方向更改時更改自定義對話框的尺寸

Question

方向更改時如何在android中更改Dialog的尺寸。

onCreate中的代碼

static final float[] DIMENSIONS_DIFF_LANDSCAPE = {20, 60};
static final float[] DIMENSIONS_DIFF_PORTRAIT = {40, 60};

final float scale = getContext().getResources().getDisplayMetrics().density;
int orientation = getContext().getResources().getConfiguration().orientation;

float[] dimensions =
                (orientation == Configuration.ORIENTATION_LANDSCAPE)
                        ? DIMENSIONS_DIFF_LANDSCAPE : DIMENSIONS_DIFF_PORTRAIT;
                 addContentView(mContent, new LinearLayout.LayoutParams(
                    display.getWidth() - ((int) (dimensions[0] * scale + 0.5f)),
                    display.getHeight() - ((int) (dimensions[1] * scale + 0.5f))));

當方向改變時，我想做同樣的事情。 請幫忙

只需檢查一下它是一個自定義代碼即可根據Oretbtation設置對話框高度：它通過實現此功能對我有用，使對話框變得靈活...在平板電腦中使用此功能即可。

WindowManager winMan = (WindowManager) context.getSystemService(Context.WINDOW_SERVICE);
            int height = winMan.getDefaultDisplay().getHeight();
            int width=winMan.getDefaultDisplay().getWidth();
            if(height>width){

                if(DeviceType.getDeviceType(context)==Device.NEXUS7){
                dialoglayout.setLayoutParams(new FrameLayout.LayoutParams(700,1100));
                }else if (DeviceType.getDeviceType(context)==Device.GALAXYTAB2){
                    dialoglayout.setLayoutParams(new FrameLayout.LayoutParams(580,900));
                }else if(DeviceType.getDeviceType(context)==Device.GALAXY10){
                    dialoglayout.setLayoutParams(new FrameLayout.LayoutParams(700,1100));
                }


            else{
                if(DeviceType.getDeviceType(context)==Device.NEXUS7){
                    dialoglayout.setLayoutParams(new FrameLayout.LayoutParams(700,700));
                }else if (DeviceType.getDeviceType(context)==Device.GALAXYTAB2){
                    dialoglayout.setLayoutParams(new FrameLayout.LayoutParams(700,500));
                    System.out.println("galaxy tab 2 landescape");
                }else if(DeviceType.getDeviceType(context)==Device.GALAXY10){
                dialoglayout.setLayoutParams(new FrameLayout.LayoutParams(700,700));
            }

我建議您創建一個方法init，然后將要發生的事情放在onCreate和方向更改中。

首先，您應該將此添加到您的活動xml中

android:configChanges="keyboardHidden|orientation"

然后實施方法

@Override
public void onConfigurationChanged(Configuration newConfig) {
    super.onConfigurationChanged(newConfig);

    static final float[] DIMENSIONS_DIFF_LANDSCAPE = {20, 60};
    static final float[] DIMENSIONS_DIFF_PORTRAIT = {40, 60};

    final float scale = getContext().getResources().getDisplayMetrics().density;

    float[] dimensions =
                (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE)
                        ? DIMENSIONS_DIFF_LANDSCAPE : DIMENSIONS_DIFF_PORTRAIT;
                 addContentView(mContent, new LinearLayout.LayoutParams(
                    display.getWidth() - ((int) (dimensions[0] * scale + 0.5f)),
                    display.getHeight() - ((int) (dimensions[1] * scale + 0.5f))));
}

但是您仍然應該在onCreate上執行此操作。
