如何使用對話框片段設置全屏對話框

Question

我正在使用對話框片段進行全屏對話框。我成功顯示對話框，但問題在於它的寬度和高度。它無法顯示全屏幕大小。我想設置寬度和高度，並像活動一樣累積全屏大小。請引導我如何設置對話框的寬度和高度以將其累積爲全屏尺寸。

CustomeDialogFramgnet：

public class CustomDialogFragment extends DialogFragment { 
    /** The system calls this to get the DialogFragment's layout, regardless 
    of whether it's being displayed as a dialog or an embedded fragment. */ 
    @Override 
    public View onCreateView(LayoutInflater inflater, ViewGroup container, 
          Bundle savedInstanceState) { 
     // Inflate the layout to use as dialog or embedded fragment 
     View rootView = inflater.inflate(R.layout.item_fragment, null, false); 

     Toolbar toolbar = (Toolbar) rootView.findViewById(R.id.toolbar); 
     toolbar.setTitle("Dialog title"); 

     ((AppCompatActivity) getActivity()).setSupportActionBar(toolbar); 

     ActionBar actionBar = ((AppCompatActivity) getActivity()).getSupportActionBar(); 
     if (actionBar != null) { 
      actionBar.setDisplayHomeAsUpEnabled(true); 
      actionBar.setHomeAsUpIndicator(android.R.drawable.ic_menu_close_clear_cancel); 
     } 

     return rootView; 
    } 

    /** The system calls this only when creating the layout in a dialog. */ 
    @Override 
    public Dialog onCreateDialog(Bundle savedInstanceState) { 
     // The only reason you might override this method when using onCreateView() is 
     // to modify any dialog characteristics. For example, the dialog includes a 
     // title by default, but your custom layout might not need it. So here you can 
     // remove the dialog title, but you must call the superclass to get the Dialog. 
     Dialog dialog = super.onCreateDialog(savedInstanceState); 
     dialog.requestWindowFeature(Window.FEATURE_NO_TITLE); 
     return dialog; 
    } 

    @Override 
    public void onCreateOptionsMenu(Menu menu, MenuInflater inflater) { 
     menu.clear(); 
     getActivity().getMenuInflater().inflate(R.menu.alert_dialog_input, menu); 
    } 

    @Override 
    public boolean onOptionsItemSelected(MenuItem item) { 
     int id = item.getItemId(); 

     if (id == R.id.action_save) { 
      // handle confirmation button click here 
      return true; 
     } else if (id == android.R.id.home) { 
      // handle close button click here 
      dismiss(); 
      return true; 
     } 

     return super.onOptionsItemSelected(item); 
    } 
}

Answer 1

創建您style.xml一個theme從Theme.AppCompat.Light.DarkActionBar延伸，類似如下：

<style name="DialogFragmentTheme" parent="Theme.AppCompat.Light.DarkActionBar"> 
    <item name="colorPrimary">@color/colorPrimary</item> 
    <item name="colorPrimaryDark">@color/colorPrimaryDark</item> 
    <item name="colorAccent">@color/colorAccent</item> 

    <item name="android:paddingRight">0dp</item> 
    <item name="android:paddingLeft">0dp</item> 
    <item name="android:layout_width">match_parent</item> 
    <item name="android:windowNoTitle">true</item> 
</style> 

，並設置style創建同時打開dialog，類似下面：

CustomDialogFragment mDialog = new CustomDialogFragment(); 
... 
mDialog.setStyle(DialogFragment.STYLE_NORMAL, R.style.DialogFragmentTheme); 
mDialog.show(getSupportFragmentManager(), "DialogFragment"); 

Answer 2

組此行創建對話框後。

dialog.getWindow().setLayout(LinearLayout.LayoutParams.MATCH_PARENT, LinearLayout.LayoutParams.MATCH_PARENT); 

如果要創建自定義DialogFragment在DialogFragment的onCreate這樣寫：

setStyle(DialogFragment.STYLE_NORMAL,android.R.style.Theme_Black_NoTitleBar_Fullscreen); 

reference

Answer 3

這樣創建主題和創建對話框

後添加到您的對話框

<style name="ThemeDialog" parent="android:Theme.Holo.Dialog"> 
    <item name="android:windowMinWidthMajor">100%</item> 
    <item name="android:windowMinWidthMinor">100%</item> 
</style> 

組此行

getDialog().getWindow() 
      .getAttributes().windowAnimations = R.style.ThemeDialog; 
    WindowManager.LayoutParams wmlp = getDialog().getWindow().getAttributes(); 
    wmlp.gravity = Gravity.FILL_HORIZONTAL; 
    getDialog().getWindow().setBackgroundDrawable(new ColorDrawable(0)); 
    getDialog().requestWindowFeature(Window.FEATURE_NO_TITLE); 

Answer 4

添加此行在onCreate你膨脹你的佈局。

getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT); 

Answer 5

在style.xml創建如下主題：

<style name="DialogTheme" parent="Theme.AppCompat.Light.DarkActionBar"> 
    <item name="android:paddingRight">0dp</item> 
    <item name="android:paddingLeft">0dp</item> 
    <item name="android:layout_width">match_parent</item> 
    <item name="android:windowNoTitle">true</item> 
</style> 

然後設置樣式DialogFragment

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