效果：

<?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" > <EditText android:id="@+id/editText1" android:layout_width="match_parent" android:layout_height="wrap_content" android:ems="10" android:inputType="textPassword" > <requestFocus /> </EditText> <CheckBox android:id="@+id/checkBox1" android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="显示密码" /></LinearLayout>package com.example.test;import android.app.Activity;import android.os.Bundle;import android.text.method.HideReturnsTransformationMethod;import android.text.method.PasswordTransformationMethod;import android.widget.CheckBox;import android.widget.CompoundButton;import android.widget.CompoundButton.OnCheckedChangeListener;import android.widget.TextView;public class MainActivity extends Activity {private TextView editText1;private CheckBox checkBox1; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.test); editText1 =(TextView) findViewById(R.id.editText1); checkBox1=(CheckBox) findViewById(R.id.checkBox1); checkBox1.setOnCheckedChangeListener(new OnCheckedChangeListener() { @Override public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) { // TODO Auto-generated method stub if(isChecked){ //如果选中，显示密码 editText1.setTransformationMethod(HideReturnsTransformationMethod.getInstance()); }else{ //否则隐藏密码 editText1.setTransformationMethod(PasswordTransformationMethod.getInstance()); } } }); }}

关键是：

editText1.setTransformationMethod(HideReturnsTransformationMethod.getInstance());editText1.setTransformationMethod(PasswordTransformationMethod.getInstance());
