在res下面创建一个menu文件夹,并新建一个xml文件作为OptionMenu的布局文件
<menu xmlns:android="http://schemas.android.com/apk/res/android">
<item android:id="@+id/blue" android:title="蓝色"></item>
<item android:id="@+id/red" android:title="红色"></item>
<item android:id="@+id/other" android:title="其他颜色">
<menu>
<item android:id="@+id/white" android:title="白色"></item>
<item android:id="@+id/green" android:title="绿色"></item>
</menu>
</item>
</menu>
Activity重写onCreateOptionsMenu加载资源文件
Activity重写onOptionsItemSelected加设置事件监听
//Activity重写onCreateOptionsMenu加载资源文件 @Override public boolean onCreateOptionsMenu(Menu menu) { getMenuInflater().inflate(R.menu.menu,menu); return super.onCreateOptionsMenu(menu); } //Activity重写onOptionsItemSelected设置事件监听 @Override public boolean onOptionsItemSelected(MenuItem item) { int itemId = item.getItemId(); switch (itemId){ case R.id.blue: Toast.makeText(this, "蓝色", Toast.LENGTH_SHORT).show(); break; case R.id.red: Toast.makeText(this, "红色", Toast.LENGTH_SHORT).show(); break; case R.id.white: Toast.makeText(this,item.getTitle(), Toast.LENGTH_SHORT).show(); break; case R.id.green: Toast.makeText(this,item.getTitle(), Toast.LENGTH_SHORT).show(); break; } return super.onOptionsItemSelected(item); }
步骤流程:
在res下面创建一个menu文件夹,新建一个xml文件作为ContextMenu的布局文件,复用上面的menu布局
protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main2); text = (TextView) findViewById(R.id.text); //为控件添加长按属性并将菜单绑定到这个控件上 registerForContextMenu(text); } @Override public void onCreateContextMenu(ContextMenu menu, View v, ContextMenu.ContextMenuInfo menuInfo) { getMenuInflater().inflate(R.menu.menu,menu); super.onCreateContextMenu(menu, v, menuInfo); } @Override public boolean onContextItemSelected(MenuItem item) { int itemId = item.getItemId(); switch (itemId){ case R.id.blue: Toast.makeText(this, "蓝色", Toast.LENGTH_SHORT).show(); break; case R.id.red: Toast.makeText(this, "红色", Toast.LENGTH_SHORT).show(); break; case R.id.white: Toast.makeText(this,item.getTitle(), Toast.LENGTH_SHORT).show(); break; case R.id.green: Toast.makeText(this,item.getTitle(), Toast.LENGTH_SHORT).show(); break; } return super.onContextItemSelected(item); }
在res下面创建一个menu文件夹,并新建一个xml文件作为PoupMenu的布局文件。
<?xml version="1.0" encoding="utf-8"?> <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:app="http://schemas.android.com/apk/res-auto" xmlns:tools="http://schemas.android.com/tools" android:layout_width="match_parent" android:layout_height="match_parent" tools:context=".Main2Activity" android:gravity="center"> <TextView android:id="@+id/popup_tv" android:text="弹出菜单" android:layout_width="wrap_content" android:layout_height="wrap_content" /> </LinearLayout> private TextView text; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.activity_main3); text = (TextView) findViewById(R.id.textid); text.setOnClickListener(new View.OnClickListener() { @Override public void onClick(View v) { showPopupMenu(); } }); }
public void showPopupMenu(){ //参数一 上下文 参数二 菜单显示在指定控件的下方 PopupMenu popupMenu = new PopupMenu(this, text); //记载布局 popupMenu.inflate(R.menu.menu); //事件监听 popupMenu.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() { @Override public boolean onMenuItemClick(MenuItem item) { int itemId = item.getItemId(); switch (itemId){ case R.id.blue: Toast.makeText(Main3Activity.this, "蓝色", Toast.LENGTH_SHORT).show(); break; case R.id.red: Toast.makeText(Main3Activity.this, "红色", Toast.LENGTH_SHORT).show(); break; case R.id.white: Toast.makeText(Main3Activity.this,item.getTitle(), Toast.LENGTH_SHORT).show(); break; case R.id.green: Toast.makeText(Main3Activity.this,item.getTitle(), Toast.LENGTH_SHORT).show(); break; } return false; } }); popupMenu.show(); }
PopupWindow
PopupWindow弹出窗体可以在任意位置弹出窗体,而对话框只能出现屏幕最中间。
(1)构造方法:public PopupWindow (Context context):context上下文对象
(2)必须设置的3大要素:
setContentView():设置自定义布局
setWidth():设置宽度
setHeight():设置高度
(3)显示窗体:
a。显示在某个指定控件的下方
showAsDropDown(View anchor):
showAsDropDown(View anchor, int xoff, int yoff);//xoff和yoff都是偏移量
b。指定父视图,显示在父控件的某个位置(Gravity.TOP,Gravity.RIGHT等)
showAtLocation(View parent, int gravity, int x, int y);
//gravity可以是Gravity.TOP、Gravity.BOTTOM、Gravity.LEFT、Gravity.RIGHT

1.在res/anim文件夹下定义进场动画
duration:动画时长
<translate
android:duration="2000"
android:fromYDelta="0"
android:toYDelta="100%" />
<translate
android:duration="2000"
android:fromYDelta="100%"
android:toYDelta="0" />
2.定义进出场动画
<style name="MyPopupWindow">
<item name="android:windowEnterAnimation">@anim/pop_in</item>
<item name="android:windowExitAnimation">@anim/pop_out</item>
</style>
setAnimationStyle(R.style.MyPopupWindow);
public class MyPopupWindow extends PopupWindow { Context mContext; private LayoutInflater mInflater; private View mContentView; public MyPopupWindow(Context context) { super(context); this.mContext=context; //打气筒 mInflater = (LayoutInflater) context.getSystemService(Context.LAYOUT_INFLATER_SERVICE); //打气 mContentView = mInflater.inflate(R.layout.layout_dialog,null); //设置View setContentView(mContentView); //设置宽与高 setWidth(WindowManager.LayoutParams.MATCH_PARENT); setHeight(WindowManager.LayoutParams.WRAP_CONTENT); /** * 设置进出动画 */ setAnimationStyle(R.style.MyPopupWindow); /** * 设置背景只有设置了这个才可以点击外边和BACK消失 */ setBackgroundDrawable(new ColorDrawable()); /** * 设置可以获取集点 */ setFocusable(true); /** * 设置点击外边可以消失 */ setOutsideTouchable(true); /** *设置可以触摸 */ setTouchable(true); /** * 设置点击外部可以消失 */ setTouchInterceptor(new View.OnTouchListener() { @Override public boolean onTouch(View v, MotionEvent event) { /** * 判断是不是点击了外部 */ if(event.getAction()==MotionEvent.ACTION_OUTSIDE){ return true; } //不是点击外部 return false; } }); /** * 初始化View与监听器 */ initView(); initListener(); } private void initView() { } private void initListener() { } }
