一、效果图如下
在开发的时候，有时需要可控的显示和隐藏输入框，下面是自己写的demo，贴出来共享
activity_update_password.xml
<?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" > <include layout="@layout/titlebar_update_password" /> <LinearLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:orientation="vertical" android:padding="2dp" > <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:layout_marginTop="5dp" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:text="@string/Current_Password" /> <TextView android:id="@+id/activity_update_show01" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_marginTop="5dp" android:clickable="true" android:onClick="showPassword" android:padding="5dp" android:text="@string/Show_Password" android:textColor="@drawable/read_more_btn" android:textSize="10sp" /> </RelativeLayout> <EditText android:id="@+id/activity_update_currentPassword" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="10dp" android:background="@android:drawable/edit_text" android:hint="@string/Current_Password" android:singleLine="true" android:textColor="#000000" android:inputType="textPassword" android:textCursorDrawable="@null" /> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:layout_marginTop="5dp" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:text="@string/New_Password" /> <TextView android:id="@+id/activity_update_show02" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_marginTop="5dp" android:clickable="true" android:onClick="showPassword" android:padding="5dp" android:text="@string/Show_Password" android:textColor="@drawable/read_more_btn" android:textSize="10sp" /> </RelativeLayout> <EditText android:id="@+id/activity_update_newPassword" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="10dp" android:background="@android:drawable/edit_text" android:hint="@string/New_Password" android:singleLine="true" android:textColor="#000000" android:inputType="textPassword" android:textCursorDrawable="@null" /> <RelativeLayout android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginLeft="5dp" android:layout_marginRight="5dp" android:layout_marginTop="5dp" > <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentLeft="true" android:text="@string/confirm_password" /> <TextView android:id="@+id/activity_update_show03" android:layout_width="wrap_content" android:layout_height="wrap_content" android:layout_alignParentRight="true" android:layout_marginTop="5dp" android:clickable="true" android:onClick="showPassword" android:padding="5dp" android:text="@string/Show_Password" android:textColor="@drawable/read_more_btn" android:textSize="10sp" /> </RelativeLayout> <EditText android:id="@+id/activity_update_confirmPassword" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="10dp" android:background="@android:drawable/edit_text" android:hint="@string/confirm_password" android:singleLine="true" android:textColor="#000000" <span style="color:#ff6666;"> android:inputType="textPassword"</span> android:textCursorDrawable="@null" /> <Button android:id="@+id/activity_update_updatePassword" android:layout_width="match_parent" android:layout_height="wrap_content" android:layout_marginTop="10dp" android:background="@drawable/theme_btn" android:text="@string/Update_Password" /> </LinearLayout></LinearLayout>Update按钮点击效果
<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:drawable="@drawable/theme_blue_normal" android:state_enabled="true" android:state_window_focused="false"/> <item android:drawable="@drawable/theme_blue_normal" android:state_enabled="false"/> <item android:drawable="@drawable/theme_blue_press" android:state_pressed="true"/> <item android:drawable="@drawable/theme_blue_normal" android:state_focused="true"/></selector>
需要提供2张图片背景即可，即点击前后的背景图片
文字点击效果<?xml version="1.0" encoding="utf-8"?><selector xmlns:android="http://schemas.android.com/apk/res/android"> <item android:state_pressed="true" android:color="#f00"/> <item android:state_focused="true" android:color="@color/activity_search_title_bg"/> <item android:color="@color/activity_search_title_bg"/></selector>需要2种颜色，即点击前后的文字颜色
