我试图实现dialogFragments。它们显示和解除罚款，但问题是对话框的宽度以及textviews。当我希望跨越多个时，文本视图将只在一行上。他们还实现滚动，所以我能看到所有内容的唯一方法就是用手指滚动。
这是XML
<TextView
android:id="@+id/website_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_alignParentTop="true"
android:layout_centerHorizontal="true"
android:layout_gravity="center_horizontal"
android:layout_margin="10dip"
android:text="@string/website_text"
android:textColor="@android:color/white" />
<TextView
android:id="@+id/email_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/website_text"
android:layout_centerHorizontal="true"
android:layout_gravity="center_horizontal"
android:layout_margin="10dip"
android:text="@string/email_text"
android:textColor="@android:color/white" />
<TextView
android:id="@+id/information_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/email_text"
android:layout_centerHorizontal="true"
android:layout_gravity="center_horizontal"
android:layout_margin="10dip"
android:text="@string/information_text"
android:textColor="@android:color/white" />
<TextView
android:id="@+id/copyright_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/information_text"
android:layout_centerHorizontal="true"
android:layout_gravity="center_horizontal"
android:layout_margin="10dip"
android:text="@string/copyright_text"
android:textColor="@android:color/white" />
<TextView
android:id="@+id/apparentmedia_text"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_below="@+id/copyright_text"
android:layout_centerHorizontal="true"
android:layout_gravity="center_horizontal"
android:layout_margin="10dip"
android:text="@string/apparentmedia_text"
android:textColor="@android:color/white" />
这是DialogFragment
公共类InformationDialog扩展了DialogFragment {
int mNum;
/**
* Create a new instance of MyDialogFragment, providing "num"
* as an argument.
*/
public static InformationDialog newInstance(int num) {
InformationDialog d = new InformationDialog();
// Supply num input as an argument.
Bundle args = new Bundle();
args.putInt("num", num);
d.setArguments(args);
return d;
}
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
mNum = getArguments().getInt("num");
// Pick a style based on the num.
int style = DialogFragment.STYLE_NORMAL, theme = 0;
switch ((mNum-1)%6) {
case 1: style = DialogFragment.STYLE_NO_TITLE; break;
case 2: style = DialogFragment.STYLE_NO_FRAME; break;
case 3: style = DialogFragment.STYLE_NO_INPUT; break;
case 4: style = DialogFragment.STYLE_NORMAL; break;
case 5: style = DialogFragment.STYLE_NO_TITLE; break;
case 6: style = DialogFragment.STYLE_NO_FRAME; break;
case 7: style = DialogFragment.STYLE_NORMAL; break;
}
switch ((mNum-1)%6) {
case 2: theme = android.R.style.Theme_Panel; break;
case 4: theme = android.R.style.Theme; break;
case 5: theme = android.R.style.Theme_Light; break;
case 6: theme = android.R.style.Theme_Light_Panel; break;
case 7: theme = android.R.style.Theme_Light; break;
}
setStyle(DialogFragment.STYLE_NORMAL, android.R.style.Theme_Light_Panel);
}
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container,
Bundle savedInstanceState) {
TextView websiteText, emailText;;
View v = inflater.inflate(R.layout.info, container, false);
v.setLayoutParams(new LinearLayout.LayoutParams(50, LayoutParams.WRAP_CONTENT, 1));
websiteText = (TextView) v.findViewById(R.id.website_text);
websiteText.setText(R.string.website_text);
websiteText.setWidth(300);
emailText =(TextView) v.findViewById(R.id.email_text);
emailText.setText(R.string.email_text);
Linkify.addLinks(emailText, Linkify.EMAIL_ADDRESSES);
Linkify.addLinks(websiteText, Linkify.WEB_URLS);
return v;
}
}
以及我如何称呼它
DialogFragment newFragment = MyDialog.newInstance();
newFragment.show(getFragmentManager(), "dialog");
