带输入框(EditText)的AlertDialog

一、Main Class：
public void search() {
   Builder dialog = new AlertDialog.Builder(this);
   LayoutInflater inflater = (LayoutInflater) this.getSystemService(Context.LAYOUT_INFLATER_SERVICE);
   LinearLayout layout = (LinearLayout)inflater.inflate(R.layout.dialogview, null);
   dialog.setView(layout);
   et_search = (EditText)layout.findViewById(R.id.searchC);
   dialog.setPositiveButton("查找", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
     String searchC = et_search.getText().toString();
     Intent intent = new Intent();
     Bundle bundle = new Bundle();
     bundle.putString("search", searchC);
     intent.putExtras(bundle);
     intent.setClass(ViewResultActivity.this, SearchResult.class);
     ViewResultActivity.this.startActivity(intent);
    }
   });
  
   dialog.setNegativeButton("取消", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
    
    }
   
   });
   dialog.show();
}

二、dialogview.xml
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:orientation="vertical"
android:layout_width = "fill_parent"
android:layout_height = "fill_parent"
>
<EditText
   android:id = "@+id/searchC"
   styles = "@style/edittext_style1"
   android:layout_width = "200px"
   android:layout_height = "wrap_content"
   android:gravity = "left"
   />

</LinearLayout>
