如何在对话框中设置边距

问题描述

我已经在我的Andorid应用程序中使用了对话框来展示广告。但是我必须显示这个对话框约50dp从buttom的顶部，所以我想我们应该设置对话框重力buttom并设置它的边框50dp.But我无法在对话框 .so请告诉我如何解决这个问题。

I have used Dialog for display ad in my Andorid app.But I have to display this Dialog about 50dp top from buttom so i think we should set Dialog Gravity buttom and set its buttom margine 50dp.But i'm unable to use margin in Dialog.so please can suggest me how to solve this.

XML：

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/popup_element"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:background="@drawable/dialogback"
    android:orientation="vertical" >

    <WebView
        android:id="@+id/webView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content" />

</LinearLayout>

Java：

final Dialog dialog = new Dialog(this);
dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
dialog.getWindow().setBackgroundDrawable(new ColorDrawable(0));
LayoutInflater inflator = (LayoutInflater) getApplicationContext()
        .getSystemService(Context.LAYOUT_INFLATER_SERVICE);
View view = inflator.inflate(R.layout.ad, null, false);
dialog.setContentView(view);
dialog.getWindow().setGravity(Gravity.BOTTOM);
dialog.setCancelable(true);
WebView webView = (WebView) dialog.findViewById(R.id.webView);
webView.loadUrl("");
webView.setWebViewClient(new MyWebViewClient());
webView.setOnClickListener(new OnClickListener() {

    @Override
    public void onClick(View v) {
        // TODO Auto-generated method stub
        dialog.dismiss();
    }
});
dialog.show();

推荐答案

我做了一个类似的笑脸对话框。我扩展对话框

I did a similar smiley dialog. I extend dialog

public class SmileCustomDialog extends Dialog {
Context mcontext;
GridView mGridview;

public GridView getGridview() {
    return mGridview;
}

public SmileCustomDialog(final Context context) {
    super(context, R.style.SlideFromBottomDialog);
    this.mcontext = context;
    LayoutInflater inflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
    View v = inflater.inflate(R.layout.emocategorydialog, null);
    mGridview = (GridView) v.findViewById(R.id.emogrid);
    mGridview.setSelector(new ColorDrawable(Color.TRANSPARENT));

    ImageAdapter mAdapter = new ImageAdapter(mcontext);
    mGridview.setAdapter(mAdapter);
    this.requestWindowFeature(Window.FEATURE_NO_TITLE);
    this.setContentView(v);

    WindowManager.LayoutParams params = this.getWindow().getAttributes();
    this.setCanceledOnTouchOutside(true);
    params.y = -100;
    this.getWindow().setAttributes(params);

}

}

但必不可少的是

WindowManager.LayoutParams params = yourDialog.getWindow().getAttributes(); // change this to your dialog.

params.y = -100; // Here is the param to set your dialog position. Same with params.x
        yourDialog.getWindow().setAttributes(params);

只需将其添加到您的对话框之前。

Just add this before your show your dialog.
