android自定义dialog弹出框、透明背景

Dialog是android开发过程中最常用到的组件之一，它包括以下几种类型：

警告对话框：Alertialog
进度对话框：ProgressDialog
日期选择对话框：DatePickerDialog
时间选择对话框：TimePickerDialog
自定义对话框：从Dialog继承

Dialog的创建方式有两种：

一是直接new一个Dialog对象，然后调用Dialog对象的show和dismiss方法来控制对话框的显示和隐藏。

二是在Activity的onCreateDialog(int id)方法中创建Dialog对象并返回，然后调用Activty的showDialog(int id)和dismissDialog(int id)来显示和隐藏对话框。

区别在于通过第二种方式创建的对话框会继承Activity的属性，比如获得Activity的menu事件等。

CondimentDialog.java

public class CondimentDialog extends Dialog{

private Context mContext;
private Button okButton;

public CondimentDialog(Context context, int theme) {
  super(context,theme);
  mContext = context;
  requestWindowFeature(Window.FEATURE_NO_TITLE);
  setContentView(R.layout.dialog);


  LayoutParams params = getWindow().getAttributes();
  params.height = LayoutParams.WRAP_CONTENT;
  params.width = LayoutParams.WRAP_CONTENT;
  getWindow().setAttributes((android.view.WindowManager.LayoutParams) params);

  okButton = (Button)findViewById(R.id.btnOK);
  okButton.setText("shuosdhsfsdfsdf");
  okButton.setOnClickListener(new Button.OnClickListener(){

   public void onClick(View v) {
   // TODO Auto-generated method stub
    Log.e("dialog dismiss","dismiss+++++++++++++++++++++++++++");
        dismiss();

   } }
  );

}

protected void onStop() {
  Log.e("dialog onStop","dialog onStop+++++++++++++++++++++++++++");
  }

}

TestAdroidtbActivity.java

public class TestAdroidtbActivity extends Activity {
/** Called when the activity is first created. */

private TextView textView;
private Button button_ok;
private Context mContext;

    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);


        textView = (TextView)this.findViewById(R.id.itemName);
        button_ok = (Button)this.findViewById(R.id.btnOK);

        button_ok.setOnClickListener(new OnClickListener() {

   @Override
   public void onClick(View v) {
    // TODO Auto-generated method stub
    Log.e("activity", "onclick....");
    CondimentDialog dialog = new CondimentDialog(TestAdroidtbActivity.this,R.style.dialog);
    dialog.setCanceledOnTouchOutside(false);
    dialog.show();
   }
  });
