通过EditText填写同时进度条发生改变

最近，在项目里面需要实现一个功能，就是通过我填写资料多少我的进度条发生改变（话不多说，下面来看代码 ）

主要代码实现：

package com.quincy.changeeditetext;

import android.app.Activity;

import android.os.Bundle;

import android.text.Editable;

import android.text.TextWatcher;

import android.widget.EditText;

import android.widget.ProgressBar;

public class MainActivity extends Activity {

private int progress = 0;

private ProgressBar pb;

private EditText one;

private EditText two;

private EditText three;

private EditText fore;

private EditText five;

private boolean flag1 = true;

private boolean flag2 = true;

private boolean flag3 = true;

private boolean flag4 = true;

private boolean flag5 = true;

点击打开链接点击打开链接

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

one = (EditText) findViewById(R.id.one);

two = (EditText) findViewById(R.id.two);

three = (EditText) findViewById(R.id.three);

fore = (EditText) findViewById(R.id.fore);

five = (EditText) findViewById(R.id.five);

// 为EditText绑定监听器

one.addTextChangedListener(new textChange(flag1));点击打开链接

two.addTextChangedListener(new textChange(flag2));

three.addTextChangedListener(new textChange(flag3));

fore.addTextChangedListener(new textChange(flag4));

five.addTextChangedListener(new textChange(flag5));

pb = (ProgressBar) findViewById(R.id.pb);

}

class textChange implements TextWatcher {

private boolean flag;

public textChange(boolean flag) {

this.flag = flag;

}

@Override

public void afterTextChanged(Editable s) {

}

@Override

public void beforeTextChanged(CharSequence s, int start, int count, int after) {

}

@Override

public void onTextChanged(CharSequence s, int start, int before, int count) {

if (s.length() > 0 && flag) {

progress += 20;

flag = false;

}

if (s.length() == 0) {

flag = true;

progress -= 20;

}

pb.setProgress(progress);

}

}

}

这样就可以通过edittext的填写内容我的progressbar就可以发生改变了，是不是很简单，赶快应用的你们的项目中来吧。
