android对话框底部显示,Android实现底部弹出的对话框功能

环境：

主机:WIN10

开发环境:Android Studio 2.2 Preview 3

说明：

两种方法实现底部弹出的对话框：

Dialog

DialogFragment

推荐用DialogFragment

效果图：

布局文件dialog_select_call.xml：

android:orientation="vertical" android:layout_width="match_parent"

android:layout_height="match_parent">

android:id="@+id/layout_voice"

android:layout_width="match_parent"

android:layout_height="wrap_content"

Dialog实现源码：

初始化：

private void dialogSelectCallInit() {

dialogSelectCall = new Dialog(this, R.style.DialogPopBottom);

View inflate = LayoutInflater.from(this).inflate(R.layout.dialog_select_call, null);

dialogSelectCall.setContentView(inflate);

Window dialogWindow = dialogSelectCall.getWindow();

dialogWindow.setGravity(Gravity.BOTTOM);

WindowManager.LayoutParams lp = dialogWindow.getAttributes();

lp.x = 0;

lp.y = 0;

lp.width = getResources().getDisplayMetrics().widthPixels;

dialogWindow.setAttributes(lp);

RelativeLayout layoutVoice = (RelativeLayout) inflate.findViewById(R.id.layout_voice);

RelativeLayout layoutVideo = (RelativeLayout) inflate.findViewById(R.id.layout_video);

Button buttonCancel = (Button) inflate.findViewById(R.id.cancel);

RxView.clicks(layoutVoice)

.throttleFirst(2, TimeUnit.SECONDS)

.compose(this.bindUntilEvent(ActivityEvent.DESTROY))

.subscribe(v -> {

// dialogSelectCall.cancel();

VoiceSessionActivity.startActivityCallOut(this, userId);

});

RxView.clicks(layoutVideo)

.throttleFirst(2, TimeUnit.SECONDS)

.compose(this.bindUntilEvent(ActivityEvent.DESTROY))

.subscribe(v -> {

// dialogSelectCall.cancel();

// VideoSessionActivity.startActivityCallOut(this, userId);

});

RxView.clicks(buttonCancel)

.throttleFirst(2, TimeUnit.SECONDS)

.compose(this.bindUntilEvent(ActivityEvent.DESTROY))

.subscribe(v -> dialogSelectCall.cancel());

RxView.touches(layoutVoice, motionEvent -> {

dealLayoutTouch(layoutVoice, motionEvent);

return false;

}).compose(this.bindUntilEvent(ActivityEvent.DESTROY)).subscribe(motionEvent -> {});

RxView.touches(layoutVideo, motionEvent -> {

dealLayoutTouch(layoutVideo, motionEvent);

return false;

}).compose(this.bindUntilEvent(ActivityEvent.DESTROY)).subscribe(motionEvent -> {});

}

private void dealLayoutTouch(View v, MotionEvent event) {

switch (event.getAction()) {

case MotionEvent.ACTION_DOWN:

v.setBackgroundColor(Color.rgb(200, 200, 200));

break;

case MotionEvent.ACTION_UP:

v.setBackgroundColor(Color.WHITE);

break;

}

}

显示对话框：

dialogSelectCall.show()

DialogFragment实现源码：

定义了一个类SelectCallDialog.Java继承DialogFragment

package com.bazhangkeji.classroom.common;

import android.app.Dialog;

import android.app.FragmentManager;

import android.graphics.Color;

import android.os.Bundle;

import android.support.annotation.NonNull;

import android.view.Gravity;

import android.view.LayoutInflater;

import android.view.MotionEvent;

import android.view.View;

import android.view.ViewGroup;

import android.view.Window;

import android.view.WindowManager;

import android.widget.Button;

import android.widget.RelativeLayout;

import com.bazhangkeji.classroom.R;

import com.bazhangkeji.classroom.session.VideoSessionActivity;

import com.bazhangkeji.classroom.session.VoiceSessionActivity;

import com.jakewharton.rxbinding2.view.RxView;

import com.trello.rxlifecycle2.android.FragmentEvent;

import com.trello.rxlifecycle2.components.RxDialogFragment;

import java.util.concurrent.TimeUnit;

public class SelectCallDialog extends RxDialogFragment {

private Dialog dialog;

private String userId;

/**

* 初始化.必须调用一次

* @param userId: 目标用户id

*/

public void init(String userId) {

this.userId = userId;

}

@NonNull

@Override

public Dialog onCreateDialog(Bundle savedInstanceState) {

dialog = new Dialog(getActivity(), R.style.DialogPopBottom);

View inflate = LayoutInflater.from(getActivity()).inflate(R.layout.dialog_select_call, null);

dialog.setContentView(inflate);

dialog.setCanceledOnTouchOutside(true);

Window window = dialog.getWindow();

WindowManager.LayoutParams lp = window.getAttributes();

lp.gravity = Gravity.BOTTOM;

lp.width = WindowManager.LayoutParams.MATCH_PARENT;

window.setAttributes(lp);

RelativeLayout layoutVoice = (RelativeLayout) inflate.findViewById(R.id.layout_voice);

RelativeLayout layoutVideo = (RelativeLayout) inflate.findViewById(R.id.layout_video);

Button buttonCancel = (Button) dialog.findViewById(R.id.cancel);

RxView.clicks(layoutVoice)

.throttleFirst(2, TimeUnit.SECONDS)

.compose(this.bindUntilEvent(FragmentEvent.DESTROY))

.subscribe(v -> {

dialog.cancel();

VoiceSessionActivity.startActivityCallOut(getActivity(), userId);

});

RxView.clicks(layoutVideo)

.throttleFirst(2, TimeUnit.SECONDS)

.compose(this.bindUntilEvent(FragmentEvent.DESTROY))

.subscribe(v -> {

dialog.cancel();

VideoSessionActivity.startActivityCallOut(getActivity(), userId);

});

RxView.clicks(buttonCancel)

.throttleFirst(2, TimeUnit.SECONDS)

.compose(this.bindUntilEvent(FragmentEvent.DESTROY))

.subscribe(v -> dialog.cancel());

RxView.touches(layoutVoice, motionEvent -> {

dealLayoutTouch(layoutVoice, motionEvent);

return false;

}).compose(this.bindUntilEvent(FragmentEvent.DESTROY)).subscribe(motionEvent -> {});

RxView.touches(layoutVideo, motionEvent -> {

dealLayoutTouch(layoutVideo, motionEvent);

return false;

}).compose(this.bindUntilEvent(FragmentEvent.DESTROY)).subscribe(motionEvent -> {});

return dialog;

}

private void dealLayoutTouch(View v, MotionEvent event) {

switch (event.getAction()) {

case MotionEvent.ACTION_DOWN:

v.setBackgroundColor(Color.rgb(200, 200, 200));

break;

case MotionEvent.ACTION_UP:

v.setBackgroundColor(Color.WHITE);

break;

}

}

}

显示对话框前初始化参数：

selectCallDialog.init(userId);

显示对话框后：

selectCallDialog.show(getFragmentManager(), "");
