布局文件，一个editview加一个右侧发送图标

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/rl_outside_view"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:orientation="horizontal">

    <LinearLayout
        android:id="@+id/rl_inputdlg_view"
        android:layout_width="match_parent"
        android:layout_height="50dp"
        android:layout_alignParentBottom="true"
        android:background="@color/main_bg"
        android:orientation="horizontal"
        android:paddingTop="10dp"
        android:paddingRight="10dp"
        android:paddingBottom="5dp">

        <EditText
            android:id="@+id/et_input_message"
            android:layout_width="0dp"
            android:layout_height="match_parent"

            android:inputType="text|textAutoComplete"
            android:padding="5dp"
            android:textColor="@color/txt0"
            android:textColorHint="@color/txtgray"
            android:textSize="16sp" />

        <ImageView
            android:id="@+id/confrim_btn"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_gravity="center_vertical"
            android:src="@mipmap/sendimage" />

    </LinearLayout>

</RelativeLayout>

代码中调用使用
oncrete（）方法中

 InputEditDialog mInputEditDialog = new InputEditDialog(this, R.style.InputDialog, "请输入修改的内容");
 mInputEditDialog.setmOnTextSendListener(this);

需要弹出输入框的点击事件下

 case R.id.lin_click:
       showInputMsgDialog();
       break;

 /**
     * 发消息弹出框
     */
    private void showInputMsgDialog() {
        WindowManager windowManager = getWindowManager();
        Display display = windowManager.getDefaultDisplay();
        WindowManager.LayoutParams lp = mInputEditDialog.getWindow().getAttributes();
        lp.width = (int) (display.getWidth()); //设置宽度
        mInputEditDialog.getWindow().setAttributes(lp);
        mInputEditDialog.setCancelable(true);
        mInputEditDialog.getWindow().setSoftInputMode(WindowManager.LayoutParams.SOFT_INPUT_STATE_VISIBLE);
        mInputEditDialog.show();
    }

    @Override
    public void onTextSend(String msg) {
        if ( !TextUtils.isEmpty(msg)) {
            //这里就是你的输入框点击发送之后需要做的一些操作
        }
    }
