two。 Add shadows and animation styles to style.xml.

@ android:color/transparent true true @ null false @ anim/slide_in_bottom @ anim/slide_out_bottom

3. Create a title_background.xml file under the drawable folder that is responsible for adding background to the text content.

Second, customize the layout of controls

III. Custom control class

Public class ButtomDialog extends Dialog {public ButtomDialog (Context context, int themeResId) {super (context, themeResId);} public static class Params {private final List menuList = new ArrayList (); private View.OnClickListener cancelListener; private CharSequence menuTitle; private String cancelText; private Context context;} public static class Builder {private boolean canCancel = true; private boolean shadow = true; private final Params p; public Builder (Context context) {p = new Params () P.context = context;} public Builder setCanCancel (boolean canCancel) {this.canCancel = canCancel; return this;} public Builder setShadow (boolean shadow) {this.shadow = shadow; return this;} public Builder setTitle (CharSequence title) {this.p.menuTitle = title; return this;} public Builder addMenu (String text, View.OnClickListener listener) {BottomMenu bm = new BottomMenu (text, listener) This.p.menuList.add (bm); return this;} public Builder addMenu (int textId, View.OnClickListener listener) {return addMenu (p.context.getString (textId), listener);} public Builder setCancelListener (View.OnClickListener cancelListener) {p.cancelListener = cancelListener; return this;} public Builder setCancelText (int resId) {p.cancelText = p.context.getString (resId); return this } public Builder setCancelText (String text) {p.cancelText = text; return this;} public ButtomDialog create () {final ButtomDialog dialog = new ButtomDialog (p.context, shadow? R.style.Theme_Light_NoTitle_Dialog: R.style.Theme_Light_NoTitle_NoShadow_Dialog); Window window = dialog.getWindow (); window.setWindowAnimations (R.style.Animation_Bottom_Rising); window.getDecorView (). SetPadding (0,0,0,0); WindowManager.LayoutParams lp = window.getAttributes (); lp.width = WindowManager.LayoutParams.MATCH_PARENT; lp.height = WindowManager.LayoutParams.WRAP_CONTENT; window.setAttributes (lp) Window.setGravity (Gravity.BOTTOM); View view = LayoutInflater.from (p.context). Evaluate (R.layout.dialog_bottom_menu, null); TextView btnCancel = (TextView) view.findViewById (R.id.btn_cancel); ViewGroup layContainer = (ViewGroup) view.findViewById (R.id.lay_container); ViewGroup.LayoutParams lpItem = new ViewGroup.LayoutParams (ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT) ViewGroup.MarginLayoutParams lpDivider = new ViewGroup.MarginLayoutParams (ViewGroup.LayoutParams.MATCH_PARENT, 1); lpDivider.setMargins (50 p.context.getResources (). GetDisplayMetrics (). Density + 0.5f); int spacing = dip1 * 12; boolean hasTitle =! TextUtils.isEmpty (p.menuTitle); if (hasTitle) {/ / title style TextView tTitle = new TextView (p.context) TTitle.setLayoutParams (lpItem); tTitle.setGravity (Gravity.CENTER); tTitle.setTextColor (p.context.getResources (). GetColor (R.color.colorAccent)); tTitle.setText (p.menuTitle); tTitle.setPadding (0, spacing, 0, spacing); / / set the background style for the title separately / / tTitle.setBackgroundResource (R.drawable.common_dialog_selection_selector_top) LayContainer.addView (tTitle); View viewDivider = new View (p.context); viewDivider.setLayoutParams (lpDivider); viewDivider.setBackgroundColor (0xFFCED2D6); layContainer.addView (viewDivider);} / / the style for of each item (int I = 0; I < p.menuList.size (); iTunes +) {BottomMenu bottomMenu = p.menuList.get (I); TextView bbm = new TextView (p.context) Bbm.setLayoutParams (lpItem); bbm.setPadding (0, spacing, 0, spacing); bbm.setGravity (Gravity.CENTER); bbm.setText (bottomMenu.funName); bbm.setTextColor (0xFF007AFF); bbm.setTextSize (16); bbm.setOnClickListener (bottomMenu.listener); layContainer.addView (bbm) If (I! = p.menuList.size ()-1) {View viewDivider = new View (p.context); viewDivider.setLayoutParams (lpDivider); viewDivider.setBackgroundColor (0xFFCED2D6); layContainer.addView (viewDivider);}} if (! TextUtils.isEmpty (p.cancelText)) {btnCancel.setText (p.cancelText) } if (p.cancelListener! = null) {btnCancel.setOnClickListener (p.cancelListener);} else {btnCancel.setOnClickListener (new View.OnClickListener () {@ Override public void onClick (View v) {dialog.dismiss ();}});} dialog.setContentView (view); dialog.setCanceledOnTouchOutside (canCancel); dialog.setCancelable (canCancel) Return dialog;}} private static class BottomMenu {public String funName; public View.OnClickListener listener; public BottomMenu (String funName, View.OnClickListener listener) {this.funName = funName; this.listener = listener;}

IV. Use

Public class MainActivity extends AppCompatActivity implements View.OnClickListener {private Button mDialogCustom; private ButtomMenuDialog dialog; @ Override protected void onCreate (Bundle savedInstanceState) {super.onCreate (savedInstanceState); setContentView (R.layout.activity_main); initView ();} private void initView () {mDialogCustom = (Button) findViewById (R.id.custom_dialog); mDialogCustom.setOnClickListener (this) } @ Override public void onClick (View v) {switch (v.getId ()) {case R.id.custom_dialog: ButtomMenuDialog.Builder builder = new ButtomMenuDialog.Builder (this); / / add multiple builder.addMenu ("camera", new View.OnClickListener () {@ Override public void onClick (View view) {dialog.cancel ()) Toast.makeText (MainActivity.this, "camera", Toast.LENGTH_SHORT). Show ();}}) .addMenu ("album", new View.OnClickListener () {@ Override public void onClick (View view) {dialog.cancel (); Toast.makeText (MainActivity.this, "album", Toast.LENGTH_SHORT) .show () }}); / / the following settings can not write builder.setTitle ("this is the title"); / / add the title builder.setCanCancel (false); / / whether to cancel the dialog,true when clicking the shadow is to cancel the builder.setShadow (true); / / whether to set the shadow background, true is the shadow builder.setCancelText ("cancel") / / set the text content cancelled at the bottom / / set the event builder.setCancelListener when you click cancel (new View.OnClickListener () {@ Override public void onClick (View view) {dialog.cancel (); Toast.makeText (MainActivity.this, "cancel", Toast.LENGTH_SHORT). Show ();}}) Dialog = builder.create (); dialog.show (); break; default: break;} this is the end of the study on "how to use ButtomDialog to customize the bottom pop-up box in Android", hoping to solve everyone's doubts.
