自定義對話框的寬度和高度

Question

我試圖做一個自定義對話框

LayoutInflater li = LayoutInflater.from(this); 
     View view = li.inflate(R.layout.rate_layout, null); 

     RelativeLayout rate = (RelativeLayout) view.findViewById(R.id.rateClick); 
     RelativeLayout close = (RelativeLayout) view.findViewById(R.id.closeBtn); 
     close.setClickable(true); 
     rate.setClickable(true);  

     final AlertDialog.Builder dd = new AlertDialog.Builder(this);   
     dd.setView(view); 
     dd.setCancelable(false); 

     final AlertDialog d = dd.create(); 
     d.show(); 

背景圖像有4種分辨率的，所以我只能做wrap content。

這裏是我的xml文件

<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     > 



    <RelativeLayout 
     android:id="@+id/rateClick" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerHorizontal="true" 
     android:background="@drawable/rate_now_button" /> 

    <RelativeLayout 
     android:id="@+id/imageView1" 
     android:layout_width="219dp" 
     android:layout_height="234dp" 
     android:layout_centerHorizontal="true" 
     android:layout_centerVertical="true" 
     android:background="@drawable/pop_up" > 

     <RelativeLayout 
      android:id="@+id/closeBtn" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:layout_alignParentRight="true" 
      android:layout_alignParentTop="true" 
      android:background="@drawable/close_button" > 
     </RelativeLayout> 

     <RelativeLayout 
     android:id="@+id/rateClick" 
     android:layout_width="wrap_content" 
     android:layout_height="wrap_content" 
     android:layout_centerHorizontal="true" 
     android:layout_alignParentBottom="true" 
     android:background="@drawable/rate_now_button" /> 

    </RelativeLayout> 

</RelativeLayout> 

這是我得到。我想如何刪除對話框佈局。白色的大邊框。

Answer 1

不要使用AlertDialog.Builder。試試這個。

Dialog d = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar); 

或

Dialog d = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen); 

你可以使用任何主題符合您的標準，或者創建自己的。請參閱this question和this other question的回答。另見available themes。

有關setContentView（），setCancelable（），show（）和其他您可能認爲有用的方法的文檔，請參閱Dialog。

Answer 2

嘗試這樣：

dialog_item = new Dialog(Pre_Venda_Digitacao_2.this); 
    dialog_item.setContentView(R.layout.layout_pre_venda_digitacao_add_produto); 
    Util.softKeyboard(dialog_item.getWindow(), false); 

    // Recuperar os componentes da janela e disponibilizar para as variáveis globais. 
    dialog_Item_getComponentes(); 

    /***********************OnShow do Dialog*****************************/ 
    dialog_item.setOnShowListener(new OnShowListener() { 
     @Override 
     public void onShow(DialogInterface dialog) { 
      //Recupera a menor fonte dentro do layout passado 
      float lower_font_size = AutoResizeTextView_Functions.Get_Lower_Font_Size(ll_add_produto, 1000); 

      //Seta menor fonte recuparada anteriormente para os textos do layout passado 
      AutoResizeTextView_Functions.Resize_Text(ll_add_produto, lower_font_size); 
     } 
    }); 

    dialog_item.setOnDismissListener(new OnDismissListener() { 

     @Override 
     public void onDismiss(DialogInterface dialog) { 
      dialog_item = null; 
      preVenda_Item = null; 
     } 
    }); 

    Display display = getWindowManager().getDefaultDisplay(); 
    int width  = display.getWidth(); 

    lp = new WindowManager.LayoutParams(); 
    lp.copyFrom(dialog_item.getWindow().getAttributes()); 
    lp.width = (int) (width - (width * 0.07)); //Tira 7% da largura total da tela para deixar um espaço na janela 
    lp.height = WindowManager.LayoutParams.WRAP_CONTENT; 

    dialog_item.getWindow().setAttributes(lp); 

    dialog_item.show(); 

Answer 3

你可以試試：

myDialog.show(); 
Window window = myDialog.getWindow(); 
window.setLayout(300, 300); 

Answer 4

爲此在您的rate_layout.xml：

<!-- begin snippet: js hide: false --> 
<?xml version="1.0" encoding="utf-8"?> 
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" 
    android:layout_width="wrap_content" 
    android:layout_height="wrap_content" 
    android:background="#0000" 
> 

您還需要創建和調用對話片段如果你沒有：

public class AddDialog extends DialogFragment 
{ 
    @Override 
    public Dialog onCreateDialog(Bundle savedInstanceState) 
    { 
     AlertDialog.Builder builder = new AlertDialog.Builder(getActivity()); 

     LayoutInflater inflater = getActivity().getLayoutInflater(); 

     builder.setView(inflater.inflate(R.layout.rate_layout, null)); 
     return builder.create(); 
    } 
} 

然後調用Dialog的功能：

public void SomeFunction() 
{ 
    DialogFragment d = new AddDialog(); 
    d.show(getSupportFragmentManager(), "some_dialog_refrence"); 
} 

Answer 5

WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE); 
Display display = wm.getDefaultDisplay(); 
DisplayMetrics metrics = new DisplayMetrics(); 
display.getMetrics(metrics); 
Double width = metrics.widthPixels*.7; 
Double height = metrics.heightPixels*.7; 
Window win = dialog.getWindow(); 
win.setLayout(width.intValue(), height.intValue()); 

Answer 6

我們可以設置寬度，這樣的自定義對話框的高度。

DisplayMetrics displayMetrics = new DisplayMetrics(); 
getWindowManager().getDefaultDisplay().getMetrics(displayMetrics); 
int screenHeight = displayMetrics.heightPixels; 
int screenWidth = displayMetrics.widthPixels; 

android.view.WindowManager.LayoutParams lp = new android.view.WindowManager.LayoutParams(); 
     lp.copyFrom(deleteDialog.getWindow().getAttributes()); 

// If we need to set background color of activity 
// We need to set this before calling show() method 
lp.dimAmount = 0.7f;  
deleteDialog.getWindow().setAttributes(lp); 
deleteDialog.show(); 

// we need to set width, height after calling show() method 
Window window = deleteDialog.getWindow(); 
window.setLayout(screenWidth - screenWidth/2), WindowManager.LayoutParams.WRAP_CONTENT);
