自定义进度对话框隐藏软键盘android

Question

查询说明：我正在使用带有透明主题的自定义进度对话框。这很好用。我面临的问题是，当我的键盘打开并且如果我显示自定义进度对话框然后它会强制关闭我的键盘。但是，如果我使用默认的进度对话框，那么它可以正常工作。

: 如您所见，即使出现进度对话框，键盘仍然存在。 我想在自定义进度对话框中实现相同的功能。

: 如您所见，当对话框显示时键盘会消失。感觉很乏味，每次用户都要打开键盘。

这是我的代码：

public class CustomProgressDialog extends Dialog {
private ImageView imageView;
private Context mContext;

public CustomProgressDialog(Context context) {
    super(context, R.style.DialogTheme);
    mContext = context;
    getWindow().setBackgroundDrawable(new ColorDrawable(android.graphics.Color.TRANSPARENT));
    WindowManager.LayoutParams wlmp = getWindow().getAttributes();
    wlmp.gravity = Gravity.CENTER_HORIZONTAL;
    getWindow().setAttributes(wlmp);
    setTitle(null);
    setCancelable(true);
    //setOnCancelListener(null);
    LinearLayout layout = new LinearLayout(context);
    layout.setOrientation(LinearLayout.VERTICAL);
    LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(200, 200);
    imageView = new ImageView(context);
    imageView.setBackgroundResource(R.drawable.custom_dialog);
    layout.addView(imageView, params);
    addContentView(layout, params);
}

@Override
public void show() {
    super.show();
    AnimationDrawable frameAnimation = (AnimationDrawable) imageView.getBackground();
    frameAnimation.start();
}

@Override
public void dismiss() {
    super.dismiss();
}
}

style.xml 中的对话框主题：

 <style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">
    <item name="colorAccent">@color/actionbar_gradient_endColor</item>
</style>

任何帮助将不胜感激。

<EditText android:id="@+id/et_search_category" 
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:layout_toLeftOf="@+id/imgClearSearch" 
    android:background="@drawable/rounded_rdt_txt" 
    android:hint="Search here..." 
    android:layout_centerVertical="true" 
    android:singleLine="true" />

最后，我想出了解决方案：

我看到默认进度对话框扩展了AlertDialog。但是，在我的代码中，我扩展了 Dialog 类。

现在我扩展 ProgressDialog 而不是 Dialog，这就像一个魅力。

代码如下：

public class MyCustomProgressDialog extends ProgressDialog {
private ImageView imageView;

public MyCustomProgressDialog(Context context) {
    super(context, R.style.TransparentProgressDialog);
    requestWindowFeature(Window.FEATURE_NO_TITLE);
    WindowManager.LayoutParams wlmp = getWindow().getAttributes();
    wlmp.gravity = Gravity.CENTER;
    getWindow().setAttributes(wlmp);
    setTitle(null);
    setCancelable(false);
    setOnCancelListener(null);

}

public MyCustomProgressDialog(Context context, int theme) {
    super(context, theme);
}

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.view_custom_progress_dialog);

    imageView = (ImageView) findViewById(R.id.centerImage);
    imageView.setBackgroundResource(R.drawable.custom_dialog);

}

@Override
public void show() {
    super.show();
    AnimationDrawable frameAnimation = (AnimationDrawable) imageView.getBackground();
    frameAnimation.start();
}

@Override
public void dismiss() {
    super.dismiss();
}
}

布局文件：

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent">

<ImageView
    android:id="@+id/centerImage"
    android:layout_width="80dp"
    android:layout_height="80dp"
    android:layout_centerInParent="true"
    android:visibility="visible" />
</RelativeLayout>

style.xml：

<style name="TransparentProgressDialog" parent="@android:style/Theme.Dialog">
    <item name="android:windowFrame">@null</item>
    <item name="android:windowBackground">@android:color/transparent</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowTitleStyle">@null</item>
    <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
    <item name="android:backgroundDimEnabled">true</item>
    <item name="android:background">@android:color/transparent</item>
</style>

怎么打电话？：

ProgessDialog mProgressDialog = new MyCustomProgressDialog(this);
mProgressDialog.show(); //to show
mProgressDialog.dismiss(); //to dismiss

1.知道软键盘是否显示。

2.显示或隐藏软键盘

试试这个。

private Context context;
private boolean isShow = false;

// soft keyboard is show or not
private boolean isSoftShowing() {
    // screen height
    int screenHeight = getWindow().getDecorView().getHeight();
    Rect rect = new Rect();
    getWindow().getDecorView().getWindowVisibleDisplayFrame(rect);

    return screenHeight - rect.bottom - getSoftButtonsBarHeight() != 0;
}

private int getSoftButtonsBarHeight() {
    DisplayMetrics metrics = new DisplayMetrics();
    // screen height ,not include navigation
    ((Activity) context).getWindowManager().getDefaultDisplay().getMetrics(metrics);
    int usableHeight = metrics.heightPixels;
    // real screen height
    ((Activity) context).getWindowManager().getDefaultDisplay().getRealMetrics(metrics);
    int realHeight = metrics.heightPixels;
    if (realHeight > usableHeight) {
        return realHeight - usableHeight;
    } else {
        return 0;
    }
}

@Override
public void show() {
    super.show();
    // hideSoftKeyboard
    if(isSoftShowing()){
        ((Activity)context).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_HIDDEN);
        isShow = true;
    }
    AnimationDrawable frameAnimation = (AnimationDrawable) imageView.getBackground();
    frameAnimation.start();
}

@Override
public void dismiss() {
    super.dismiss();
    if(isShow){
        ((Activity)context).getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_ALWAYS_VISIBLE);
    }
}
