几种方式设置全屏dialogfragment

在Android的全屏DialogFragment

安卓android
我试图展示一个几乎全屏，但我不能这样做。我显示的方式是直接从Android开发

FragmentManager f = ((Activity)getContext()).getFragmentManager();
FragmentTransaction ft = f.beginTransaction();
Fragment prev = f.findFragmentByTag("dialog");
if (prev != null) {
ft.remove(prev);
}
ft.addToBackStack(null);
// Create and show the dialog.
DialogFragment newFragment = new DetailsDialogFragment();
newFragment.show(ft, "dialog");

我知道天真地试图设置RelativeLayout在以FILL_PARENT和了minWidth和了minHeight。

<RelativeLayout
xmlns:android=" CodeGo.net
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="1000px"
android:minHeight="600px"
android:background="#ff0000">

我知道expect填补了广大的画面。但我似乎只在垂直方向，但只有调整到固定的宽度水平。我也试图设置窗口属性的代码，如下建议：但是这并没有帮助。我可能误解有关Android如何处理对话框，因为我是全新的吧。我怎么可以这样做？是否有任何其他方法来达到我的目标？ Android的设备：的EeePad 安卓3.0.1
更新：我现在设法得到它变成全屏幕，与在下面的代码

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

不幸的是，这是不是很想要我想要的。我肯定需要一个小的“填充”对话框周围，以显示背景。任何想法如何呢？

-------------------------------------------------------------------------------------------------------------------------
1. 请尝试切换到的LinearLayout，而不是相对。在测试时我是针对3.0的API。

public class FragmentDialog extends Activity {
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
Button button = (Button) findViewById(R.id.show);
button.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
showDialog();
}
});
}
@Override
public void onSaveInstanceState(Bundle outState) {
super.onSaveInstanceState(outState);
}
void showDialog() {
FragmentTransaction ft = getFragmentManager().beginTransaction();
DialogFragment newFragment = MyDialogFragment.newInstance();
newFragment.show(ft, "dialog");
}
public static class MyDialogFragment extends DialogFragment {
static MyDialogFragment newInstance() {
MyDialogFragment f = new MyDialogFragment();
return f;
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
View v = inflater.inflate(R.layout.fragment_dialog, container, false);
return v;
}
}

} 和布局：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
xmlns:android=" CodeGo.net
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:minWidth="1000dp"
android:minHeight="1000dp">
</LinearLayout>

的main.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android=" CodeGo.net
android:orientation="vertical"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#ffffff">
<Button android:id="@+id/show"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_weight="0"
android:text="show">
</Button>
</LinearLayout>

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme_Black_NoTitleBar_Fullscreen);
}

3. 尝试使用setStyle（）中的onCreate并重写onCreateDialog进行对话框没有标题

@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme);
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
Dialog dialog = super.onCreateDialog(savedInstanceState);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
return dialog;
}

或者只是覆盖的onCreate（）和同胞的setStyle代码。

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

4. 如果任何人在这个，我也有类似的经验，这一点，但事实证明，这个问题是我忘了从onCreateView（而不是返回默认super.onCreateView）返回视图。我只是回到了正确的views，并解决了这个问题。
5. 奇拉格Nagariya是正确的
CodeGo.net，除了'_Fullscreen“加法。它可以是无法从对话式派生的任何基本样式。 “android.R.style。也可以。
6. 确实是可以取决于如何布局定义。但为了保证在对话得到所需要的尺寸，最好的办法是，提供的LayoutParams示一次对话（而不是创建）。
在一个对话框被显示在OnStart方法，因此获得全宽为：

@Override public void onStart() {
super.onStart();
Dialog d = getDialog();
if (d!=null){
d.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
}
}

也提供一个或样式，就像一个NO_TITLE样式，最好的位置是在onCreate方法：

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

7. 问题全屏之前总是有一个填充，同时具有设置全屏。试试这个代码onActivityCreated（）方法：

public void onActivityCreated(Bundle savedInstanceState)
{
Window window = getDialog().getWindow();
LayoutParams attributes = window.getAttributes();
//must setBackgroundDrawable(TRANSPARENT) in onActivityCreated()
window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
if (needFullScreen)
{
window.setLayout(LayoutParams.MATCH_PARENT, LayoutParams.MATCH_PARENT);
}
}

其实Dialog, DialogFragment, Activity 能看到的界面,都是基于Window显示的;
也就是修改样式, 都是在修改window的样式;
所以,本质上方法都是一样的,唯一不同的就是获取window对象的方法不一样;Dialog 通过, getWindow() 获取;
Activity 也是通过, getWindow() 获取;
DialogFragment 则是getDialog().getWindow()获取;有了window对象, 就可以开始本文了:1:修改Dialog中window宽度和高度<code class="language-java hljs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">//public static final int FILL_PARENT = -1;
//public static final int MATCH_PARENT = -1;
//public static final int WRAP_CONTENT = -2;
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));//注意此处
dialog.setContentView(textView, new ViewGroup.LayoutParams(-2, -2));
dialog.getWindow().setLayout(-1, -2);//setLayout必须在 setContentView之后, 调用;并且 setBackgroundDrawable 必须设置
//这里的-1,-2可以设置为任意高度;</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li></ul>2:修改DialogFragment中window宽度和高度
在DialogFragment的onCreateView()方法中<code class="language-java hljs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">public View onCreateView(LayoutInflater inflater, @Nullable ViewGroup container, @Nullable Bundle savedInstanceState) {
final Window window = getDialog().getWindow();
View view = inflater.inflate(R.layout.dialog_fragment_layout, ((ViewGroup) window.findViewById(android.R.id.content)), false);//需要用android.R.id.content这个view
window.setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));//注意此处
window.setLayout(-1, -2);//这2行,和上面的一样,注意顺序就行;
return view;
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li></ul>3:附赠Activity中修改window的宽度和高度
在Activity的onAttachedToWindow方法中<code class="hljs java has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">@Override
public void onAttachedToWindow() {
Window window = getWindow();
WindowManager.LayoutParams attributes = getWindow().getAttributes();
attributes.width = 460;
attributes.height = 700;

getWindow().setAttributes(attributes);
super.onAttachedToWindow();
}</code><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li></ul><ul class="pre-numbering" style="box-sizing: border-box; position: absolute; width: 50px; top: 0px; left: 0px; margin: 0px; padding: 6px 0px 40px; border-right-width: 1px; border-right-style: solid; border-right-color: rgb(221, 221, 221); list-style: none; text-align: right; background-color: rgb(238, 238, 238);"><li style="box-sizing: border-box; padding: 0px 5px;">1</li><li style="box-sizing: border-box; padding: 0px 5px;">2</li><li style="box-sizing: border-box; padding: 0px 5px;">3</li><li style="box-sizing: border-box; padding: 0px 5px;">4</li><li style="box-sizing: border-box; padding: 0px 5px;">5</li><li style="box-sizing: border-box; padding: 0px 5px;">6</li><li style="box-sizing: border-box; padding: 0px 5px;">7</li><li style="box-sizing: border-box; padding: 0px 5px;">8</li><li style="box-sizing: border-box; padding: 0px 5px;">9</li><li style="box-sizing: border-box; padding: 0px 5px;">10</li></ul>Winodw的其实属性修改:<code class="language-java hljs has-numbering" style="display: block; padding: 0px; color: inherit; box-sizing: border-box; font-family: 'Source Code Pro', monospace;font-size:undefined; white-space: pre; border-radius: 0px; word-wrap: normal; background: transparent;">mWindow = getDialog().getWindow();
