自定義Dialog

如圖是效果圖，第一個按鈕當按下時彈出一個自定義的Dialog，第二個和第三個分別是ProgressBar，只是簡單的改變了樣式

第1個ProgressBar是逆時針方向，第2 個時順時針方向

如下是主代碼

package com.demo.sb.main;

import com.demo.suibian.R;
import android.app.Activity;
import android.app.AlertDialog;
import android.os.Bundle;
import android.view.Display;

import android.view.View.OnClickListener;
import android.view.WindowManager;
import android.widget.Button;
import android.widget.Toast;

public class Activity_Dialog extends Activity implements OnClickListener {
    private Button btn_dialog;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_dialog);
        btn_dialog = (Button) findViewById(R.id.btn_dialog);
        btn_dialog.setOnClickListener(this);
    }

    @Override
    public void onClick(View arg0) {
        // TODO Auto-generated method stub
        switch (arg0.getId()) {
        case R.id.btn_dialog:
            initDialog();
            break;

        default:
            break;
        }
    }

    private void initDialog() {
        // TODO Auto-generated method stub
        AlertDialog.Builder builder = new AlertDialog.Builder(this);
        builder.setCancelable(false);
        final AlertDialog dialog = builder.create();
        View view = View.inflate(this, R.layout.item_dialog, null);
        dialog.setView(view, 0, 0, 0, 0);
        Button btnCancel = (Button) view.findViewById(R.id.btn_cancel);
        Button btnOk = (Button) view.findViewById(R.id.btn_ok);
        btnOk.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                Toast.makeText(Activity_Dialog.this, "queding",
                        Toast.LENGTH_SHORT).show();
                dialog.dismiss();
            }
        });
        btnCancel.setOnClickListener(new View.OnClickListener() {

            @Override
            public void onClick(View arg0) {
                // TODO Auto-generated method stub
                dialog.dismiss();
            }
        });
        dialog.show();
        /**
         * 改變Dialog在屏幕顯示的位置
         */
        WindowManager manager = getWindowManager();
        Display display = manager.getDefaultDisplay();
        android.view.WindowManager.LayoutParams params = dialog.getWindow()
                .getAttributes();
        params.height = (int) (display.getHeight() * 0.4);
        params.width = (int) (display.getWidth() * 0.75);
        params.x = 10;
        params.y = 150;
        dialog.getWindow().setAttributes(params);
    }

}
