DialogFragment与ListView之间的额外空间 [英] DialogFragment with extra space below ListView
本文介绍了DialogFragment与ListView之间的额外空间的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
public class ChooseDialog extends DialogFragment implements
DialogInterface.OnClickListener {
String URLhome;
字符串标题;
字符串类型;
/ * public static ChooseDialog newInstance（）{
ChooseDialog dialog = new ChooseDialog（）;
Log.v（a，shit running）;
Bundle bundle = new Bundle（）;
dialog.setArguments（bundle）;
返回对话框;
} * /
public ChooseDialog（String type）{
this.type = type;
}
@Override
public void onCreate（Bundle bundle）{
super.onCreate（bundle）;
setCancelable（true）;
int style = DialogFragment.STYLE_NORMAL，theme = 0;
setStyle（style，theme）;
}
@Override
public Dialog onCreateDialog（Bundle savedInstanceState）{
AlertDialog.Builder builder = new AlertDialog.Builder（getActivity（））;
builder.setTitle（type）;
builder.setNegativeButton（取消，这个）;
LayoutInflater inflater =（LayoutInflater）getActivity（）。getSystemService（Context.LAYOUT_INFLATER_SERVICE）;
查看dialogLayout = inflater.inflate（R.layout.dialog，null）;
builder.setView（dialogLayout）;
final String [] items = {Red，Green，Blue};
builder.setAdapter（new ArrayAdapter< String>（getActivity（），android.R.layout.simple_list_item_1，items），
new DialogInterface.OnClickListener（）{
public void onClick（DialogInterface dialog，int which）{
Log.v（touc ...，items [which] .toString（））;
}}
）;
return builder.create（）;
}
@Override
public void onClick（DialogInterface dialog，int which）{
// TODO自动生成的方法存根
}
}
启动对话框的代码：
public OnClickListener listener = new OnClickListener（）{
public void onClick（View v）{
showNationalityDialog（）;
}
};
private void showNationalityDialog（）{
FragmentManager fm = getSupportFragmentManager（）;
ChooseDialog nationalityDialog = new ChooseDialog（国籍）;
nationalityDialog.show（fm，fragment_edit_name）;
}
解决方案
我知道这个问题从来没有很多关注，但我终于解决了这个问题。
通过使用我在XML中创建的列表视图，而不是设置构建器的适配器，我设法摆脱了所有的超量
新代码如下所示：
开关（editText.getId（））{
case（0）：
ListView list =（ListView）dialogLayout.findViewById（R.id.listView1）;
list.setAdapter（new ArrayAdapter< String>（activity，R.layout.dialoglist，
activity.getResources（）。getStringArray（R.array.ageArray）））;
list.setOnItemClickListener（new OnItemClickListener（）{
public void onItemClick（AdapterView<？> arg0，View arg1，int arg2，
long arg3）{
editText.setText activity.getResources（）。getStringArray（R.array.ageArray）[arg2]）;
dismiss（）;
}
}）;
builder =（Integer.parseInt（android.os.Build.VERSION.SDK）< 11）？ new AlertDialog.Builder（activity）：
new AlertDialog.Builder（activity，android.R.style.Theme_Translucent）;
builder.setNegativeButton（取消，这个）;
builder.setView（dialogLayout）;
return builder.create（）;
As you can see, below the bottom list element in my ListView, there is excess space I can't seem to be rid of. I've tried Relative and Linearlayout, both look like this. Here's the code:
public class ChooseDialog extends DialogFragment implements
DialogInterface.OnClickListener {
String URLhome;
String Title;
String type;
/* public static ChooseDialog newInstance() {
ChooseDialog dialog = new ChooseDialog();
Log.v("a", "shit runs");
Bundle bundle = new Bundle();
dialog.setArguments(bundle);
return dialog;
}*/
public ChooseDialog(String type) {
this.type = type;
}
@Override
public void onCreate(Bundle bundle) {
super.onCreate(bundle);
setCancelable(true);
int style = DialogFragment.STYLE_NORMAL, theme = 0;
setStyle(style, theme);
}
@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
AlertDialog.Builder builder = new AlertDialog.Builder(getActivity());
builder.setTitle(type);
builder.setNegativeButton("Cancel", this);
LayoutInflater inflater = (LayoutInflater) getActivity().getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View dialogLayout = inflater.inflate(R.layout.dialog, null);
builder.setView(dialogLayout);
final String[] items = {"Red", "Green", "Blue" };
builder.setAdapter(new ArrayAdapter<String>(getActivity(), android.R.layout.simple_list_item_1, items),
new DialogInterface.OnClickListener() {
public void onClick(DialogInterface dialog, int which) {
Log.v("touched: ", items[which].toString());
}}
);
return builder.create();
}
@Override
public void onClick(DialogInterface dialog, int which) {
// TODO Auto-generated method stub
}
}
And the code that launches the dialog:
public OnClickListener listener = new OnClickListener() {
public void onClick(View v) {
showNationalityDialog();
}
};
private void showNationalityDialog() {
FragmentManager fm = getSupportFragmentManager();
ChooseDialog nationalityDialog = new ChooseDialog("Nationality");
nationalityDialog.show(fm, "fragment_edit_name");
}
解决方案
I know this question never drew much attention, but I finally solved the problem.
By using the listview that I created in XML rather than setting the builder's adapter, I managed to get rid of all the excess space.
Here's what the new code looks like:
switch (editText.getId()) {
case (0) :
ListView list = (ListView) dialogLayout.findViewById(R.id.listView1);
list.setAdapter(new ArrayAdapter<String>(activity, R.layout.dialoglist,
activity.getResources().getStringArray(R.array.ageArray)));
list.setOnItemClickListener(new OnItemClickListener() {
public void onItemClick(AdapterView<?> arg0, View arg1, int arg2,
long arg3) {
editText.setText(activity.getResources().getStringArray(R.array.ageArray)[arg2]);
dismiss();
}
});
builder = (Integer.parseInt(android.os.Build.VERSION.SDK) < 11)? new AlertDialog.Builder(activity) :
new AlertDialog.Builder(activity, android.R.style.Theme_Translucent);
builder.setNegativeButton("Cancel", this);
builder.setView(dialogLayout);
return builder.create();
