Android 小控件使用合集

冒泡排序

public class bubbleSort {  public  bubbleSort(){       int a[]={49,38,65,97,**,**,**,**,78,34,12,64,5,4,62,99,98,54,56,17,18,23,34,15,35,25,53,51};      int temp=0;      for(int i=0;i<a.length-1;i++){          for(int j=0;j<a.length-1-i;j++){          if(a[j]>a[j+1]){              temp=a[j];              a[j]=a[j+1];              a[j+1]=temp;          }          }      }      for(int i=0;i<a.length;i++)      System.out.println(a[i]);     }  } 

popupwindow

public void popwindow(){        v = View.inflate(context, R.layout.item_cha,null);        pop = new PopupWindow(v, ViewGroup.LayoutParams.WRAP_CONTENT, ViewGroup.LayoutParams.WRAP_CONTENT, true);        // 设置PopupWindow的背景        pop.setBackgroundDrawable(new ColorDrawable(Color.YELLOW));        // 设置PopupWindow是否能响应外部点击事件        pop.setOutsideTouchable(true);        // 设置PopupWindow是否能响应点击事件        pop.setTouchable(true);    }点击控件显示popupwindow ImageView cha2=(ImageView) convertView.findViewById(R.id.cha2);            cha2.setOnClickListener(new View.OnClickListener() {                @Override                public void onClick(View view) {                    popwindow();                    pop.showAsDropDown(view);                    final Button btnquxiao=(Button) v.findViewById(R.id.quxiao);                    btnquxiao.setOnClickListener(new View.OnClickListener() {                        @Override                        public void onClick(View view) {                            pop.dismiss();                        }                    });

ActionBar

ActionBar mActionBar=getSupportActionBar();mActionBar.setHomeButtonEnabled(true);mActionBar.setDisplayHomeAsUpEnabled(true);mActionBar.setTitle("设置");

夜间模式

public void yejian(){        int mode = getResources().getConfiguration().uiMode & Configuration.UI_MODE_NIGHT_MASK;        if(mode == Configuration.UI_MODE_NIGHT_YES) {            AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_NO);        } else if(mode == Configuration.UI_MODE_NIGHT_NO) {            AppCompatDelegate.setDefaultNightMode(AppCompatDelegate.MODE_NIGHT_YES);        } else {            // blah blah        }        recreate();    }

新建夜间模式资源文件夹:在res目录下新建values-night文件夹，然后在此目录下新建colors.xml文件在夜间模式下的应用的资源。当然也可以根据需要新建drawable-night,layout-night等后缀为-night的夜间资源文件夹。
我的values和values-night目录下的colors.xml的内容如下:

<?xml version="1.0" encoding="utf-8"?> <resources>     <color name="colorPrimary">#35464e</color>     <color name="colorPrimaryDark">#212a2f</color>     <color name="colorAccent">#212a2f</color>     <color name="textColorPrimary">#616161</color>     <color name="viewBackground">#212a2f</color> </resources>

让我们自己的主题继承并应用DayNight主题。

<style name="AppTheme" parent="Theme.AppCompat.DayNight.DarkActionBar">         <item name="colorPrimary">@color/colorPrimary</item>         <item name="colorPrimaryDark">@color/colorPrimaryDark</item>         <item name="colorAccent">@color/colorAccent</item>         <!--customize your theme here--> </style>

短信验证 我用的是mob首先去mob官网下载smsssdk，下载完之后会有俩文件夹
点击这个是mob网址

之后是打开

在完后就是

下面是代码展示

public class MainActivity extends AppCompatActivity {    private EditText editphone;    private EditText edityanzheng;    private Button btnhuoqu;    private Button btnyanzheng;    @Override    protected void onCreate(Bundle savedInstanceState) {        super.onCreate(savedInstanceState);

                   }                });            }        });        btnyanzheng.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View view) {                SMSSDK.submitVerificationCode("86", editphone.getText().toString().trim(), edityanzheng.getText().toString().trim());
