fragment的显示隐藏
DialogFragment的显示和隐藏可以通过调用show()和dismiss()方法来实现。在DialogFragment的show()方法中,会创建并显示Dialog。而在dismiss()方法中,会隐藏并销毁Dialog。
对于软键盘的显示和隐藏,可以通过在DialogFragment中使用InputMethodManager来实现。可以在DialogFragment的onCreateView()方法中给EditText设置点击监听,在点击EditText时调用showInput()方法来显示软键盘。在showInput()方法中,获取InputMethodManager实例,然后调用showSoftInput()方法将软键盘显示出来。
这里提供一个示例代码:
private void showInput(View view) {
InputMethodManager imm = (InputMethodManager) getActivity().getSystemService(Context.INPUT_METHOD_SERVICE);
if (imm != null) {
view.requestFocus();
imm.showSoftInput(view, 0);
}
}
然后在DialogFragment的onCreateView()方法中给EditText设置点击监听,如下所示:
@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
View view = inflater.inflate(R.layout.dialog_fragment_layout, container, false);
EditText editText = view.findViewById(R.id.edit_text);
editText.setOnClickListener(new View.OnClickListener() {
@Override
public void onClick(View v) {
showInput(v);
}
});
return view;
}
这样,当EditText被点击时,就会调用showInput()方法显示软键盘。而在DialogFragment的dismiss()方法中,软键盘会自动隐藏掉。
