Question

我使用自定义对话框，但在移动设备和选项卡视图中使用，但是当我在选项卡上进行检查时，设计会更改

我要在所有设备上使用相同的对话框。

请参阅下面的代码。

private void startDialog() {

    final Dialog dialog = new Dialog(activity);
    int width = (int)(getResources().getDisplayMetrics().widthPixels*0.70);
    int height = (int)(getResources().getDisplayMetrics().heightPixels*0.65);
    dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));

    dialog.setContentView(R.layout.checkout_alert_dialog);
    dialog.show();
    dialog.getWindow().setLayout(width, height);


    btn_cancle = dialog.findViewById(R.id.btn_cancle);
    btn_cancle.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(activity, "Cancel coming soon", Toast.LENGTH_LONG).show();
            dialog.dismiss();
        }
    });

    btn_continue = dialog.findViewById(R.id.btn_continue);
    btn_continue.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            Toast.makeText(activity, " Ok coming soon", Toast.LENGTH_LONG).show();
            dialog.dismiss();
        }
    });
}

以下是 Dialog.xml

仅查看您的layout.xml布局height和width为match_parent即可创建一个空格。

只需用我的xml替换您的xml。

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="@dimen/_250sdp"
    android:layout_height="wrap_content"
    android:orientation="vertical"
    android:background="@color/white"
    >

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:orientation="vertical"
        >

        <LinearLayout
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

                android:layout_gravity="center_horizontal"
                android:layout_marginTop="@dimen/_30sdp"

             android:layout_height="@dimen/_1sdp"
             android:background="@color/view_color"

                android:gravity="center"
                android:layout_weight="1"
                />

             <View
                 android:layout_width="@dimen/_1sdp"
                 android:layout_height="@dimen/_45sdp"
                 android:background="@color/view_color"
                 />
            <Button
                android:id="@+id/btn_continue"
                android:layout_width="match_parent"
                android:layout_height="match_parent"

                android:background="@null"
                android:layout_weight="1"
                android:gravity="center"
                />
         </LinearLayout>
        </LinearLayout>
    </LinearLayout>
</LinearLayout>

并在java文件中删除以下三行无需在运行时更改height和width ：

int width = (int)(getResources().getDisplayMetrics().widthPixels*0.70);
 int height = (int)(getResources().getDisplayMetrics().heightPixels*0.65);
 dialog.getWindow().setLayout(width, height);

Answer 2

尝试自定义布局

custom.xml

public void playCycle(){
    int mCurrentPosition = mMediaPlayer.getCurrentPosition() / 1000;
    seek.setProgress(mCurrentPosition);
    if(music.isPlaying()){
        runnable= new Runnable() {
            @Override
            public void run() {
                playCycle();
            }
        };
        handler.postDelayed(runnable, 1000);
    }
}

在Java文件中

sudo /usr/bin/safaridriver --enable

使用打开对话框

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent" >
<ImageView
android:id="@+id/imageDialog"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
android:layout_marginRight="6dp" />
<TextView
android:id="@+id/textDialog"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:textColor="#FFF"
android:layout_toRightOf="@+id/imageDialog"/>
<Button
android:id="@+id/declineButton"
android:layout_width="100px"
android:layout_height="wrap_content"
android:text=" Submit "
android:layout_marginTop="5dp"
android:layout_marginRight="5dp"
android:layout_below="@+id/textDialog"
android:layout_toRightOf="@+id/imageDialog"
/>
</RelativeLayout>

关闭对话框使用

final Dialog dialog = new Dialog(context);
dialog.setContentView(R.layout.custom);
dialog.setTitle("Title");

Answer 3

替换

myAlertDialog.show();

作者

alertDialog.show();

然后

alertDialog.getWindow().setLayout(width,height);

它将完美运行

完整代码：

  private void startDialog() {
    AlertDialog.Builder myAlertDialog = new AlertDialog.Builder(this);
    myAlertDialog.setTitle("title");
    myAlertDialog.setMessage("use this");
    AlertDialog alertDialog = myAlertDialog.create();

