本文实例为大家分享了Android实现带有进度条按钮效果的具体代码，供大家参考，具体内容如下

安卓中带有进度条效果的按钮，如下图：

1.布局文件如下activity_main.xml

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:tools="http://schemas.android.com/tools" android:layout_width="fill_parent" android:layout_height="fill_parent" android:paddingBottom="@dimen/activity_vertical_margin" android:paddingLeft="@dimen/activity_horizontal_margin" android:paddingRight="@dimen/activity_horizontal_margin" android:paddingTop="@dimen/activity_vertical_margin" tools:context=".MainActivity" > <TextView android:id="@+id/text" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="带有进度条的Button" /> <RelativeLayout android:layout_width="fill_parent" android:layout_height="50dp" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:gravity="bottom" > <ProgressBar android:id="@+id/progressBar" style="?android:attr/progressBarStyleHorizontal" android:layout_width="fill_parent" android:layout_height="fill_parent" android:background="@drawable/aa_button_gray_normal" android:max="100" android:progress="0" android:progressDrawable="@drawable/progress_selector" /> <Button android:id="@+id/downLoadBtn" android:layout_width="fill_parent" android:layout_height="fill_parent" android:layout_centerHorizontal="true" android:layout_centerVertical="true" android:background="@drawable/btn_selector" android:text="下载" /> </RelativeLayout> </RelativeLayout>

2.java主界面代码如下：MainActivity.java

package com.example.buttondemo; import android.app.Activity;import android.os.Bundle;import android.os.Handler;import android.os.Message;import android.view.View;import android.widget.Button;import android.widget.ProgressBar;import android.widget.TextView; public class MainActivity extends Activity { int i = 0; ProgressBar progressBar = null; Button downLoadBtn = null; Handler handler = new Handler() { public void handleMessage(android.os.Message msg) { switch (msg.what) { case 1: i += 5; progressBar.setProgress(i); if (i != 100) { handler.sendEmptyMessageDelayed(new Message().what = 1, 500); downLoadBtn.setText(i + "%"); } else if (i == 100) { downLoadBtn.setText("下载完成"); // 进度条运行完成时按钮可用 downLoadBtn.setEnabled(true); } break; default: break; } }; }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main); TextView tx = (TextView) findViewById(R.id.text); progressBar = (ProgressBar) findViewById(R.id.progressBar); downLoadBtn = (Button) findViewById(R.id.downLoadBtn); downLoadBtn.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { i = 0; handler.sendEmptyMessage(new Message().what = 1); // 进度条运行时按钮不可用 downLoadBtn.setEnabled(false); } }); } }
