1、效果图

2、布局文件

<?xml version="1.0" encoding="utf-8"?><RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"    xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent"    android:layout_height="match_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="wifi.app.wei.com.myapplication.MainActivity">    <RelativeLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:padding="10dp"        >        <ImageView            android:id="@+id/image"            android:layout_width="wrap_content"            android:layout_height="wrap_content"            android:src="@mipmap/eye_close"            android:layout_alignParentRight="true"            android:layout_centerVertical="true"            />        <EditText            android:id="@+id/pass_et"            android:layout_toLeftOf="@id/image"            android:layout_width="match_parent"            android:layout_height="wrap_content"            android:inputType="textPassword"            />    </RelativeLayout></RelativeLayout>

3、代码实现（方式一）

package wifi.app.wei.com.myapplication;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.text.InputType;import android.view.View;import android.widget.EditText;import android.widget.ImageView;public class MainActivity extends AppCompatActivity {    private ImageView imageView ;    private EditText editText ;    boolean eyeOpen = false ;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main );        imageView = (ImageView) findViewById( R.id.image) ;        editText = (EditText) findViewById( R.id.pass_et);        imageView.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                if ( eyeOpen ){                    //密码 TYPE_CLASS_TEXT 和 TYPE_TEXT_VARIATION_PASSWORD 必须一起使用                    editText.setInputType(InputType.TYPE_CLASS_TEXT | InputType.TYPE_TEXT_VARIATION_PASSWORD);                    imageView.setImageResource( R.mipmap.eye_close );                    eyeOpen = false ;                }else {                    //明文                    editText.setInputType( InputType.TYPE_TEXT_VARIATION_VISIBLE_PASSWORD );                    imageView.setImageResource( R.mipmap.eye_open );                    eyeOpen = true ;                }            }        });    }}

package wifi.app.wei.com.myapplication;import android.os.Bundle;import android.support.v7.app.AppCompatActivity;import android.text.method.HideReturnsTransformationMethod;import android.text.method.PasswordTransformationMethod;import android.view.View;import android.widget.EditText;import android.widget.ImageView;public class MainActivity extends AppCompatActivity {    private ImageView imageView ;    private EditText editText ;    boolean eyeOpen = false ;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);        setContentView(R.layout.activity_main );        imageView = (ImageView) findViewById( R.id.image) ;        editText = (EditText) findViewById( R.id.pass_et);        imageView.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                if ( eyeOpen ){                    //密码                    editText.setTransformationMethod(PasswordTransformationMethod.getInstance());                    imageView.setImageResource( R.mipmap.eye_close );                    eyeOpen = false ;                }else {                    //明文                    editText.setTransformationMethod(HideReturnsTransformationMethod.getInstance());                    imageView.setImageResource( R.mipmap.eye_open );                    eyeOpen = true ;                }            }        });    }}
