如何在焦点更改时停止软键盘自动显示(OnStart 事

问题描述

我正在为使用 Android 2.2 的平板电脑进行开发.

I am developing for a tablet using Android 2.2.

我有一个用于新的可编辑实例的表单.当可编辑时，我想阻止用户编辑某些字段.我在我的 onStart-事件中管理它，设置 txt.setFocusableInTouchMode(false).这会强制将焦点移到我的表单中的下一个可聚焦的 EditText 上(这很棒)，但是在运行时，软键盘会自动出现在具有焦点的 EditText 上.有人知道如何阻止这种情况吗?

I have a form which I am using for new and editable instances. When editable, I want to stop the user from editing certain fields. I manage this in my onStart-event, setting the txt.setFocusableInTouchMode(false). This forces the focus to the next focusable EditText in my form (which is great), but when running, the soft keyboard automatically appears for the EditText with the focus. Anybody know how to stop this?

这是代码(在 onStart 事件中调用):

Here's the code (called in the onStart event):

private void PopulateFields(){
    TextView txtTitle = (TextView) this.findViewById(R.id.txtEquipmentEditTitle);
    AutoCompleteTextView txtMake = (AutoCompleteTextView) this.findViewById(R.id.autEquipmentEditMake);
    AutoCompleteTextView txtModel = (AutoCompleteTextView) this.findViewById(R.id.autEquipmentEditModel);
    EditText txtDesc = (EditText) this.findViewById(R.id.txtEquipmentEditDesc);
    TextView txtDeptKey = (TextView) this.findViewById(R.id.txtEquipmentEditDeptKey);
    EditText txtSerial = (EditText) this.findViewById(R.id.txtEquipmentEditSerialNo);
    EditText txtBarCode = (EditText) this.findViewById(R.id.txtEquipmentEditBarCode);

    txtTitle.setText("Edit Equipment");
    txtMake.setText(make);
    txtModel.setText(model);
    txtDesc.setText(desc);
    txtDeptKey.setText(Integer.toString(deptKey));
    txtSerial.setText(serial);
    txtBarCode.setText(barCode);
    txtMake.setEnabled(false);
    txtModel.setEnabled(false);
    txtDesc.setEnabled(false);
    txtMake.setClickable(false);
    txtMake.setFocusableInTouchMode(false);
    txtModel.setFocusableInTouchMode(false);
    txtDesc.setFocusableInTouchMode(false);
    txtMake.setFocusable(false);
    txtModel.setFocusable(false);
    txtDesc.setFocusable(false);
}

推荐答案

也许这会对你有所帮助:

Maybe this will help you:

getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_HIDDEN);

当第一次创建或调用活动时，将此方法放在你的activity的onCreate()方法中.

Put this method in the onCreate() method of your activity when the activity is first created or called.
