Question

我在oncreate()方法中有搜索的edittext，但是每当我默认启动活动时，edittext都有RequestFocus()表示它会打开键盘启动活动。我想隐藏那个键盘。以下是我的代码：

public class TwoList extends AppCompatActivity {
    private final String TAG = this.getClass().getName();
    TextView tablenoset, orderidset;
    String OrderIdFromService, Kotidfromservice, item, str, wId, tid, tabletype, newmenuname, fromservertable, serverorderid, response, forcheck, newmenuoflist, uname, tabletid, converttostringtbid, comtid;
    int myvalue, convertedorderid, convertednewtid, convertedorderidforlist, quantityoflist, rateforlist, totalamountoflist, midforlist, tab_id;
    ListView leftList;
    String cntforb;
    ListView rightList;
    ArrayAdapter<String> adapter;

            inputMethodManager.hideSoftInputFromWindow(getCurrentFocus().getWindowToken(), 0);
        }
    }

Answer 1

你需要设置 manifeststs.xml中的android:windowSoftInputMode="stateHidden”

或尝试

android:windowSoftInputMode="adjustPan"

您还可以参考以下链接：

https://developer.android.com/training/keyboard-input/visibility.html#ShowOnStart

Answer 2

要隐藏键盘时使用此代码

View v = getCurrentFocus();
                if (v != null) {
                    InputMethodManager imm = (InputMethodManager)getSystemService(Context.INPUT_METHOD_SERVICE);
                    imm.hideSoftInputFromWindow(view.getWindowToken(), 0);
                }

Answer 3

在我的父版面上，添加

 android:focusable="true"
 android:focusableInTouchMode="true"

示例：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:focusable="true"
    android:focusableInTouchMode="true"
    android:orientation="vertical">

    <EditText
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:inputType="textEmailAddress"
        android:id="@+id/et1"/>

    <ListView
        android:layout_width="wrap_content"
        android:layout_height="match_parent">

    </ListView>

</LinearLayout>

Edittext无法在加载时隐藏键盘在android中
