[英]Custom Progress Dialog hides the soft keyboard android
查詢描述:我正在使用透明主題的自定義進度對話框。 這很好用。 我面臨的問題是,當我的鍵盤打開並且我顯示自定義進度對話框時, 它強制關閉我的鍵盤。 但是,如果我使用默認的進度對話框,那么它工作正常。
:正如您所見,即使出現進度對話框后鍵盤仍然存在。 我想在自定義進度對話框中實現相同的功能。
:正如您所看到的,當對話框顯示時,鍵盤會消失。 每次用戶打開鍵盤時都會感到乏味。
這是我的代碼:
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中的對話框主題:
<style name="DialogTheme" parent="Theme.AppCompat.Light.Dialog">
<item name="colorAccent">@color/actionbar_gradient_endColor</item>
</style>
任何幫助將不勝感激。
<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,我想出了解決方案:
我看到Default Progress Dialog擴展了AlertDialog
。 但是,在我的代碼中,我正在擴展Dialog
類。
現在我正在擴展ProgressDialog
而不是Dialog
,這就像魅力一樣。
這是代碼:
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>
怎么打電話?:
ProgessDialog mProgressDialog = new MyCustomProgressDialog(this);
mProgressDialog.show(); //to show
mProgressDialog.dismiss(); //to dismiss
1.知道軟鍵盤是否顯示。
2.顯示或隱藏軟鍵盤
試試這個 。
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);
}
}
