Question

我想在用户完成EditText中的输入时点击API。我们怎么做？我只想要EditText。

Answer 1

首先添加这些属性以编辑文本

android:imeOptions="actionDone"
android:singleLine="true"

然后在编辑文本上使用此代码以查找用户何时按下

edittext.setOnKeyListener(new OnKeyListener() {
    public boolean onKey(View v, int keyCode, KeyEvent event) {
        // If the event is a key-down event on the "enter" button
        if ((event.getAction() == KeyEvent.ACTION_DOWN) &&
            (keyCode == KeyEvent.KEYCODE_ENTER)) {
          // Call API      
          return true;
        }
        return false;
    }
});

OR 像这样使用onEditorAction：

edittext.setImeOptions(EditorInfo.IME_ACTION_DONE);


etSearch.setOnEditorActionListener(new TextView.OnEditorActionListener()

                                           {
                                               @Override
                                               public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                                                   if (actionId == EditorInfo.IME_ACTION_DONE) {
                                                     //call api
                                                       return true;
                                                   }
                                                   return false;
                                               }
                                           }
        );

检查这是否对您有帮助：

edittext1.addTextChangedListener(new TextWatcher()
            {
                @Override public void beforeTextChanged(CharSequence s, int start, int count, int after)
                {

                }

                @Override public void onTextChanged(CharSequence s, int start, int before, int count)
                {
                    if(s.length()>0)
                    {

                    }

                }

                @Override public void afterTextChanged(Editable s)
                {
                  //Text change done
                }
            });

您需要将TextWatcher添加到Edittext

editText.addTextChangedListener(new TextWatcher() {  @Override
    public void  beforeTextChanged(CharSequence charSequence, int
        i,  int i1, int i2) {

    }

    @Override public void onTextChanged(CharSequence charSequence, int
    i, int i1, int i2) {

                if(charSequence.length()>2)
                {
                  //Write code for hitting API
                }    }

     @Override   public void afterTextChanged(Editable s) {

                                    } });

并且在onTextChanged（）方法中你可以编写你的逻辑来命中 API。我的意思是你可以修复一些字符长度，然后点击API;

 Thanks to all , i solve my problem this way 
edtTo.setOnEditorActionListener(new TextView.OnEditorActionListener() {
        @Override
        public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
            switch( actionId ) {
                case EditorInfo.IME_ACTION_DONE:
                    // clear editText focus and hide 
                    edtTo.clearFocus();

                    InputMethodManager imm = (InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(edtFrom.getWindowToken(), 0);


                    Log.e("Debug","Hit Api ");
                    break;
            }
            return true;
        }
    });
