getWindow()
            .getAttributes();
    params.gravity = Gravity.BOTTOM | Gravity.CENTER;
    getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);
    getDialog().getWindow().setAttributes(params);

    contactsLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(Intent.ACTION_CALL);
            intent.setData(Uri.parse("tel:" + contactNumber));
            startActivity(intent);
        }
    });

    allUserFlats.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Intent intent = new Intent(getActivity(), MainActivity.class);
            intent.putExtra("userID", userID);
            getActivity().finish();
            startActivity(intent);
        }
    });
    skypeContactsLayout.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {

            if(isSkypeClientInstalled(getActivity())){
                Intent sky = new Intent("android.intent.action.VIEW");
                sky.setData(Uri.parse("skype:" + skypeContact));
                startActivity(sky);
            } else {
                Toast.makeText(getActivity(), "Skype не установлен", Toast.LENGTH_LONG).show();
            }


        }
    });

    return layout;
}

public boolean isSkypeClientInstalled(Context myContext) {
    PackageManager myPackageMgr = myContext.getPackageManager();
    try {
        myPackageMgr.getPackageInfo("com.skype.raider", PackageManager.GET_ACTIVITIES);
    }
    catch (PackageManager.NameNotFoundException e) {
        return (false);
    }
    return (true);
}

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setStyle(DialogFragment.STYLE_NO_FRAME, R.style.CustomDialog);
}

@Override
public void onStart() {
    super.onStart();
    getDialog().getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT, WindowManager.LayoutParams.WRAP_CONTENT);
    getDialog().setCanceledOnTouchOutside(true);

}

private String convertNumber(String number) {
    StringBuffer sb = new StringBuffer(number);
    sb.insert(2," (");
    sb.insert(7,") ");
    sb.insert(12,"-");
    sb.insert(15,"-");
    return String.valueOf(sb);
}
}

我还有下一个布局文件

android:layout_width="match_parent" android:layout_height="wrap_content">

</LinearLayout>

我的样式文件

<style name="CustomDialog" parent="@android:style/Theme.Holo.Light" >
    <item name="android:windowIsFloating">true</item>
</style>

Answer 1

首先尝试设置：

params.gravity = Gravity.BOTTOM | Gravity.CENTER_HORIZONTAL;

而不是

params.gravity = Gravity.BOTTOM | Gravity.CENTER;

另外，我认为这不是必要的：

getDialog().getWindow().requestFeature(Window.FEATURE_NO_TITLE);

因为您的样式DialogFragment.STYLE_NO_FRAME已禁用TITLE区域。

如果这没有帮助，请粘贴您的CustomDialog样式。

编辑：

尝试将您的风格改为：

<style name="CustomDialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowBackground">@android:color/white</item>
    <item name="android:background">@android:color/transparent</item>
</style>
