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
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);
}
});
}
}
