关于自定义dialog不能左右全屏的解决办法

<p>
先贴代码，马克留用，免得以后自己还要找....</p><p>
</p><p>dialog_xml:</p>

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

    <TextView
        android:id="@+id/tv_EditDialogTitle"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="15dip"
        android:gravity="center"
        android:paddingLeft="30dip"
        android:paddingRight="25dip"
        android:text="咨询"
        android:textColor="#1F1F1F"
        android:textSize="17sp" />

    <EditText
        android:id="@+id/et_EditDialogText"
        android:layout_width="match_parent"
        android:layout_height="100dip"
        android:layout_below="@id/tv_EditDialogTitle"
        android:layout_marginLeft="25dip"
        android:layout_marginRight="25dip"
        android:layout_marginTop="5dip"
        android:background="#EFE0B9"
        android:ellipsize="end"
        android:gravity="left"
        android:hint="请填写咨询内容"
        android:maxLines="4"
        android:padding="5dip"
        android:textColor="#AA9053"
        android:textColorHint="#AA9053" />

    <LinearLayout
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_below="@id/et_EditDialogText"
        android:layout_marginRight="25dip"
        android:layout_marginTop="5dip"
        android:gravity="right"
        android:orientation="horizontal">


        <TextView
            android:id="@+id/tv_SignUpDialogSubmitBt"
            android:layout_width="105dip"
            android:layout_height="35dip"
            android:background="@drawable/l_round_gray_bg"
            android:gravity="center"
            android:text="提交"
            android:textColor="#fff" />
    </LinearLayout>

</RelativeLayout>

java:

package com.example.yangletang.custom_commonent.others;

import android.app.Activity;
import android.app.AlertDialog;
import android.app.Dialog;
import android.content.Context;
import android.text.Editable;
import android.util.Log;
import android.view.Display;
import android.view.LayoutInflater;
import android.view.ViewGroup;
import android.view.Window;
import android.view.WindowManager;
import android.view.inputmethod.InputMethodManager;
import android.widget.EditText;
import android.widget.RelativeLayout;

import com.example.yangletang.R;

/**
 * 带有输入法的dialog
 *
 * @author LHT
 */
public class L_EditDialog extends Dialog {
    private Context context;
    private RelativeLayout layout;
    private Dialog dialog;
    private EditText et_EditDialogText;

    public L_EditDialog(Context context) {
        super(context);
        // TODO Auto-generated constructor stub
        this.context = context;
        InitView();
    }

    public L_EditDialog(Context context, boolean cancelable,
                        OnCancelListener cancelListener) {
        super(context, cancelable, cancelListener);
        // TODO Auto-generated constructor stub
    }

    public L_EditDialog(Context context, int theme) {
        super(context, theme);
        // TODO Auto-generated constructor stub
    }

    private void InitView() {
        LayoutInflater inflaterDl = LayoutInflater.from(context);
        layout = (RelativeLayout) inflaterDl.inflate(R.layout.l_editdialog,
                null);
        et_EditDialogText = (EditText) layout.findViewById(R.id.et_EditDialogText);
//        dialog = new AlertDialog.Builder(context).create();
        dialog = new Dialog(context);
        dialog.requestWindowFeature(Window.FEATURE_NO_TITLE);
        dialog.setContentView(layout);
    }

    public void showDialog() {
        dialog.show();
        dialog.getWindow().setContentView(layout);
        Window win = dialog.getWindow();
        win.getDecorView().setPadding(15, 0, 15, 0);
        WindowManager.LayoutParams lp = win.getAttributes();
        lp.width = WindowManager.LayoutParams.FILL_PARENT;
        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
        win.setAttributes(lp);
    }

    public void DissDialog() {
        dialog.dismiss();
    }
}

主要是：

  Window win = dialog.getWindow();
        win.getDecorView().setPadding(15, 0, 15, 0);
        WindowManager.LayoutParams lp = win.getAttributes();
        lp.width = WindowManager.LayoutParams.FILL_PARENT;
        lp.height = WindowManager.LayoutParams.WRAP_CONTENT;
        win.setAttributes(lp);

马克一个drawable，用于做圆角dialog:

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="rectangle">

    填充颜色
    <solid android:color="#fff"></solid>


    <!--<!– 线的宽度，颜色灰色 –>-->
    <!--<stroke-->
        <!--android:width="0.1dp"-->
        <!--android:color="#fff"></stroke>-->

    <!-- 矩形的圆角半径 -->
    <corners android:radius="3dp" />

</shape>

关于在

dialog = new AlertDialog.Builder(context).create();

不能自动弹出输入法的解决办法：

getWindow().setFlags(WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM,
         WindowManager.LayoutParams.FLAG_ALT_FOCUSABLE_IM);