    DisplayMetrics displaymetrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(displaymetrics);
    int width = (int) ((int)displaymetrics.widthPixels * 0.9);
    int height = (int) ((int)displaymetrics.heightPixels * 0.7);


    myAlertDialog.setPositiveButton("Gallery", new DialogInterface.OnClickListener() {
        public void onClick(DialogInterface arg0, int arg1) {
            Intent pictureActionIntent = null;

            pictureActionIntent = new Intent(Intent.ACTION_PICK,
                    android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
            startActivityForResult(pictureActionIntent, GALLERY_PICTURE);

        }
    });

    myAlertDialog.setNegativeButton("Camera", new DialogInterface.OnClickListener() {

        public void onClick(DialogInterface arg0, int arg1) {

            StrictMode.VmPolicy.Builder builder = new StrictMode.VmPolicy.Builder();
            StrictMode.setVmPolicy(builder.build());

            Intent intent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
            startActivityForResult(intent, 15);

        }
    });
    alertDialog.show();
    alertDialog.getWindow().setLayout(width,height);

}

如果仍然无法正常工作，则可以这样使用：

class DialogView extends DialogFragment {
    Context context;

    public static DialogView newInstance() {
        DialogView f = new DialogView();
        return f;
    }

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setStyle(DialogFragment.STYLE_NO_TITLE, android.R.style.Theme);
        context = this.getActivity();
    }

    @Override
    public Dialog onCreateDialog(Bundle savedInstanceState) {

        return new Dialog(getActivity(), getTheme()) {
            @Override
            public void onBackPressed() {
                //do your stuff

            }
        };
    }

    @Override
    public View onCreateView(LayoutInflater inflater, ViewGroup container,
                             Bundle savedInstanceState) {
        View view = inflater.inflate(R.layout.button_layout_view, container, false);
        setCancelable(false);
             //  RelativeLayout closeBtn = (RelativeLayout) view.findViewById(R.id.bottom_separator);  get button ids like this- gallery camera etc and you can use click listener on that

        DisplayMetrics metrics = context.getResources().getDisplayMetrics();
        int width = (int) (metrics.widthPixels * 0.90);
        int height = (int) (metrics.heightPixels * 0.95);
        this.getDialog().getWindow().setLayout(width, height);
        return view;
    }

    public static DisplayMetrics getDeviceMetrics(Context context) {
        DisplayMetrics metrics = new DisplayMetrics();
        WindowManager wm = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
        Display display = wm.getDefaultDisplay();
        display.getMetrics(metrics);
        return metrics;
    }

}

为此创建带有两个按钮和标题的xml

button_layout_view

然后像这样打电话：

 android.support.v4.app.FragmentTransaction ft = getSupportFragmentManager().beginTransaction();
        DialogFragment newFragment = DialogView.newInstance();
       newFragment.show(ft, "");

Answer 4

我个人更喜欢创建DialogFragment并设置宽度和高度，如下所示：

@Override
public void onResume() {
    super.onResume();
    Window window = getDialog().getWindow();
    int width = getArguments().getInt(BUNDLE_KEY_WIDTH);
    int height = getArguments().getInt(BUNDLE_KEY_HEIGHT);
    window.setLayout(width, height);
}

Answer 5

在两个设备中，对话框的宽度和高度都很好（您可以通过startDialog()方法进行设置）。如果您希望平板电脑设备中的ImageView较小，以便在移动设备和平板电脑中使用相同的比例，则应为它们使用不同的dimens文件：

首先，为图像定义尺寸：

内部dimens.xml

<dimen name="dialog_image_size">XXXdp</dimen>

然后，在10英寸平板电脑的 /res/values-sw720dp/dimens.xml 中和 /res/values-sw600dp/dimens.xml 中定义相同的尺寸>用于7英寸平板电脑，并为它们设置较小的dp。

现在，当您在平板电脑上时，将加载不同的尺寸，因此您可以使用较小的尺寸来保持与移动设备相同的比例。
