更改方向更改时自定义对话框的尺寸

问题描述：

如何在方向更改时更改android中的对话框的尺寸。在的onCreate更改方向更改时自定义对话框的尺寸

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))));

代码我想做同样的，当方向改变。请帮助

我建议你创建一个init方法，并把你想要在onCreate和方向变化期间发生的东西。

首先，你应该添加到您的活动XML

android:configChanges="keyboardHidden|orientation"

然后实现方法

@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)))); 
}

但你还是应该做的是对的onCreate了。

只是检查了这一点，它的自定义代码来设置对话框高度根据oriebtation：它通过实现这个我的对话成为灵活的工作对我来说...我M在平板电脑上使用这个..

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)); 
      }
