[英]Custom dialog box width and height
我正在嘗試創建一個自定義對話框
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,所以我只能wrap content
。
這是我的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>
這就是我得到的。 我怎么想刪除對話框布局。 白色的大邊界。
不要使用AlertDialog.Builder。 試試這個。
Dialog d = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar);
要么
Dialog d = new Dialog(this, android.R.style.Theme_Translucent_NoTitleBar_Fullscreen);
您可以使用符合條件的任何主題,也可以創建自己的主題。 請參閱此問題的答案和其他問題 。 另請參閱可用主題 。
有關setContentView(),setCancelable(),show()以及您可能認為有用的其他方法的文檔,請參閱Dialog 。
你可以試試:
myDialog.show();
Window window = myDialog.getWindow();
window.setLayout(300, 300);
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());
嘗試這樣的事情:
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();
在rate_layout.xml
執行此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"
>
如果你沒有,你還需要創建並調用一個對話框Fragment:
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();
}
}
然后在函數中調用Dialog
:
public void SomeFunction()
{
DialogFragment d = new AddDialog();
d.show(getSupportFragmentManager(), "some_dialog_refrence");
}
我們可以像這樣設置自定義對話框的寬度,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);
