我在scrollView中有一个按钮。单击该按钮时,我需要一个PopupWindow,只要单击该按钮就会显示软键盘。这就是我的代码今天的样子:
final Button b = (Button) findViewById(R.id.button);
b.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
LayoutInflater layoutInflater = (LayoutInflater) getBaseContext().getSystemService(LAYOUT_INFLATER_SERVICE);
View popupView = layoutInflater.inflate(R.layout.popup, null);
final PopupWindow popupWindow = new PopupWindow(popupView,WindowManager.LayoutParams.MATCH_PARENT,WindowManager.LayoutParams.MATCH_PARENT,true);
popupWindow.showAtLocation(v.getRootView(), Gravity.FILL, 0, 0);
//Bring soft keyboard up : NOT WORKING
final InputMethodManager mInputMethodManager = (InputMethodManager) getBaseContext().getSystemService(Context.INPUT_METHOD_SERVICE);
EditText editText = (EditText) popupView.findViewById(R.id.editText);
mInputMethodManager.showSoftInput(editText, 0);
}
});
我的布局XML看起来像这样:
<?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" >
<EditText
android:id="@+id/yourViewsEditText"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:hint="Your Views"
>
</EditText>
</RelativeLayout>
当我尝试fill_parent而不是wrap_content时,它会通过填充整个屏幕开始。我正在努力实现这样的目标:

也许尝试使用以下xml布局:
<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:isScrollContainer="true" >
<EditText
android:id="@+id/yourViewsEditText"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:hint="Your Views" />
</RelativeLayout>
它应自动设置布局的高度,直到软键盘开始。

你可以像这样获得键盘的高度:
myLayout.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
@Override
public void onGlobalLayout() {
// TODO Auto-generated method stub
Rect r = new Rect();
parent.getWindowVisibleDisplayFrame(r);
int screenHeight = parent.getRootView().getHeight();
int heightDifference = screenHeight - (r.bottom - r.top);
loadDialog(heightDifference);
}
});
然后您可以使用键盘的高度和设备的宽度加载弹出窗口:
public void loadDialog(int height)
{
Display mDisplay = activity.getWindowManager().getDefaultDisplay();
int width = mDisplay.getWidth();
//load the popup window with the height and width...
}
