Java 动画编辑后，文本将被聚焦以进行键入

我正在尝试在动画发生后将我的EditText聚焦以展开它。我尝试通过编程设置焦点，在Xml中也尝试过。我已经没有办法解决这个问题了，但必须有人知道

主要活动

public void onSearchExpand(View view){
    w_SearchBarFullScreen.setVisibility(View.VISIBLE);
    SearchBarExpand = AnimationUtils.loadAnimation(MainActivity.this,R.anim.web_search_expand);
    w_SearchBarFullScreen.startAnimation(SearchBarExpand);
    w_Toolbar.startAnimation(FadeOut);
    w_SearchBarFullScreen.setFocusable(true);
}

XMl

但现在的问题是让键盘显示出焦点，有什么建议吗

由于使用了动画侦听器，我留下了这个错误

您需要一个监听器，它将在动画完成时触发，所以请执行此操作

FadeOut.setAnimationListener(new AnimationListener() {
    public void onAnimationStart(Animation anim){};
    public void onAnimationRepeat(Animation anim){};
    public void onAnimationEnd(Animation anim)
    {
        // as mentioned by lib4
        w_SearchBarFullScreen.requestFocus();
    };
}); 

因为，当前您在动画完成之前请求聚焦

或者您可以尝试通过xml将其添加为

<EditText  ...>
    <requestFocus/>
</EditText>

---

您可能可以试试这个，一个重要的想法是您可以使用requestFocus（）来获得焦点

SearchBarExpand.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {

            }

            @Override
            public void onAnimationEnd(Animation animation) {
               w_SearchBarFullScreen.requestFocus();
            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });

SearchBarExpand.start();

如果EditText获得焦点但键盘未显示，则应在onAnimationEnd（）中尝试以下操作：-

使用这个对我来说很有用

 public void onSearchExpand(View view){
    w_SearchBarFullScreen.setVisibility(View.VISIBLE);

   w_SearchBarFullScreen.startAnimation(SearchBarExpand);
   w_Toolbar.startAnimation(FadeOut);

   if(w_SearchBarFullScreen.getVisibility() == View.VISIBLE){
       w_SearchBarFullScreen.requestFocus();
       w_SearchBarFullScreen.setText("   ");
       InputMethodManager imm = (InputMethodManager)   getSystemService(Context.INPUT_METHOD_SERVICE);
       assert imm != null;
       imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
   }

为什么不将w_searchbar全屏显示。setFocusable（false）@EquiWare查看我的答案，如何在其中显示软键盖..查看新编辑了解为什么Logcat与AnimationListener错误与Animation Listener一起出现，我在想我是如何将其放入动画中的？您是否调用了SearchBarExpand.start（）；？很抱歉，我最终找到了答案，检查UpdateGetWidow（）.setSoftInputMode（WindowManager.LayoutParams.SOFT\u INPUT\u STATE\u ALWAYS\u VISIBLE）；用这个来显示键盘让我们看看。

SearchBarExpand.setAnimationListener(new Animation.AnimationListener() {
            @Override
            public void onAnimationStart(Animation animation) {

            }

            @Override
            public void onAnimationEnd(Animation animation) {
               w_SearchBarFullScreen.requestFocus();
            }

            @Override
            public void onAnimationRepeat(Animation animation) {

            }
        });

SearchBarExpand.start();

@Override
public void onAnimationEnd(Animation animation) {

    if(w_SearchBarFullScreen.requestFocus()) {
        getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
    }
}

 public void onSearchExpand(View view){
    w_SearchBarFullScreen.setVisibility(View.VISIBLE);

   w_SearchBarFullScreen.startAnimation(SearchBarExpand);
   w_Toolbar.startAnimation(FadeOut);

   if(w_SearchBarFullScreen.getVisibility() == View.VISIBLE){
       w_SearchBarFullScreen.requestFocus();
       w_SearchBarFullScreen.setText("   ");
       InputMethodManager imm = (InputMethodManager)   getSystemService(Context.INPUT_METHOD_SERVICE);
       assert imm != null;
       imm.toggleSoftInput(InputMethodManager.SHOW_FORCED, 0);
   }
