Android--创建进度框ProgressDialog

1、布局文件progress_dialog_activity.xml

<?xml version="1.0" encoding="utf-8"?>

<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"

    android:layout_width="match_parent"

    android:layout_height="match_parent"

    android:orientation="vertical" >

    

    <Button 

        android:id="@+id/btn_progress_dialog"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:text="@string/btn_progress_dialog_text"

        android:layout_gravity="center_horizontal"/>

</LinearLayout>

 

2、Activity类ProgressDialogActivity.java

package cn.luxh.dialognew;



import android.app.Activity;

import android.app.ProgressDialog;

import android.os.Bundle;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;



public class ProgressDialogActivity extends Activity {

    

    private Button btn_progress_dialog;

    

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.progress_dialog_activity);

        handleBtnProgressDialogClick();

    }

    

    /**

     * 处理按钮事件

     */

    private void handleBtnProgressDialogClick() {

        btn_progress_dialog = (Button) findViewById(R.id.btn_progress_dialog);

        btn_progress_dialog.setOnClickListener(new OnClickListener() {

            @Override

            public void onClick(View v) {

                createProgressDialog();

            }

        });

    }

    

    /**

     * 生成进度对话框

     */

    private void createProgressDialog() {

        //显示进度对话框

        final ProgressDialog progressDialog = ProgressDialog.show(this, "提示", "处理中..."); 

        

        //业务处理

        new Thread(new Runnable(){

            @Override

            public void run() {

                try {

                    Thread.sleep(10000);

                    progressDialog.dismiss();//取消进度对话框

                } catch (InterruptedException e) {

                    e.printStackTrace();

                }

            }

        }).start();

    }

    

    

}

　　一个带实时进度的对话框

代码如下：

package cn.luxh.dialognew;



import android.app.Activity;

import android.app.ProgressDialog;

import android.content.DialogInterface;

import android.os.Bundle;

import android.util.Log;

import android.view.View;

import android.view.View.OnClickListener;

import android.widget.Button;

import android.widget.Toast;



public class ProgressDialogActivity extends Activity {

    

    private Button btn_progress_dialog;

    

    private ProgressDialog progressDialog;

    

    private static final String TAG = "ProgressDialogActivity";

    

    //控制线程中断

    private static boolean isRun = true;

    

    @Override

    protected void onCreate(Bundle savedInstanceState) {

        super.onCreate(savedInstanceState);

        setContentView(R.layout.progress_dialog_activity);

        handleBtnProgressDialogClick();

    }

    

    /**

     * 处理按钮事件

     */

    private void handleBtnProgressDialogClick() {

        btn_progress_dialog = (Button) findViewById(R.id.btn_progress_dialog);

        btn_progress_dialog.setOnClickListener(new OnClickListener() {

            @Override

            public void onClick(View v) {

                isRun = true;

                createProgressDialog2();

                progressDialog.show();

                progressDialog.setProgress(0);

                new Thread(new Runnable(){

                    @Override

                    public void run() {

                        int i = 1;

                        while(isRun && i<=20) {

                            try {

                                Log.d(TAG, "i is:"+i);

                                Thread.sleep(1500);

                                progressDialog.incrementProgressBy(100/20);

                                i++;

                            } catch (InterruptedException e) {

                                isRun = false;//中断线程

                                e.printStackTrace();

                            }

                        }

                    }

                }).start();

            }

        });

    }

    

    /**

     * 生成进度对话框

     */

    private void createProgressDialog2() {

        progressDialog = new ProgressDialog(this);

        progressDialog.setIcon(R.drawable.ic_launcher);

        progressDialog.setTitle("实时进度...");

        progressDialog.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);

        progressDialog.setCancelable(false);//设置模态窗口

        progressDialog.setButton(ProgressDialog.BUTTON_POSITIVE, "确定", new DialogInterface.OnClickListener() {

            @Override

            public void onClick(DialogInterface dialog, int which) {

                isRun = false;//中断线程

                Toast.makeText(getBaseContext(), "确定按钮被点击！", Toast.LENGTH_SHORT).show();

            }

        });

        progressDialog.setButton(ProgressDialog.BUTTON_NEGATIVE, "取消", new DialogInterface.OnClickListener() {

            @Override

            public void onClick(DialogInterface dialog, int which) {

                isRun = false;//中断线程

                Toast.makeText(getBaseContext(), "取消按钮被点击！", Toast.LENGTH_SHORT).show();

            }

        });
