底部弹出带输入dialog

dialog代码，基本与普通写法一样，只是加一个回调方法

package com.cn.wq.dialog;import android.app.Activity;import android.content.DialogInterface;import android.support.v7.app.AlertDialog;import android.util.Log;import android.view.Gravity;import android.view.KeyEvent;import android.view.LayoutInflater;import android.view.View;import android.view.Window;import android.view.WindowManager;import android.widget.EditText;import android.widget.TextView;import com.cn.wq.dialog.view.ResizeLayout;/** * Created by dick on 2017/9/22. */public class DialogInputUtils {    private static DialogInputUtils instance;    private AlertDialog dialog;    private EditText mEditText;    private TextView mTvSend;    private boolean isShowInput = false;    private OnTalkClickListener onTalkClick;    private DialogInputUtils() {    }    public static DialogInputUtils getInstance() {        if (instance == null) {            synchronized (DialogInputUtils.class) {                if (instance == null) {                    instance = new DialogInputUtils();                }            }        }        return instance;    }    public void setOnTalkClick(OnTalkClickListener onTalkClick) {        this.onTalkClick = onTalkClick;    }    public interface OnTalkClickListener {        void onTalkClick(String content);    }    /**     * cid救援单ID     *     * @param activity     */    public void showInputDialog(final Activity activity) {        AlertDialog.Builder builder = new AlertDialog.Builder(activity, R.style.Dialog_Fullscreen);        final View view = LayoutInflater.from(activity).inflate(R.layout.dialog_edittext, null);        builder.setView(view);        builder.setCancelable(true);    //设置按钮是否可以按返回键取消,false则不可以取消        //创建对话框        dialog = builder.create();        dialog.setCanceledOnTouchOutside(true); //设置弹出框失去焦点是否隐藏,即点击屏蔽其它地方是否隐藏        final Window dialogWindow = dialog.getWindow();        dialogWindow.setGravity(Gravity.BOTTOM);        addListener(view);        dialog.show();        //获取焦点//        //设置大小        setDialog(activity);    }    private void setDialog(final Activity activity) {        WindowManager.LayoutParams lp = dialog.getWindow().getAttributes();        lp.x = 0;        lp.y = 0;        lp.width = WindowManager.LayoutParams.MATCH_PARENT;        final int height = (int) activity.getResources().getDimension(R.dimen.parent_list_height);        lp.height = height;        dialog.getWindow().setAttributes(lp);        mEditText = (EditText) dialog.getWindow().findViewById(R.id.edt_text);        mTvSend = (TextView) dialog.getWindow().findViewById(R.id.tv_send);        mEditText.setOnKeyListener(new View.OnKeyListener() {            @Override            public boolean onKey(View v, int keyCode, KeyEvent event) {                if (keyCode == KeyEvent.KEYCODE_ENTER || keyCode == KeyEvent.KEYCODE_BACK) {                    dialog.dismiss();                }                return false;            }        });        mEditText.postDelayed(new Runnable() {            @Override            public void run() {                KeyboardUtils.showSoftInput(mEditText);            }        }, 150);        //自动弹出输入法框        dialog.setOnDismissListener(new DialogInterface.OnDismissListener() {            @Override            public void onDismiss(final DialogInterface dg) {                //调用系统输入法                if (isShowInput) {                    KeyboardUtils.toggleSoftInput(activity);                }            }        });        mTvSend.setOnClickListener(new View.OnClickListener() {            @Override            public void onClick(View v) {                Log.w("input", "点击了发送");                if (DialogInputUtils.this.onTalkClick != null) {                    DialogInputUtils.this.onTalkClick.onTalkClick(mEditText.getText().toString());                }            }        });    }    private void addListener(View view) {        final ResizeLayout rootLayout = (ResizeLayout) view.findViewById(R.id.resize_layout);        rootLayout.setListener(new ResizeLayout.Listener() {            @Override            public void onSoftKeyboardShown(boolean isShowing) {                Log.w("input", "--------->isShowingL:" + isShowing);                isShowInput = isShowing;            }        });    }}

2 resizeLayout 内容，由于需要监听dialog的关闭与打开，系统提供的方法很不管用，只能通过自定义方式实现，在这里我是通过dialog打开与关闭时的坐标变化，来判断dialog是打开还是关闭状态

    package com.cn.wq.dialog.view;import android.content.Context;import android.util.AttributeSet;import android.util.Log;import android.widget.EditText;import android.widget.LinearLayout;import com.cn.wq.dialog.R;public class ResizeLayout extends LinearLayout {    private static int count = 0;    private final int keyHeight;    private EditText editText;    private int[] position = new int[2];    private final int screenHeight;    public ResizeLayout(Context context, AttributeSet attrs) {        super(context, attrs);        //获取屏幕高度        screenHeight = ScreenUtils.getScreenHeight(context);        //阀值设置为屏幕高度的1/3        keyHeight = screenHeight / 3;        Log.w("input", "screenHeight:" + screenHeight);    }    @Override    protected void onLayout(boolean changed, int l, int t, int r, int b) {        super.onLayout(changed, l, t, r, b);//        Log.w("input " + count++, "=>OnLayout called! l=" + l + ", t=" + t + ",r=" + r + ",b=" + b);        if (editText == null) {            editText = (EditText) this.findViewById(R.id.edt_text);        }        if (editText != null) {            editText.getLocationOnScreen(position);            Log.w("input", "\t position on screenY:" + position[1]);            if (listener != null)                listener.onSoftKeyboardShown(position[1] < screenHeight * 0.7);        }    }    public interface Listener {        public void onSoftKeyboardShown(boolean isShowing);    }    private Listener listener;    public void setListener(Listener listener) {        this.listener = listener;    }    @Override    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {        super.onMeasure(widthMeasureSpec, heightMeasureSpec);    }}

3 layout比较简单

<?xml version="1.0" encoding="utf-8"?><com.cn.wq.dialog.view.ResizeLayout xmlns:android="http://schemas.android.com/apk/res/android"    android:id="@+id/resize_layout"    android:layout_width="match_parent"    android:layout_height="wrap_content"    android:orientation="vertical">    <LinearLayout        android:layout_width="match_parent"        android:layout_height="wrap_content"        android:orientation="vertical">        <RelativeLayout            android:layout_width="match_parent"            android:layout_height="wrap_content">            <EditText                android:id="@+id/edt_text"                android:layout_width="match_parent"                android:layout_height="40dp"                android:layout_centerVertical="true"                android:hint="说说看"                android:background="@drawable/edit_bg_shape"                android:textSize="15sp"                android:imeOptions="actionDone"                android:paddingLeft="20dp" />            <TextView                android:id="@+id/tv_send"                android:layout_width="wrap_content"                android:layout_height="40dp"                android:layout_alignParentRight="true"                android:layout_centerVertical="true"                android:gravity="center"                android:paddingRight="20dp"                android:text="发送"                android:textSize="17sp"                android:textColor="@android:color/holo_green_dark" />        </RelativeLayout>    </LinearLayout></com.cn.wq.dialog.view.ResizeLayout>
