Android中自定义底部弹出框ButtomDialog

先看看效果和你要的是否一样

一、先来配置自定义控件需要的资源。

1.在res文件夹下创建一个anim文件夹并创建两个slide_in_bottom.xml、slide_out_bottom.xml文件，负责弹框进出动画。

<?xml version="1.0" encoding="utf-8"?>

<?xml version="1.0" encoding="utf-8"?>

2.在style.xml添加阴影和动画样式。

3.在drawable文件夹下创建一个title_background.xml文件，负责给文本内容添加背景。

<?xml version="1.0" encoding="UTF-8"?>

二、自定义控件的布局。

三、自定义控件类。

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).inflate(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(50,0,50,0);            int dip1 = (int) (1 * p.context.getResources().getDisplayMetrics().density + 0.5f);            int spacing = dip1 * 12;            boolean hasTitle = !TextUtils.isEmpty(p.menuTitle);            if (hasTitle) {                //标题样式                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);                //单独给标题设置背景样式//                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);            }            //每一条的样式            for (int i = 0; i < p.menuList.size(); i++) {                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;        }    }}

四、使用。

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);                //添加条目，可多个                builder.addMenu("相机", new View.OnClickListener() {                    @Override                    public void onClick(View view) {                        dialog.cancel();                        Toast.makeText(MainActivity.this, "相机", Toast.LENGTH_SHORT).show();                    }                }).addMenu("相册", new View.OnClickListener() {                    @Override                    public void onClick(View view) {                        dialog.cancel();                        Toast.makeText(MainActivity.this, "相册", Toast.LENGTH_SHORT).show();                    }                });                //下面这些设置都可不写                builder.setTitle("这是标题");//添加标题                builder.setCanCancel(false);//点击阴影时是否取消dialog，true为取消                builder.setShadow(true);//是否设置阴影背景，true为有阴影                builder.setCancelText("取消");//设置最下面取消的文本内容                //设置点击取消时的事件                builder.setCancelListener(new View.OnClickListener() {                    @Override                    public void onClick(View view) {                        dialog.cancel();                        Toast.makeText(MainActivity.this, "取消", Toast.LENGTH_SHORT).show();                    }                });                dialog = builder.create();                dialog.show();                break;            default:                break;        }    }}
