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());
