Android完成按钮操作onclick

Question

我正在开发android。在我的登录页面中，我有一个提交按钮，它工作正常。现在我需要让Android键盘“完成”按钮操作具有相同的提交按钮功能。我怎样才能做到这一点？任何帮助都会提前感谢。

Answer 1

您需要为Edittext实施OnEditorActionListener。喜欢

editText.setOnEditorActionListener(new OnEditorActionListener() {        
    @Override
    public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
        if(actionId==EditorInfo.IME_ACTION_DONE){
            //TODO: do something
        }
    return false;
    }
});

Answer 2

这是我发现的

class DoneOnEditorActionListener implements OnEditorActionListener {
@Override
public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
    if (actionId == EditorInfo.IME_ACTION_DONE) {
        InputMethodManager imm = (InputMethodManager)v.getContext().getSystemService(Context.INPUT_METHOD_SERVICE);
        imm.hideSoftInputFromWindow(v.getWindowToken(), 0);
        return true;    
    }
    return false;
}

}

使用OnEditorActionListener

尝试此操作

EditText edit = (EditText)findViewById(R.id.edit);

        edit.setOnEditorActionListener(new OnEditorActionListener() {
            public boolean onEditorAction(TextView v, int actionId, KeyEvent event) {
                if ((event != null && (event.getKeyCode() == KeyEvent.KEYCODE_ENTER)) || (actionId == EditorInfo.IME_ACTION_DONE)) {
                    Log.i("check","Enter pressed");
                }    
                return false;
            }
        });
