android - 即使在对话框窗口上使用 SOFT_INPUT_ADJUST_RESIZE，显示键盘时我的自定义 View DialogFragment 也不会调整大小

Question

我有以下自定义 View DialogFragment。

当我点击 EditText 时，会显示软键盘。目前，观察结果是

1. 对话框的位置有点“上推”。
2. 对话框未调整大小且对话框内容被阻止。

这是它的样子。

我不希望对话框内容被键盘覆盖。我已经根据https://stackoverflow.com/a/36295587/72437做了修改

getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

仍然，它根本没有帮助。

我也试过

dialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE | WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);

没有区别。 Dialog 未调整大小并且 Dialog 内容被阻止。除了在第一次时会立即显示软键盘，而不需要用户立即点击 EditText。

请问如何在显示软键盘时调整我的 Dialog 大小？

更新

我通过在 Activity 上应用相同的 XML 布局文件做了一个实验。 Activity 调整大小没有问题。

看起来 XML 布局文件本身没问题。

我使用的软输入方式是

<activity android:name="org.yccheok.jstock.gui.trading.sign_in.SignInFragmentActivity"
    android:screenOrientation="portrait"
    android:windowSoftInputMode="adjustResize|stateAlwaysVisible" />

这是完整的代码和布局文件。

Answer 1

经过调试，发现是

1. 不需要调用设置对话框高度的makeDialogShorter。
2. 不需要在 onGlobalLayout 期间调整软输入。

这是我的解决方案。我重构代码以使用 onCreateView 而不是 onCreateDialog，以使代码更短更简单。

package org.yccheok.jstock.gui.trading.sign_in;

import android.os.Bundle;
import android.support.v4.app.DialogFragment;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.view.WindowManager;
import android.widget.Button;

import org.yccheok.jstock.gui.R;

/**
 * Created by yccheok on 8/1/2018.
 */

public class SignInDialogFragment extends DialogFragment {

    public static SignInDialogFragment newInstance() {
        SignInDialogFragment signInDialogFragment = new SignInDialogFragment();
        return signInDialogFragment;
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
        final View view = inflater.inflate(R.layout.trading_sign_in_fragment, container);

        Button forgotPasswordButton = (Button)view.findViewById(R.id.forgot_password_button);
        Button signInButton = (Button)view.findViewById(R.id.sign_in_button);

        forgotPasswordButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
            }
        });

        signInButton.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View view) {
            }
        });

        signInButton.setEnabled(false);


        //set to adjust screen height automatically, when soft keyboard appears on screen
        getDialog().getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_ADJUST_RESIZE);

        return view;
    }
}

这是结果

我们现在有一个简短可爱的小对话:)
