我试图在使用 NumberPicker 输入数值时关闭软键盘(出于美学原因)。这是我的布局 xml 代码:
<?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:orientation="vertical" >
<LinearLayout
android:id="@+id/linearLayout2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:layout_marginBottom="30dp"
android:layout_marginTop="30dp" >
<NumberPicker
android:id="@+id/repetitionPicker"
android:layout_width="40dp"
android:layout_height="wrap_content" />
<TextView
android:id="@+id/textView1"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="@string/repetitions_short_divider"
android:textAppearance="?android:attr/textAppearanceMedium" />
<NumberPicker
android:id="@+id/weightPicker"
android:layout_width="40dp"
android:layout_height="wrap_content"
android:layout_marginLeft="40dp" />
<TextView
android:id="@+id/textView2"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_vertical"
android:text="@string/pounds"
android:textAppearance="?android:attr/textAppearanceMedium" />
</LinearLayout>
<Button
android:id="@+id/saveButton"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_gravity="center_horizontal"
android:text="@string/save" />
</LinearLayout>
最后,这是我尝试在 onCreate ()-方法中阻塞键盘的代码:
// hide keyboard
View.OnClickListener disableKeyBoardListener = new View.OnClickListener() {
public void onClick(View v) {
((InputMethodManager) getSystemService(Context.INPUT_METHOD_SERVICE))
.hideSoftInputFromWindow(v.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
}
};
((EditText) weightPicker.getChildAt(1)).setInputType(InputType.TYPE_NULL);
((EditText) repetitionPicker.getChildAt(1)).setInputType(InputType.TYPE_NULL);
((EditText) weightPicker.getChildAt(1)).setOnClickListener(disableKeyBoardListener);
//((EditText) repetitionPicker.getChildAt(1)).setOnClickListener(disableKeyBoardListener);
//weightPicker.setOnClickListener(disableKeyBoardListener);
//repetitionPicker.setOnClickListener(disableKeyBoardListener);
getWindow().setSoftInputMode(
WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
遗憾的是,当点击数字选择器时,软键盘仍然会出现。有什么主意吗?
