Answer 1

有两种方法1）编程2）通过使用XML布局

1)=======> 

AlertDialog.Builder builder = new AlertDialog.Builder(this); 
builder.setView(layout); 
builder.setTitle("Title"); 
alertDialog = builder.create(); 
alertDialog.show(); 
alertDialog.getWindow().setLayout(600, 400); //Controlling width and height. 


         (or) 

alertDialog.show(); 
WindowManager.LayoutParams lp = new WindowManager.LayoutParams(); 

lp.copyFrom(alertDialog.getWindow().getAttributes()); 
lp.width = 150; 
lp.height = 500; 
lp.x=-170; 
lp.y=100; 
alertDialog.getWindow().setAttributes(lp); 

如果你想显示要显示的布局，如Alert dialog请参见this

2)========> 

choose.xml

<TextView 
    android:id="@+id/img" 
    android:layout_width="wrap_content" 
    android:text="@string/choose" 
    android:textSize="25dp" 
    android:textColor="#fff" 
    android:layout_height="50dp"/> 

<TableLayout android:id="@+id/table" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content" 
    android:background="#fff" 
    android:orientation="vertical"> 

    <TableRow 
     android:id="@+id/tr1" 
     android:orientation="horizontal" 
     android:layout_margin="10dp"> 
     <ImageView 
      android:contentDescription="@string/phone" 
      android:src="@drawable/phone" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"/> 
     <TextView 
      android:id="@+id/phnText" 
      android:layout_width="wrap_content" 
      android:text="@string/phone" 
      android:gravity="left|center_vertical" 
      android:layout_marginLeft="10dp" 
      android:textSize="25dp" 
      android:textColor="#000" 
      android:layout_height="50dp"/> 
    </TableRow> 
    <View 
      android:layout_width="fill_parent" 
      android:layout_height="1dip" 
      android:background="#FF000000" /> 

    <TableRow 
     android:id="@+id/tr2" 
     android:orientation="horizontal" 
     android:layout_margin="10dp"> 
     <ImageView 
      android:contentDescription="@string/sms" 
      android:src="@drawable/sms" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content"/> 
     <TextView 
      android:id="@+id/smsText" 
      android:layout_width="wrap_content" 
      android:text="@string/sms" 
      android:gravity="left|center_vertical" 
      android:layout_marginLeft="10dp" 
      android:textSize="25dp" 
      android:textColor="#000" 
      android:layout_height="50dp"/> 
    </TableRow> 

</TableLayout> 
</LinearLayout> 

显示这是弹出像下面

private void showPopUp() 
{ 
    final AlertDialog.Builder helpBuilder = new AlertDialog.Builder(this); 
    helpBuilder.setTitle(""); 

    LayoutInflater inflater = getLayoutInflater(); 
    final View checkboxLayout = inflater.inflate(R.layout.choose, null); 
    helpBuilder.setView(checkboxLayout); 

    final AlertDialog helpDialog = helpBuilder.create(); 
    helpDialog.show(); 

    TableRow tablerowPhone = (TableRow)checkboxLayout.findViewById(R.id.tr1); 
    TableRow tablerowSms = (TableRow)checkboxLayout.findViewById(R.id.tr2); 

    tablerowPhone.setOnClickListener(new OnClickListener() { 

     public void onClick(View v) { 

      helpDialog.dismiss(); 

      Uri callUri = Uri.parse("tel:" + listview_array[4]); 
      Intent intent = new Intent(Intent.ACTION_CALL, callUri); 
      startActivity(intent); 
     } 
    }); 

    tablerowSms.setOnClickListener(new OnClickListener() { 

     public void onClick(View v) { 

      helpDialog.dismiss(); 

      Uri smsUri = Uri.parse("sms:" + listview_array[4]); 
      Intent intent = new Intent(Intent.ACTION_VIEW, smsUri); 
      startActivity(intent); 
     } 
    }); 
} 

电话，你想要这个showPopUp()方法。这样就可以设置高度和宽度在XML文件中的布局

试试这个，这对我的作品，

AlertDialog.Builder builder = new AlertDialog.Builder(this); 
builder.setView(layout); 
builder.setTitle("Title"); 
alertDialog = builder.create(); 
alertDialog.getWindow().setLayout(600, 400); //Controlling width and height. 
alertDialog.show();
